Thermal enrichment of coldwater streams by heated stormwater in summer months is often overlooked and even exacerbated by traditional management practices that typically account for flow moderation and pollutant removal only. Initiated in 1999, this study evaluated and identified innovative and traditional approaches to moderate this temperature impact by monitoring and analyzing the hydrologic and thermal regimes of an urban stormwater treatment system consisting of two traditional wet detention ponds and an enhanced natural wetland. Data analysis clearly shows temperature increases in the open detention ponds and the ability of the wetland to mitigate this thermal enrichment. Event-based thermal loading and temperature regime analysis indicated flow reduction via infiltration and effective vegetative cover in the wetland were the primary mechanisms for mitigating stormwater thermal enrichment. Using the concept of temperature equivalent, we also established the locations and strength of thermal enrichment areas. A heat transfer model was developed to simulate runoff temperature. Results indicated that rainfall characteristics, temperature difference between rainfall and the ground surface, and the runoff flow depth were the most important factors affecting runoff temperature.
Effective management of a water well requires that the water well can meet a set of performance indicators. These can include criteria related to water quality, yield, economics and asset life. Water well deterioration due to fouling and corrosion impacts the ability of a well system to meet these criteria. Managing well deterioration processes involves understanding the nature of these processes and having in place water well maintenance strategies to deal with them. Managing water well deterioration fills a need within the literature for an academically based informative text that incorporates practical advice. The focus on a problem-oriented approach to diagnosing well deterioration makes the book a useful practical handbook. It integrates concepts from hydrogeology, hydrochemistry and microbiology to give a thorough understanding of water well deterioration processes. Scenarios have been developed to illustrate common causes of water well fouling. A feature of the book is the treatment of both corrossion and fouling issues in depth. Case studies selected from around the world are uses to illustrate approaches to the diagnosis and remediation of well deterioration. These scientifically orientated perspectives on water well deterioration are embedded within a management framework to provide a comprehensive approach to dealing with water well deterioration.
Viktor Schauberger (1885-1958) combined precise observation of nature and intuition with hard science and engineering. He researched into the real nature of water. Natural water, says Schauberger, is a living organism, akin to blood in the human body. It is the most important life-giving and energy-empowering substance on the planet. It nourishes the whole biosphere and, when it becomes corrupted, the ecosystem becomes sick. Through the tireless study of mountain streams and rivers, Schauberger was able to show the importance of energy in water, and how nature uses this to create life. He engaged contemporary scientists in heated debates about where he saw they were going wrong. Sadly, the same extractive and water-management policies which brought devastation in his day have even greater consequences today, and the world will reject at its peril Schauberger's pleas to rediscover how to work with nature. This is the first volume of "Eco-Technology", a series based on the writings and discussions of Viktor Schauberger. The other volumes will cover Schauberger's research on trees, soils and the atmosphere and his practical applications for working with nature. In public, Schauberger

Deterministic Methods in Systems Hydrology presents the basic theory underlying the multitude of parameter-rich models which dominate the hydrological literature. Its objectives are to introduce the elements of systems science as applied to hydrological problems; to present flood prediction and flood routing as problems in linear systems theory, clarifying the basic assumptions and evaluating their accuracy; and to review and to evaluate some deterministic models of components of the hydrological cycle, with a view to assembling the most appropriate model of catchment response, for a particular problem in applied hydrology. The material is developed in two parts: the first four chapters present the systems viewpoint, the nature of hydrological systems, some systems mathematics and their application to direct storm runoff. The final four chapters cover linear conceptual models of direct runoff, the fitting of conceptual models to data, simple models of subsurface flow and non-linear deterministic models.

This is the fifth and last volume representing the proceedings of the International Conference on Water Resources Management in Arid Regions held March 23rd-27th 2002 in Kuwait. This book discusses major aspects of hydrology and water resources. It presents papers on important aspects of surface water and groundwater hydrology, including drought tendencies, regional flood frequency analysis, urban storm drainage with curb-opening inlets, isotopic investigations for lakes, hydrologic and sediment transport modeling, groundwater exploration using remote sensing and GIS, origin and recharge rates of alluvial ground waters, stormwater and groundwater management, and considerations for stochastic finite element in geostatistics and modeling. Papers on water quality supplement the discussion.
Modeling hydrologic changes and predicting their impact on watersheds is a dominant concern for hydrologists and other water resource professionals, civil and environmental engineers, and urban and regional planners. As such changes continue, it becomes more essential to have the most up-to-date tools with which to perform the proper analyses and modeling of the complex ecology, morphology, and physical processes that occur within watersheds. An application-oriented text, Modeling Hydrologic Change: Statistical Methods provides a step-by-step presentation of modeling procedures to help you properly analyze and model real-world data.
