Soil and water conservation structures design
Soil and water are the fundamental components of the environmental continuum and hence of the ecological continuum. Their conservation is therefore vital which is accomplished by the employment of conservation measures. These measures can be either structural or non-structural or a combination thereof. Development and design of these measures depend on physiographic, hydrometeorological, and field conditions (soil, land use and land cover, and crops) as well as the availability of quality data. Complicating the design of these measures is climate change whose impact needs to be incorporated in the design.
Soil and water conservation is a vast discipline combining related aspects of soil and crop sciences, forestry, hydrology, hydraulics, hydrometeorology, irriga-tion, drainage, geotechnical engineering, environmental engineering, structural engi-neering, and decision science. There is a multitude of books and technical reports on soil and water conservation in both the field of soil science and agricultural engi-neering. Most of the books, however, focus more on concepts, principles, theories, and methods, but much less on design of measures and their implementation in field, and on their effectiveness and methods of their improvements in field. One conse-quence, especially in developing countries, is that field engineers or soil conserva-tionists base design of these measures on methods which are somewhat outdated and which do not take into account modern methods of design and the impact of global warming and climate change, land use land cover changes, changes in soil and crop management, and environmental impact assessment.
The book by Prof. Rajendra Singh is one of the few books that emphasise design of soil and water conservation structures and is very timely. Spanning 14 chap-ters it encompasses basic principles and procedures of soil and water conservation, mechanics of erosion, development of measures for the control of erosion, techniques for the measurement and modelling of soil loss, applications of remote sensing (RS) and Geographic Information Systems (GIS) to soil conservation, assessment of the impact of climate and land use land cover (LULC) changes on soil erosion, and design of soil and water conservation structures.
The book will be useful for graduate students, college faculty, field engineers, and watershed managers. I applaud Prof. Singh for writing this book which has long been much needed. The book reflects his long experience in teaching, research, consultancy, and extension.
