The Soils of Bulgaria offers a comprehensive analysis of the characteristics of soils and concepts on their magnitude. The purpose of the book is to introduce readers to the soil problematic and ecology in Bulgaria. The volume is divided into 3 parts. The first includes historical facts on soil research in Bulgaria, as well as general conditions and factors of soil formation, while the second applies an original pedological approach. The book's third part focuses on essential information concerning land use/cover in Bulgaria. Each of the 13 chapters deals more specifically with fundamental chemical and physical soil properties, concepts of soil evolution, old and modern processes, geographic distribution, climatic conditions, topography, parent materials, plant associations, morphology and the relationship with different classification systems. The interactions between soil status and management are also highlighted. The use of the latest, statistically significant data ensures precise conclusions. The book also includes a large number of charts and new illustrations. The Soils of Bulgaria is crucial reading material for anyone interested in soil management and agriculture in Easter Europe, from students to policy makers and is also of particular interest for researchers in the field.

This book addresses the geology of the entire Himalayan range in Nepal, i.e., from the Gangetic plain in the south to the Tethyan zone in the north. Without a comprehensive look at the various Himalayan zones, it is practically impossible to fully grasp the processes at work behind the formation and development of the spectacular Himalaya. However, the goal is not merely to document all the scientific ontology but rather to reveal a sound basis for the prevailing concepts. Both the early literature on Himalayan geology and contemporary trends are fully covered. For the first time, the origin, use, and abuse of common Himalayan geological terms such as the Siwaliks, Lesser Himalaya, Main Boundary Thrust, Main Central Thrust, and Tethys are discussed. The book will help readers to progress from a cognitive approach to a constructive one by linking various types of knowledge, such as seeking relations between various geological structures as well as between earlier thoughts or views and contemporary approaches.

Modeling of Magmatic and Allied Processes presents methods and models for the quantification of geological processes. Conceptual models for magmatic differentiation involving crystallization and mixing are presented and applied to field and textural data. Model equations for the degree of partial melting in presence perturbations of lithospheric geotherms and partitioning of trace/radioactive elements in the matrix and melts, and the formation of continents with melt additions are described.  Diverse magmatic products are shown to result from differentiation processes rather than magmatic source heterogeneities. The degree of partial melting depends on mantle temperatures, for which parameterized thermal convection models are reviewed. Perturbations in geotherms caused by mantle heat flow, CO2 flux from great depths and tectonic thrusting are analyzed. The petrogenetic significance of accessory minerals of felsic magma evolution is assessed with the help of examples from Carpathian granitoids. Methods for simulating the 3-D Concentration and Distribution Models (DC-DMs) and fractal dimension of evolving magma systems are described with examples. The use of conventional scanning electron microscopy methods and electron microprobe to characterize and infer magmatic processes is explained, and the background and economic potential of hydrothermal systems are examined. The nature of oxidizing felsic magmas along with their potential for copper mineralization is discussed. In closing, the handling, calculation and plotting of geochemical data for igneous rock suites using the R-language-based software Geochemical Data Toolkit (GCDkit) along with plug-in modules for the forward and reverse mass-balance calculation of fractional crystallization are demonstrated.

The Landscapes and Landforms of Spain provides an informative and inviting overview of the geology and geomorphology of Spain. It incorporates a diverse range of topics, ranging from the fiery landscapes of the Canary Islands and its volcanic formations to the glacial scenery of the Pyrenees. The book devotes attention to granite landforms, karst terrains, coastal dunes and marshes, as well as to heritage and conservation, with the objective of offering the reader a comprehensive insight into the Spanish geological setting. The book presents readers with the opportunity to explore Spanish landforms in detail through its highly illustrated pages and maps, making this an appealing text on the subject field.

North-East India, comprising the seven contiguous states around Assam, the principal state of the region, is a relatively unknown, yet very fascinating region. The forest clad peripheral mountains, home to indigenous peoples like the Nagas, Mizos and the Khasis, the densely populated Brahmaputra valley with its lush green tea gardens and the golden rice fields, the moderately populated hill regions and plateaus, and the sparsely inhabited Himalayas, form a unique mosaic of natural and cultural landscapes and human interactions, with unparalleled diversity. The book provides a glimpse into the region's past and gives a comprehensive picture of its physical environment, people, resources and its economy. The physical environment takes into account not only the structural base of the region, its physical characteristics and natural vegetation but also offers an impression of the region's biodiversity and the measures undertaken to preserve it. The people of the region, especially the indigenous population, inhabiting contrasting environments and speaking a variety of regional and local dialects, have received special attention, bringing into focus the role of migration that has influenced the traditional societies, for centuries. The book acquaints the readers with spatial distribution, life style and culture of the indigenous people, outlining the unique features of each tribe. The economy of the region, depending originally on primitive farming and cottage industries, like silkworm rearing, but now greatly transformed with the emergence of modern industries, power resources and expanding trade, is reviewed based on authentic data and actual field observations. The epilogue, the last chapter in the book, summarizes the authors' perception of the region and its future.

