The book focuses on two issues related to mathematical and numerical modelling of flow in unsaturated porous media. In the first part numerical solution of the governing equations is discussed, with particular emphasis on the spatial discretization of highly nonlinear permeability coefficient. The second part deals with large scale flow in heterogeneous porous media of binary structure. Upscaled models are developed and it is shown that the presence of material heterogeneities may give rise to additional non-equilibrium terms in the governing equations or to hysteresis in the averaged constitutive relationships.

This volume brings together the systematic theme of physical hydrology while maintaining a link with the original book which emphasised the benefit of the study of water being considered in the widest sense within the physical and social environments.
Originally published in 1965 and with a second edition in 1970. Building upon the original two Madingley Hall seminars for teachers of non-university geography in 1965, this book presents an updated research picture of the 1970 transatlantic perspective. Answering the questions "What is happening in geography" and "What impact does this have on school geography", this provided a real link for students who were then making the increasingly difficult transition from school to university geography. Originally receiving a hostile reaction from British journals, the book's diagnosis and prognosis were a forerunner of developments in methodological changes of the discipline. This work collects a series of essays delineating geographic concepts in terms of the philosophic underpinnings, assessment of the geomorphic system, climatology, and social economic and historical changing trends. Techniques are reviewed including quantitative methods for geomorphology and social geography, fieldwork both in urban areas and land-use surveys, and finally in physical planning. Final analyses examine and contrast the teaching methods and courses in American and British High Schools, Colleges and Universities.
Originally published in 1973. This collection of essays looks at the 'quantitative revolution' and the 'new geography' by some of the geographers who had a significant part in those innovations and looks ahead to further developments. The views in the chapters are diverse and offer a fascinating glimpse of the discipline of geography as the subject was undergoing such change and becoming more socially committed. They cover theory, spatial-systems theory, forecasting, human ecology and climatology alongside the teaching of the subject. The concerns of the contemporary geographer come across and are of interest today as these areas have developed still more.

Water utilities are the main instrument for countries to achieve universal service coverage. In pursuing universal service coverage, water utilities have turned to pro-poor water services to extend water services in low-income areas. This thesis discusses the use of pro-poor water services by water utilities in Kenya, with the intention of highlighting the dimensions of the approach that require attention of policy makers and practitioners when engaging with the concept. Based on the analysis of the technologies, financial and organisational arrangements associated with the pro-poor concept, this thesis shows that the use of pro-poor strategies allows water utilities to reduce the risks of servicing low-income areas while still claiming to fulfil their mandate of providing access to all in a commercially viable manner. The analysis also shows that rather than a decision of the water utility, the choice for pro-poor strategies emerges as the result of a consensus or compromise between the different actors that constitute the broader institutional environment in which water utilities operate. The thesis concludes that while pro-poor water services may serve the interests of water utilities and other stakeholders, in the absence of well-directed subsidies and proper monitoring they will not result in low-income households benefiting from more affordable and reliable access to water.

Membranes are an energy efficient separation technology that are now the basis for many water treatment and food processing applications. However, there is the potential to improve the operating performance of these separations and to extend the application of membranes to energy production, gas separations, organic solvent-based separations, and biomedical applications through novel membrane materials. This book contains 20 chapters written by leading academic researchers on membrane fabrication and modification techniques and provides a comprehensive overview on the recent developments of membrane technology. Membranes can be manufactured from a range of materials including polymeric compounds, and ceramic materials, and both these materials are considered in the book. There are 5 chapters on water and wastewater membranes that cover the fabrication of thin film (TFC) composite membranes for nanofiltration(NF)/reverse osmosis (RO)/forward osmosis (FO) applications, stimuli responsive membranes, electrospun membranes, porous ceramic membranes, and polymeric ultrafiltration (UF) manufacture and modification. There are another 6 chapters on gas separation that consider carbon membranes, zeolite membranes, silica template and metal oxide silica membranes, TFC membranes, silica membranes, and metal organic framework (MOF) membranes. Zeolite membranes are also considered for organic solvent applications, as are solvent-resistant membranes manufactured by phase inversion, ceramic-supported composite membranes, and ceramic NF membranes. The emerging areas of membranes for energy and biomedical applications have 3 and 2 chapters, respectively. Energy applications consider ion exchange membranes for use in fuel cells, membranes for electrodialysis, and membranes for use in microbial fuel cells. For biomedical applications the chapters focus on hemodialysis membranes and redox responsive membranes.

