About this book
Arguably the first book devoted entirely to examining this important resource, Wadi Hydrology presents up-to-date methodologies required for sustainable management of wadis and their water resources. Through unique physical approaches, field cases, sample interpretations, and various applications to different models, this book provides an in-depth understanding of these systems that illustrates the efficiency of harnessing water from wadis. The author compiles the most up-to-date information on arid region hydrology, including specific techniques for hydrological calculations and desertification assessments and includes examples and solved problems in each chapter.