This edited volume, showcasing cutting-edge research, addresses two primary questions - what are the main drivers of change in high-mountains and what are the risks implied by these changes? From a physical perspective, it examines the complex interplay between climate and the high-mountain cryosphere, with further chapters covering tectonics, volcano-ice interactions, hydrology, slope stability, erosion, ecosystems, and glacier- and snow-related hazards. Societal dimensions, both global and local, of high-mountain cryospheric change are also explored. The book offers unique perspectives on high-mountain cultures, livelihoods, governance and natural resources management, focusing on how global change influences societies and how people respond to climate-induced cryospheric changes. An invaluable reference for researchers and professionals in cryospheric science, geomorphology, climatology, environmental studies and human geography, this volume will also be of interest to practitioners working in global change and risk, including NGOs and policy advisors.

Born in Hungary, the geologist Angelo Heilprin (1853-1907) moved with his family to the United States as a boy. He later left New York to study natural sciences in distinguished European institutions, and went on to hold academic positions in Philadelphia and ultimately at Yale. His teaching duties were interspersed with expeditions to Yucatan, Greenland and other places of geological interest. This 1904 study, complemented by unique photographs, depicts his third visit to the island of Martinique in the aftermath of the devastating eruptions of Mount Pelee in 1902. Heilprin documents the temporary formation of Pelee's 'tower', a monolith of lava that grew rapidly after the eruptions, reaching a height of 300 metres before its collapse. Heilprin also summarises the chief features of volcanic eruptions and directs readers to his 1903 publication Mont Pelee and the Tragedy of Martinique (also reissued in this series) for further information.

This book brings together works published between 1846 and 1859 by the Scot James D. Forbes (1809-68) and Irishman John Tyndall (1820-93), both of whom were experienced alpinists as well as glaciologists. However, their views on the motion of glaciers were disparate, and a scientific quarrel over primacy and credit for discoveries continued even after their respective deaths. These papers include Forbes' articles on experiments on the flow of plastic bodies and analogies between lava and glacier flows, and on the plasticity of glacier ice, as well as Tyndall's observations on the physical phenomena of various Alpine glaciers, including the famous 'Mer de Glace', and a piece on the structure and motion of glaciers, co-written with Thomas Huxley. Several works by and about all three scientists (including works on Alpine travel) have also been reissued in this series.

Sedimentary basins host, among others, most of our energy and fresh-water resources: they can be regarded as large geo-reactors in which many physical and chemical processes interact. Their complexity can only be well understood in well-organized interdisciplinary co-operations. This book documents how researchers from different geo-scientific disciplines have jointly analysed the structural, thermal, and sedimentary evolution as well as fluid dynamics of a complex sedimentary basin system which has experienced a variety of activation and reactivation impulses as well as intense salt tectonics. In this book we have summarized our geological, geophysical and geochemical understanding of some of the most important processes affecting sedimentary basins in general and our view on the evolution of one of the largest, best explored and most complex continental sedimentary basins on Earth: The Central European Basin System.

This book offers a unique collection of inter- and multidisciplinary studies on river systems. Rivers have been the prime source of sustenance since the advent of civilization and river systems often form the basis for agriculture, transport, water, and land for domestic, commercial, and industrial activities, fostering economic prosperity. A river basin is a basic geographical and climatological unit within which the vagaries of natural processes act and manifest themselves at different spatio-temporal scales. Even if compared side-by-side, no two river basins respond to natural processes in the same way and thus, it has long been recognized that each river basin is unique. Hence, any developmental activity or conservation effort has to be designed and implemented to match each unique river basin. With the burgeoning population and increasing dependency on natural resources, understanding and maintaining river systems has become increasingly important. This book provides a varied reference work on and unprecedented guidelines for conducting and implementing research on river basins, and for managing their ecological development.