The book presents improved equations for monthly water resources models, in particular for interception and transpiration. Most of the existing monthly models do not make a distinction between interception and transipiration, while this distinction is very important for management purposes. Interception is direct feedback to the atmosphere, important to sustain rainfall. Transpiration is a good indicator for plant growth and biomass production. This distinction also contributes to the estimation of recharge and therewith of runoff.;The derivations are based on the Markov theory for the occurrence of rain-days. The methodology can be used on the basis of an analysis of a few time series of daily data, at a spatial scale of 300km and not necessarily of the same period as the monthly data. Zimbabwe served as the case study, but derived equations can be used worldwide as long as the relationship between the monthly rainfall and the mean number of rain-days can be established.
In 2017 four rivers in Aotearoa New Zealand, India, and Colombia were given the status of legal persons, and there was a recent attempt to extend these rights to the Colorado River in the USA. Understanding the implications of creating legal rights for rivers is an urgent challenge for both water resource management and environmental law. Giving rivers legal rights means the law can see rivers as legal persons, thus creating new legal rights which can then be enforced. When rivers are legally people, does that encourage collaboration and partnership between humans and rivers, or establish rivers as another competitor for scarce resources? To assess what it means to give rivers legal rights and legal personality, this book examines the form and function of environmental water managers (EWMs). These organisations have legal personality, and have been active in water resource management for over two decades. EWMs operate by acquiring water rights from irrigators in rivers where there is insufficient water to maintain ecological health. EWMs can compete with farmers for access to water, but they can also strengthen collaboration between traditionally divergent users of the aquatic environment, such as environmentalists, recreational fishers, hunters, farmers, and hydropower. This book explores how EWMs use the opportunities created by giving nature legal rights, such as the ability to participate in markets, enter contracts, hold property, and enforce those rights in court. However, examination of the EWMs unearths a crucial and unexpected paradox: giving legal rights to nature may increase its legal power, but in doing so it can weaken community support for protecting the environment in the first place. The book develops a new conceptual framework to identify the multiple constructions of the environment in law, and how these constructions can interact to generate these unexpected outcomes. It explores EWMs in the USA and Australia as examples, and assesses the implications of creating legal rights for rivers for water governance. Lessons from the EWMs, as well as early lessons from the new 'river persons,' show how to use the law to improve river protection and how to begin to mitigate the problems of the paradox.
Environmental contamination in cold regions poses unique problems. It affects traditionally pristine areas and presents substantial operational difficulties. The extreme temperature range, soils and geology, the unique biological diversity, the freezing and thawing of pollutants, and the impact of human activities make environmental site assessment and remediation a challenging task.
The efficient management of water supply becomes even more important in arid areas where supply is at best erratic. This book looks at a range of issues connected to urban and agricultural water use in the Sana'a Plain area, including engineering and logisical problems, environmental and climatic influences on groundwater, legal and political wrangles, economic considerations and options for waste water re-use.
The Zambezi river basin is the fourth largest river basin in Africa and drains a total of some 1350.000 square km. The basin drains eight countries: Angola, Botswana, Malawi, Mozambique, Namibia, Tanzania, Zambia and Zimbabwe. The river flows over the famous Victoria Falls into the third largest artificial lake in the world: Lake Kariba. The Zambezi Basin is rich in natural resources and has a large hydro-power potential. This volume contains 37 papers which have been published in international journals, or presented at international conferences by the Zambezi River Authority staff. The topics covered include: Dam Safety, Rehabilitation and Maintenance, Environment and Health, Hydrology, Limnology, Information Systems, Water Resource Management, Hydropower Development and Socio-Economic Issues.
Rivers of the World, vividly written and meticulously researched, is a rich and thorough treatment of some 200 of the world's rivers. In this comprehensive treatment of the major rivers of the world, author James R. Penn's purpose is not just to feature geographic data, but to tell a story of historical drama, poetic significance, and cultural relationships. The book shows glimpses of Chairman Mao boosting his image by swimming in the Yangtze; Indian middlemen residing on both sides of the Columbia River exacting tolls from travelers like Lewis and Clark; and, near the Dordogne in southwest France, Paleolithic cave art, paintings, and designs in rock shelters and subterranean caverns, which are textbook examples of early human creativity and artistic impulse. In nearly 200 entries ranging from a few paragraphs to several pages, Rivers of the World covers all of the great rivers of the world including the Nile, Niger, Amazon, and Mississippi, as well as smaller waterways that illustrate important themes or represent trends. The book includes bibliographies for each river.
