Modeling aspects have added a new dimension in research innovations in all branches of engineering. In the field of soil and water engineering, they are increasingly used for planning, development, and management of land and water resources, including analysis of quantity and quality parameters of surface and ground water, flood forecasting and control measures, optimum allocation and utilization of irrigation water. The application of these models saves considerable time in decision support systems and helps in conservation and optimum allocations of scarce precious natural resources.

The lingo of soil science is a language unto itself. Soil and Environmental Science Dictionary is a glossary of terms used in soil and environmental science, including terms from related disciplines. Designed for teachers, students, researchers and others interested or involved in environmental sciences related to soils, this compilation includes a

This book presents a rigorous mathematical development of soil water and contaminant flow in variably saturated and saturated soils. Analytical and numerical methods are balanced: computer programs, among them MathCad and Fortran, are presented, and more than 150 practice and discussion questions are included. Students are thus exposed not only to theory but also to an array of solutions techniques. Those using the book as a reference will appreciate the careful development of basic flow equations, the inclusion of solutions and methodology currently available only in journals and proceedings volumes, and the examples and calculations directly applicable to their own work.

As in the first and second editions, this elementary textbook on soil and water engineering has been written primarily for classroom and laboratory instruction at the college level for students in agriculture and in related non-engineering fields. The purpose of the book is to present up-to-date information that has been gathered through experience and research in a form that will be useful for the beginning student of this subject. The engineering phases of soil and water conservation are emphasized, but the authors have realized that all aspects of these problems must be considered, including agronomic, economic and others.

Book is written in easy english language. It is useful for degree and diploma students of Agricultural Engineering and those working in this field.CONTENTSIntroduction H Rainfall and Runoff relationship H Soil erosion principles H Gully erosion H Design of permanent gully control structures H Stream bank erosion H Wind erosion H Erosivity and Erodibility H Prerequisites for soil and water conservation measures H Argonomical Practices to control Soil Erosion H Terracing H Bunding H Grassed Waterways and Diversions H Water harvesting H Farm ponds H Earthen Dam H Retaining wall H Culverts H Soil loss estimation-models H Land use capability classification H Sedimentation H Reservoir sedimentation H Grassland farming H Watershed Concept and Management H Glossary H Question Bank H Appendices H Bibliography H Subject Index.