In the early nineteenth century, the gifted stratigrapher and amateur geologist William Phillips (1773-1828) gave several lectures to interested young people in Tottenham on the subject of geology. These lectures were later collected into a book, which Phillips expanded in later versions. This reached its peak in 1822 when the clergyman William Daniel Conybeare (1787-1857) collaborated with Phillips to produce this rigorous and improved assessment of the geological composition of England and Wales. Although no second volume was ever published, the book had a tremendous impact on geologists throughout the United Kingdom and Europe, inspiring foreign scholars to produce equivalent volumes about their own countries. Conybeare's concern for the stratigraphy of fossils is especially remarkable for the time. William Fitton, later president of the Geological Society of London, praised the book highly, remarking that 'no equal portion of the earth's surface has ever been more ably illustrated'.

This work reviews the mechanism of rifting with a focus on pre-existing tectonic weaknesses in pre-rift and/or basement rocks, i.e., on tectonic inheritance. The passive margins that are studied in this book are the Norwegian Continental Shelf, the Eastern North America and the East and West Indian Continental Margins. The continental rifts that have been analysed are the East African Rift System, the Brazilian Continental Rift Systems and the European Cenozoic Rift System. It states how rifts and passive margins serve as valuable locations for hydrocarbon exploration. Tectonic inheritance/heritage examines the influence of pre-existing/pre-rift elements on the geometry, genesis and propagation of rift-related faults. Such elements include anisotropies in the shallow crustal levels, as well as the rheology of the lithosphere. Inheritance greatly influences the architecture of rifted passive margins including the attitude of faults and geometry of horsts, (half-) grabens, transfer zones etc. Inheritance is also a determining factor in the width of rifts and rift shoulder topography.

This book describes the nature and origin of the Macraes gold deposit. It also documents the key features of this spectacular deposit for a wide range of professionals in the resource geology community. This world-class gold deposit has been a spectacular geological and economic success story, as it has developed from a small historical gold mine in discontinuous quartz veins measuring only meters to a large-scale mine in deposits spreading over kilometres in extensive disseminated gold-bearing rock.

Our understanding of the rheological and seismic properties of the Earth's interior relies on interpreting geophysical observations using mineral physics data. The complexity of natural materials complicates these interpretations, but here the key features of such materials in controlling the attenuation of seismic waves are determined by a set of careful experiments. This thesis clearly explains how dynamic mechanical spectroscopy has been used to determine the visco-elastic properties of igneous and sedimentary rocks containing geological fluids. These experiments highlight, for the first time, the importance of mineral and rock microstructures as controls on geophysical properties of solids, particularly near the melting point. The results have impacts in areas ranging from volcanic processes, through the structure of the deep Earth, to fluid-saturated porous media.

This book presents geomorphological and sedimentological aspects of Holocene boulder ridges along the coastline of western Ireland (the Aran Islands and Galway Bay). Given these boulders' size, extent and altitude, they are among the most spectacular deposits moved by marine forces worldwide and have challenged researchers to solve their enigmatic history. In particular, the question of how their features were formed (by storm waves or by tsunamis) is a matter of heated debate. The documentation is based on the authors' own field research, including observations on the boulder transport capacity of six extremely strong winter storms in the 2013/14 season. Discussing the arguments published to date and using more than 130 images for clarity, the book addresses the character, setting and extraordinary size of these boulders moved on land, comparing them with the situation along other exposed coastlines of the world.

Soil as World Heritage celebrates a half century of field experiments on the Balti Steppe, in Moldova - where Dokuchaev first described the Typical Chernozem in 1877, protected from the elements by a unique system of shelter belts designed by the great man, and now provisionally listed as the first World Heritage Site for soil. The book presents contributions to the 2012 international symposium attended by researchers, practitioners and policy makers from the European Commission and countries as diverse as Belarus, Bulgaria, the Czech Republic, France, Germany, Italy , the Netherlands, Romania, Russia, Ukraine, United Kingdom, USA and, of course, Moldova itself. The experimental data demonstrate the damage caused by human activity to the productivity and integrity of the black earth and, also, ways to restore its fertility. Results from even longer-established trials worldwide also demonstrate that agricultural practices are driving global warming, leaching of nutrients, pollution of water resources, diversion of rainfall away from replenishment of soil and groundwater to destructive runoff, and destroying soil organic matter and biodiversity. These are pressing issues for our generation and will press harder on future generations. Long-term field experiments, and the scientific skills and experience that they nurture, will be more and more valuable as a foundation and focus for interdisciplinary teams studying the effects of farming practices on the soil and soil life so as to devise a sustainable alternative. Europe-wide and worldwide contributions also discuss economic incentives - carbon and green water credits - which themselves require robust supporting data, and legislative aspects of promoting more sustainable farming systems. The outcomes of the conference include recommendations for institutional support for sustainable farming and a draft of the law on land and soil management for the Parliament of Moldova.