The importance and ecological significance of estuaries has been long appreciated. In the last few years, there has been increased research activity, resulting in significant advances in understanding of estuarine ecology. This special thematic volume of Advances in Ecological Research provides an overview of a number of the important areas. Ranging from the macroscale: how differences in river basins influence the loads of nutrients, through the impacts and fates of the nutrient loads, to how both phytoplanktonic and benthic estuarine primary production are regulated. There is also a review of the key factors influencing the outcome of management decisions for estuaries from the point of sustainability of estuarine resources. This volume is essential reading and reference for all those interested in estuaries including ecologists, environmental scientists, botanists, and zoologists.
In a never-ending battle to match population growth with food and energy production, the countries of the Middle East have been frenziedly developing water resources, including international rivers and groundwate, without considering their neighbors' needs. The inevitable result has been more frequent and increasingly bitter conflicts. At the same time, a halting Arab-Israeli peace process spurred by the collapse of the Soviet Union continues. Are we indeed entering a new era in a new Middle East? Do the region's leaders understand that reality has changed and that a transition is inevitable? Focusing on international rivers and ground water in the region, this timely study provides thoughtful_if pessimistic_answers to these questions. Encompassing all water sources in the Middle East, Arnon Soffer thoroughly explores the Nile, Tigris, Euphrates, Jordan, Orontes, and Litani Rivers, as well as international groundwater. He also weighs the implications of going to war over water and such unconventional solutions to the water shortage as desalination and importation.
As introduced in Dr. Lee's 10-week class, Applied Mathematics in Hydrogeology is written for professionals and graduate students who have a keen interest in the application of mathematics in hydrogeology. Its first seven chapters cover analytical solutions for problems commonly encountered in the study of quantitative hydrogeology, while the final three chapters focus on solving linear simultaneous equations, finite element analysis, and inversion for parameter determination. Dr. Lee provides various equation-solving methods that are of interest to hydrogeologists, geophysicists, soil scientists, and civil engineers, as well as applied physicists and mathematicians. In the classroom, this same information will help students realize how familiar equations in hydrogeology are derived-an important step toward development of a student's own mathematical models. Unlike other applied mathematics books that are structured according to systematic methodology, Applied Mathematics in Hydrogeology emphasizes equation-solving methods according to topics. Hydrogeological problems and governing differential equations are introduced, including hydraulic responses to pumping in confined and unconfined aquifers, as well as transport of heat and solute in flowing groundwater.
This book represents a new "earth systems" approach to catchments that encompasses the physical and biogeochemical interactions that control the hydrology and biogeochemistry of the system. The text provides a comprehensive treatment of the fundamentals of catchment hydrology, principles of isotope geochemistry, and the isotope variability in the hydrologic cycle -- but the main focus of the book is on case studies in isotope hydrology and isotope geochemistry that explore the applications of isotope techniques for investigating modern environmental problems.
Palaeohydrological research is a comparatively recent development. However, research undertaken has already demonstrated a significant multidisciplinary impact and shown how palaeohydrology can provide an important contribution to the study of global change. Although a considerable amount of exciting palaeohydrological research has been applied to particular areas, there has not previously been a systematic approach to research into the palaeohydrology of the Earth's surface. It was for this reason that a Commission was established by INQUA in 1991 on Global Continental Palaeohydrology. This volume provides the background to that exciting international research project and has been written to provide a basis for understanding the current state of research into the palaeohydrology of the land surface of the Earth. It therefore gives a summary of the work achieved to date and of the research investigations currently taking place, together with an indication of the way in which palaeohydrological research relates to other global research programmes.

Groundwater Geochemistry: Fundamentals and Applications to Contamination examines the integral role geochemistry play s in groundwater monitoring and remediation programs, and presents it at a level understandable to a wide audience. Readers of all backgrounds can gain a better understanding of geochemical processes and how they apply to groundwater systems.
Groundwater abstraction plays a very important part in water supplies throughout the world. Yet too many wells and boreholes operate inefficiently or are abondoned. Until relatively recently, very many water well operators had valuable assets in the form of groundwater abstraction works, of which they really had little idea of condition or operating efficiency. Inadequate monitoring and little if any maintenance occurred. As long as some water was gained little else seemed to matter. If a well failed for some reason, then it was often abandoned and water obtained quickly via an engineering solution varying from drilling a new well, to manipulation of other parts of the supply/distribution system. Rehabilitation, if attempted, was on a "suck-it-and-see" basis and frequently failed. Such approaches prevail in many parts of the world. Yet it must be regarded as particularly serious in developing countries where weak economies could well do without the added strain of supporting inefficient systems or where failure can simply lead to going without. The author, in this book explains how today attitudes are changing. Whereas maintenance and rehabilitation used to lack glamour, and were o |
