"Dealing with water management concerns needs analyzing of diverse elements of hydrologic procedures taking place in the area of interest. As such procedures are happening in an integrated system that exists at a watershed level, thus the analysis must be carried out on a watershed basis. Understanding of relationship between a variety of watershed characteristics such as morphology, land use and soil, and hydrological mechanism is very essential for water resources development in any area. Since the hydrologic processes are very intricate, their proper understanding is essential. This volume Hydrology and the Management of Watersheds as its name indicates covers principles, methods, and applications of hydrology and watershed management. Important hydrologic concepts and methods are described in detail but primarily within the context of forested watersheds since most of the nation’s fresh water originates from forest lands. Water resource management and their delineation, importance, and variation are explained and illustrated. The book covers with updated chapters on the descriptions of different types of wetland systems and wetland watershed responses from different management actions in different regions. It provides an overview of the main challenges facing experimental watershed hydrology. Addressing these challenges will hopefully lead to substantial innovation in the field. It reviews currently available hydrologic and water quality models, and presents model application case studies, to provide a foundation for further model development and watershed assessment studies. The book is intended to provide fundamental hydrologic principles and practices about hydrology and the hydrologic cycle to allow citizens in watershed groups, students, educators, and policy makers to be more informed about water resources and their behavior and management.
