The technological advances of recent years include the emergence of new remote sensing and geographic information systems that are invaluable for the study of wetlands, agricultural land, and land use change. Students, hydrologists, and environmental engineers are searching for a comprehensive hydrogeologic overview that supplements information on hydrologic processes with data on these new information technology tools. Environmental Hydrology, Second Edition builds upon the foundation of the bestselling first edition by providing a qualitative understanding of hydrologic processes while introducing new methods for quantifying hydrologic parameters and processes. Written by authors with extensive multidisciplinary experience, the text first discusses the components of the hydrologic cycle, then follows with chapters on precipitation, stream processes, human impacts, new information system applications, and numerous other methods and strategies. By updating this thorough text with the newest analytical tools and measurement methodologies in the field, the authors provide an ideal reference for students and professionals in environmental science, hydrology, soil science, geology, ecological engineering, and countless other environmental fields.

Horse Pasture Management, Second Edition provides updated coverage on strategies for managing behavior, grouping, environments and feeding needs of grazing horses. Sections cover the structure, function and identification of forages, continuing into nutritional value of pasture plants. Management of soil, the function of a pasture ecosystem and management of plants in a pasture is covered next, followed by forage yield determination, horse grazing behavior, feed choices of horses, management of grazing horses, and how to calculate how many horses should be grazing relative to land size. Advantages of grazing more than one species of animal are described. Management of hay and silage are included since year-round grazing is not possible on many horse farms. Several chapters deal with interactions of a horse farm with the environment, including climate and weather and other living things. The book also covers strategies for managing manure, erosion, and water quality. It is ideal for researchers, scientists and students involved in animal science, specifically equine studies. Agriculturists, equine managers and veterinarians will also find this book useful. - Includes information on environmental best practices, plant and soil assessments, and wildlife concerns - Features a new section on reducing carbon emissions and increasing sustainability on horse farms - Explains pasture-related diseases, weed management and toxic plants to avoid - Recommends relevant published resources and extension programs

Global drylands, covering over 40% of Earth’s land surface, are important among worldwide ecoregions and support large human and livestock populations. However, these ecologically sensitive ecoregions are undergoing a rapid transformation resulting from climate change, socioeconomic and political factors, increases in population, and ever-growing demands for goods and services. Managing Soil Drought addresses basic processes and provides specific case studies throughout covering the protection, restoration, and sustainable management goals of global drylands under changing and harsh climatic conditions, including fragile and vulnerable ecosystems. The book is written by numerous researchers, academicians, practitioners, advocates, land managers, and policymakers involved in bringing about transformation in these regions important to human and nature. It includes information on basic strategies of sustainable management of global drylands aimed at improving water use efficiency through choosing appropriate species, developing new varieties, using organic and inorganic amendments, and scaling up innovative farming systems. This volume in the Advances in Soil Sciences series is an essential read for development organizations and policymakers involved in improving crop productivity and sustainability in drought-prone regions; students, researchers, and academicians interested in sustainable management of water resources; and those involved in emerging concepts of regenerative agriculture, agroecology, and conservation agriculture.

The papers collected in this book were given and discussed at the symposium on "Soil water physics and technology", which was held in Rehovot, Israel, from August 19th-September 4th, 1971. It was sponsored by the International Society of Soil Science (1.S.S.S.) through its Commissions I (soil physics) and VI (soil technology), and organized by the Israeli Soil Science Society. Thanks are due to the Editors for having assembled contributions and discussion remarks into a well-rounded, coherent book. The subjects covered in this book are the theoretical and practical aspects of the following topics: water movement in soils, soil-water interactions, evaporation from soil and plants, water requirements of crops, ion activity and migration in soils, soilwater management and salinity. In as much as these contributions were not solicited, they represent ideas and subjects considered important by the authors and debators. In science, one often finds a gap between basic research and practical application. If reading this book creates a feeling of an apparent lack of balance between theory and practice, this represents the state of our science today, and the thoughtful reader can and will recognize that much remains to be done.

Salt effects on water movement in usaturated Yolo loam soil are explored by comparing soil-water diffusivity values determined by Bruce and Klute's method in soil columns treated with SAR values 0,5 and 15 and wetted with water containing 15, 5, 2 and 0 me/l. Sorptivity values for these conditions are also compared. Total soil solution concentration estimated by electrical conductivity measurements and NA and CA concentrations measured by flame photometry are discused. Salt effects on soil-water diffusivity were more pronounced at larger values of water content. Movement of water in Ca-saturated samples was significantly affected only when the soil solution concentration was smaller than approximately 2 me/l. Soil samples treated with SAR 5 presented reductions in soil-water diffusivity when the solution concentration was equal to or smaller than approximately 3,5 me/l and the water content larger than 0,35 cm3/cm3. The soil-water diffusivity was also affected when the solution concentration was equal to or smaller than approximately 2 me/l and the water content larger then 0,30 cm3/cm3. Soil-water diffusivity of samples treated with SAR 15 was affected basically at all values of water content when the soil solution concentration was equal to or smaller than approximately 3,5 me/l. When such concentration was a large as 5 me/l, reductions in soil-water diffusivity were apparent only for water contents larger than 0,25 cm3/cm3. Chemical analyses of soil solution after infiltration revelated that most soluble salts in the soil column were carried near the wetting front. Significant displacement of Na by Ca occurred in soils treated with SAR 5 and 15. Although Bruce and Klute's method does not apply for chemically unstable and swelling soils, the slope of the plot of distance to the wetting front versus square root of time fitted the Boltzman variable for the water content of wetting front satisfactorily. This fact suggests good reliabillity of reported soil-water diffusivity values.
