This book presents systematic, integrated A-to-Z coverage of state-of-the-art unsaturated zone hydrology. Multi-disciplinary in approach, it provides both a soil physics and an engineering approach to unsaturated zone hydrology. Coverage begins with the basic physical properties and the behavior of clays, and moves on to contaminant transport and other parameters such as spatial variability, scaling, and fractals in the earth sciences. KEY TOPICS: Details analytical solutions for seven analytical infiltration models. Provides a comprehensive description and equations for performing a detailed water balance used to size and design water-storage facilities, reclamation zones for waste-storage facilities, and other water-management facilities. Presents five analytical models for both deterministic and probabilistic solutions to liquid/vapor flow in the unsaturated zone -- including unique coverage of the derivation and use of a three-dimensional analytical solution for flow of NAPLs in the unsaturated zone. Presents eight analytical models to assess unsaturated zone contaminant levels which are permissible to regulators for protection of underlying ground water. Includes a detailed description of the current technology of site characterization and monitoring devices used in unsaturated zone research -- including illustrations, diagrams of connections, and advantages and disadvantages of each. Illustrates real-world problems typical of sites the authors have worked with during the last 10 years. A reference for practicing engineers and environmental law firms.

Using a quantitative modeling approach, this volume offers a comprehensive exploration of the movement of water in the unsaturated zone (and associated transport phenomena) – the pathway of many contaminants to the saturated zone where much of the world's potable water is stored. It is the first book to combine research and knowledge on this subject from a wide variety of disciplines into a single source directed toward engineering and environmental training and applications. Deals with contaminant and heat transport in the unsaturated zone; includes a description of soils and their properties and unsaturated soil hydraulic properties; describes unsaturated zone processes; and thoroughly explores numerical modeling and uncertainty in modeling. A text for students in engineering and environmental science, and a reference for practicing engineers and scientists involved in the analysis of unsaturated zone contaminant problems.

Vadose Zone Hydrology describes the elements of the physical processes most often encountered by hydrogeologists and ground-water engineers in their vadose zone projects. It illustrates the application of soil physics to practical problems relevant to the characterization and monitoring of the vadose zone. It includes an introduction to physical processes, including basic flow theory, and provides examples of important field-scale processes that must be recognizable by hydrogeologists. Considerable attention is given to the concepts of recharge, including how it is most accurately evaluated in the vadose zone. Field and laboratory methods for characterizing hydraulic properties in the vadose zone are also covered, and case studies illustrating these methods are provided. New and emerging technologies for monitoring the vadose zone, particularly for the purpose of detecting contaminants, are highlighted. In the last section of the book, additional case studies are presented, demonstrating applications related to seepage detection, landfill monitoring, and soil gas investigations. This book is written from the perspective of hydrogeologists and is designed to be directly applicable and to maintain continuity and consistency between chapters. It will be an invaluable primer for environmental or geotechnical consultants, regulators, or students who have no prior formal academic training in unsaturated flow concepts. Because the text contains some of the latest advances in this field, it will be an excellent reference for geologists and engineers currently working on problems of vadose zone hydrology.

Mankind has manipulated the quantity and quality of soil water for millennia. Food production was massively increased through fertilization, irrigation and drainage. But malpractice also caused degradation of immense areas of once fertile land, rendering it totally unproductive for many generations. In populated areas, the pollutant load ever more often exceeds the soil’s capacity for buffering and retention, and large volumes of potable groundwater have been polluted or are threatened to be polluted in the foreseeable future. In the past decades, the role of soil water in climate patterns has been recognized but not yet fully understood. The soil-science community responded to this diversity of issues by developing numerical models to simulate the behavior of water and solutes in soils. These models helped improve our understanding of unsaturated-zone processes and develop sustainable land-management practices. Aimed at professional soil scientists, soil-water modelers, irrigation engineers etc., this book discusses our progress in soil-water modeling. Top scientists present case studies, overviews and analyses of strengths, weaknesses, opportunities and threats related to soil-water modeling. The contributions cover a wide range of spatial scales, and discuss fundamental aspects of unsaturated-zone modeling as well as issues related to the application of models to real-world problems.

The unsaturated zone is the medium through which pollutants move from the soil surface to groundwater. Polluting substances are subjected to complex physical, chemical and biological transformations while moving through the unsaturated zone and their displacement depends on the transport properties of the water-air porous medium system. Pollution caused by human activities, agriculture, and industry, has brought about a growing interest in the role of the unsaturated zone in groundwater pollution. Due to the complexity and the multidisciplinary nature of the subject, it is being investigated by specialists from various scientific disciplines, such as soil physicists, chemists, biologists, and environmental engineers. This state of affairs has motivated the initiative taken by the Water Quality Commissions of IUPAC (the International Union of Pure and Applied Chemistry) and IAHS (the International Association of Hydrological Sciences) to convene an international workshop, which was organized and hosted by the Institute of Soils and Water of the Agricultural Research Organization in Bet Dagan, Israel in March 1983. The lecturers at the workshop were an invited group of specialists who are engaged in studying the many facets of the unsaturated zone, and the present book is a selection of their presentations. Each chapter of the book relates to a different aspect of the unsaturated zone.

Das vorliegende Buch über Karsthydrographie und physische Speläologie ver bindet zwei Sachgebiete, die bisher getrennt behandelt worden sind. Beide Wissensgebiete sind ihre eigenen Wege gegangen, weniger aus sachlicher Ver schiedenheit, als wegen der unterschiedlichen Betrachtungsweise. In der Karst hydrographie steht die Beschreibung unterirdischer Gewässer mit ihrem physi kalischen und chemischen Verhalten im Mittelpunkt, in der physischen Speläo logie die unterirdischen Hohlräume mit ihrem Inhalt, die meist durch eben diese Wässer geschaffen worden sind. Diese Hohlräume lassen sich nur mit Hilfe karsthydrographischer Kenntnisse richtig interpretieren, geben aber daftir Hin weise auf das Verhalten der Karstgewässer. Karsthydrographie und physische Speläologie sind somit zwei Seiten des unterirdischen Karstphänomens und sollten unter einem einheitlichen Blickwinkel betrachtet werden. Das Buch wendet sich an Geologen, Hydrogeologen, Geomorphologen, Geographen und Karstforscher, vor allem Speläologen, sowie an alle Höhlen freunde, unter ihnen im besonderen die Laienforscher. Der Inhalt muß daher zwei Gruppen ansprechen, einerseits die akademisch Geschulten, seien es Hoch schuldozenten, Hochschulabsolventen oder noch Studenten, die in der Regel ausreichende Grundlagen zum Verständnis der theoretischen Ausführungen aufweisen, andererseits die Laien, die eine erlebte Anschauung aus den Höhlen mitbringen, doch häufJ.g nicht über alle wissenschaftlichen Grundlagen zum Verständnis der Phänomene verfügen. Deshalb mußten gelegentlich auch ein facheren Problemen größerer Raum gewährt und nomenklatorische Fragen mit einbezogen werden.