The Scottish geologist Sir Roderick Impey Murchison (1792 1871) first proposed the Silurian period after studying ancient rocks in Wales in the 1830s. Naming the sequence after the Silures, a Celtic tribe, he believed that the fossils representing the origins of life could be attributed to this period. This assertion sparked a heated dispute with his contemporary Adam Sedgwick, ultimately ruining their friendship. First published in 1854, Siluria is a significant reworking of Murchison's earlier book, The Silurian System, which had appeared in 1839. Thorough in his approach, he combines his own findings with those of researchers around the world, touching also on the later Devonian, Carboniferous and Permian periods as well as questions of natural history. An important text in nineteenth-century geology and palaeontology, the work contains a valuable geological map of Wales along with detailed engravings of fossils, including crustaceans, cephalopods and fish."

Impressed by the discoveries of Captain Cook, and conscious that Russia was lagging behind other countries in terms of navigation and exploration, Catherine the Great commissioned an expedition in 1785 to chart the coastline in the far north-east of her empire. Born in Middlesex, Joseph Billings (1758 1806) had sailed under Cook but entered Russian service in 1783. He was chosen to lead the expedition, which would last for nine years. Written up by Martin Sauer, secretary and translator to the expedition, this illustrated account was first published in English in 1802, documenting the sheer scale of the task and the range of scientific activities carried out. Notable for producing the first accurate maps of the shoreline and islands of east Siberia, the expedition also contributed to the ethnographic and zoological knowledge of this most inhospitable of environments."

Cornwall has one of the oldest mining histories in Europe. At one time, the county was a leading producer of tin, with over 2,000 mines in operation, but competition from overseas saw the boom years of the mid-nineteenth century give way to steady decline. Brenton Symons (1832 c.1908), an experienced mining engineer and metallurgist, firmly believed that the mineral wealth of Cornwall was far from exhausted and that careful application of financial investment and skilled personnel could boost the county's prosperity. This illustrated monograph, published in 1884, is his account of Cornwall's geological characteristics, giving details of the formation, location and economic use of various mineral deposits, and describing the extraction techniques of the key mining districts. Accessible and authoritative, this book remains relevant to readers interested in mineralogy, mining and the economic history of Cornwall."

Design happens everywhere, whether in animate objects (e.g., dendritic lung structures, bacterial colonies, and corals), inanimate patterns (river basins, beach slope, and dendritic crystals), social dynamics (pedestrian traffic flows), or engineered systems (heat dissipation in electronic circuitry). This "design in nature" often takes on remarkably similar patterns, which can be explained under one unifying Constructal Law. This book explores the unifying power of the Constructal Law and its applications in all domains of design generation and evolution, ranging from biology and geophysics to globalization, energy, sustainability, and security. The Constructal Law accounts for the universal tendency of flow systems to morph into evolving configurations that provide greater and easier access over time. The Constructal Law resolves the many and contradictory ad hoc statements of "optimality", end design, and destiny in nature, such as minimum and maximum entropy production and minimum and maximum flow resistance, and also explains the designs that are observed and copied in biomimetics. Constructal Law and the Unifying Principle of Design covers the fundamentals of Constructal Theory and Design, as well as presenting a variety of state-of-the-art applications. Experts from the biological, physical and social sciences demonstrate the unification of all design phenomena in nature, and apply this knowledge to novel designs in modern engineering, such as vascularization for self-healing and self-cooling materials for aircraft, and tree fins and cavities for heat transfer enhancement.

This pioneering work deals with the parameterization of rockfalls in the context of 3D run-out modelling at a study site in the Bavarian Alps. The main objective was to cover not only low-magnitude, high-frequency rockfalls (<10 m3) but also Mid-Magnitude events, which involve rock volumes of between 10 and 100 m3 (boulder falls) and between 100 and 10,000 m3 (block falls). As Mid-Magnitude events have been insufficiently covered in terms of rockfall modelling up to now, a geomechanical approach has been developed to characterize those events by means of a case study. For a 200 m3 limestone block a potential failure scenario was analysed by combining a deterministic failure analysis with a numerical process-based run-out model. To model potential run-out scenarios of the 200 m3 block, the beta version of the code RAMMS::Rockfall, developed by the Swiss Institute for Snow and Avalanche Research (SLF), was applied. RAMMS::Rockfall makes it possible to include the block shape and thus consider the effects of varying block shapes on the run-out distance. The run-out modelling for the entire project site was performed using the scientific code Rockyfor3D (Dorren/ecorisQ). To provide quantitative information in terms of input parameters, a field recording of block sizes at the talus slope, as well as a detailed discontinuity analysis at the source area, were conducted. The book successfully demonstrates how detailed and quantitative field investigation can contribute to 3D rockfall modelling.