Qanat is a gently sloping subterranean canal, which taps a water-bearing zone at a higher elevation than cultivated lands. A qanat consist of a series of vertical shafts in sloping ground, interconnected at the bottom by a tunnel with a gradient flatter than that of the ground. From the air, this system looks like a line of anthills leading from the foothills across the desert to the greenery of an irrigated settlement. Qanat engages a variety of knowledge and its studying entails an interdisciplinary approach. In a traditional realm, qanats are embraced by a socio-economic system which guarantees their sustainability. The facets of this socio-economic system operate closely together and make it possible for the qanats to remain into future. Veins of the Desert shows that digging a qanat requires a variety of sciences and technologies, though at a glance qanat is just a horizontal tunnel which drains out groundwater. Qanat is a feat of technology left from our ancestors; hidden underground, but its technical importance is apparent, not less valuable than such surface structures as bridges, castles, towers, etc. Qanat enjoys extended structures and sometimes its length reaches tens of kilometers. It passes through geological formations and faces different conditions and obstacles, so the qanat masters' efforts to solve these problems led to the accumulation of knowledge in terms of qanat construction over time, which has been handed down from generation to generation. Qanat is one of the most complicated traditional technologies, which require knowledge on nature ranging from groundwater to management. This indigenous technology used to bring water efficiently from tens of kilometers away to the thirsty lands. This book also gives insight into cultural and social heritages, which have crystalized around this technique. This cultural heritage still influences social life of the people living in such regions as central plateau of Iran where qanat has been the only means of supplying water. This technology is the focal point of the genesis of a particular civilization in the arid and semi-arid regions of Iran. The harsh environment drove those people to invent the technology of qanat and the know-how revolving around it. Qanat carries a tradition of science and technology which used to be practiced in order to overcome the technical obstacles in qanat construction. Thus, qanat is not only an irrigational means, but it should be seen as a technical and cultural legacy which deserves more attention. This book is a small encyclopedia on qanat system, providing the readers with easy answers to their questions about different aspects of this ancient technology.
Karstified rocks of different lithology cover more than 10% of the continental surface of our planet. It is known that some 20% or even a few percent more of the global population largely depends on karstic groundwater but in many karst areas all over the world there are limited natural resources including absence of drinking waters. The problems of water shortage, equitable water use or water protection from pollution, become more problematic when they come to transboundary regions. The Dinaric region is a classical karst area where created borders of newly established countries after the civil war in 1990s resulted with an urgent need to create ambience for sustainable water management. The project DIKTAS is one of the first ever attempts to establish sustainable integrated management principles in a transboundary karst aquifer of the magnitude of the Dinaric Karst System. This volume presents selected papers from the conference held in June 2014 in Trebinje, Bosnia & Herzegovina including presentations of some of the project's achievements but also number of other research results conducted in karst environments worldwide.
An important part of the risk management of natural hazards in mountain regions concerns the hazard assessment and the planning of protection measures in steep headwater catchments, i.e. torrent control and slope stabilization. Torrent processes in steep channels have their rightful place among the various alpine natural hazards and the corresponding control measures have a long tradition in the European alpine countries. In the planning and execution of such measures, professional experience has been of paramount importance. This experience was based primarily on observations made during and after hazardous events, as well as on regular field visits in the catchments of a steep headwater stream. Quantitative measurements, e.g. of the discharge and of the eroded and deposited solid materials, have been increasingly carried out only in the last decades. This set the basis to develop and improve quantitative methods to predict flow hydraulics, bedload transport and debris flows in torrent catchments. This publication presents an overview of methods to quantify channel processes in steep catchments. The understanding and the quantitative description of channel processes provides an essential basis for the planning of protection measures.
