Watershed Planning and Management examines the science, technology, and practice of managing land and water resources through the watershed approach. It integrates hydrology, geomorphology, soil and water conservation, land use planning, socio-economic considerations, and modern tools such as remote sensing and GIS. The book presents an overview of global water resources, followed by fundamental concepts of watersheds, hydrological cycles, and delineation methods. With a balance of theory, methodology, and practice, the book serves as a valuable resource for students, researchers, practitioners, and policymakers. It not only strengthens conceptual understanding but also provides practical insights into implementing watershed projects in diverse geographic regions.
