The management of the groundwater resources is a challenging task worldwide against the backdrop of the growing water demand for various sectors and shrinking resources. Moreover, this task has been hampered significantly due to declining/rising groundwater levels and associated contamination. A broad range of solutions could be considered to address the aforementioned problems of groundwater management, but the effectiveness of all the solutions and their combinations cannot be verified with field experiments. Given their predictive capability, simulation models are often the only viable means of providing input to management decisions, as they can forecast the likely impacts of a particular water management strategy. This book presents a comprehensive appraisal on the simulation modeling applications for the management of groundwater resources. The book will be of great value to hydrologists, agricultural engineers, irrigation engineers, and civil engineers concerned with groundwater management.