This book discusses the perceptions and sketches, geological background, materials and coastal processes of the East Coast of India. It also suggests strategies for effectively managing natural coastal processes in these areas. India has a coastline of about 7,516 km with a variety of coastal extensions, which developed at different time scales, producing permanent variations in the morphologies of the coastal areas through hydrodynamic, fluvial, aeolian and terrestrial processes. The book focuses on the Balasore coast, an area drained by three main rivers (the Subarnarekha, the Dugdeugi and the Burahbolong), which impacts the coastal morphodynamic processes of the area and accounts for their multifaceted nature. Large drops or increases in the sediment supply within a short time span or over prolonged periods cause shoreline shifting. Eight satellite images from 1975, 1980, 1990, 1995, 2000, 2005, 2010 and 2013 were used to measure the shoreline dynamics, and a reference line was established using first order polynomial model with base data with 0.5 pixel root mean square error (RMSE) accuracy. The end point rate (EPR) model was adopted for estimating the future position of the shoreline. In order to assess the beach morphodynamics, the coastal modeling system (SMC) was used, which incorporates with a series of appliances and numerical models structured consistent with the space and time scale of the different dynamics affecting the littoral and beach morphology based on diverse thematic and reference documents. This study employed short-term analysis using the MOPLA module of the SMC system, which consists of three attached modules: the wave transformation module (Oluca), the depth-averaged currents module (Copla) and the sediment transport and morphological evolution module (Eros). The shoreline dynamics findings show that the magnitude of erosion is higher in the northern part of the coastline in the left bank area of the Subarnarekha river estuary and in the estuarine part of the Dugdugi and Burahbalang rivers. The southern part of the shoreline near Rasalpur and Joydevkasba is relatively stable, and the study suggests that the current shoreline shift trend will continue in the future. The SMC model indicates that the wave height, significant wave height, current velocity and the potential transport of sediment at the Kirtaniya study point are high, while at Choumukh they are low and at the Rasalpur study point they are intermediate.

Landslides represent one of the most destructive natural catastrophes. They can reach extremely long distances and velocities, and are capable of wiping out human communities and settlements. Yet landslides have a creative facet as they contribute to the modification of the landscape. They are the consequence of the gravity pull jointly with the tectonic disturbance of our living planet. Landslides are most often studied within a geotechnical and geomorphological perspective. Engineering calculations are traditionally applied to the stability of terrains. In this book, landslides are viewed as a physical phenomenon. A physical understanding of landslides is a basis for modeling and mitigation and for understanding their flow behavior and dynamics. We still know relatively little about many aspects of landslide physics. It is only recently that the field of landslide dynamics is approaching a more mature stage. This is testified by the release of modelling tools for the simulation of landslides and debris flows. In this book the emphasis is placed on the problems at the frontier of landslide research. Each chapter is self-consistent, with questions and arguments introduced from the beginning.

Inhabited by Polynesians since the thirteenth century and discovered by Europeans in the seventeenth, New Zealand is a geologically diverse island group where active volcanoes and frequent earthquakes have resulted in a rich variety of rock formations and geothermal activity. In 1859 60, the geologist Ferdinand von Hochstetter (1829 84) was employed by Auckland's government to undertake the first systematic geological survey of the islands, the results of which were first published in German in 1863 and translated into this English version in 1867. Hochstetter describes his travels across New Zealand, his encounters with native people and his scientific observations. He analyses plants, wildlife and fossils, describes mountains, rocks and boiling springs, and evaluates evidence of glaciers and tectonic activity. As a result of Hochstetter's work, several species in New Zealand were named after him. This book remains a valuable resource in the history of Australasian natural science.

This book offers an insight into the global occurrence, geomorphology, evolution, weathering and erosion of coastal cliffs and bluffs. Stabilization and preservation of cliffs are treated in detail. Mitigation of cliff hazards and preservation of scenic features and sites of scientific importance requires effective coastal cliff management that can only be based on thorough knowledge of the physical processes at work. Cliffs have been cut in various geological formations, and have taken shape as a sequel to a world-wide sea level rise. Most cliffs have receded as the result of weathering and erosion, but some are now stable. Where they are actively receding, consuming useful agricultural or forested land or threatening coastal structures such as roads, buildings and seaside towns, it may be necessary to halt their retreat, or at least to modify it, by coastal cliff management.
