This book focuses on natural and manmade structures which are used for drawing groundwater to the surface. Groundwater extraction structures include open dug wells (small-diameter open wells and large-diameter irrigation wells), tube wells, filter point wells, bore wells, surangams, and dug-cum-bore wells. Early abstraction structures were mainly natural but more manmade structures are now in use due to technological developments. Upto 30% of the freshwater supply in the world comes from groundwater, and among freshwater resources, groundwater plays a crucial role in the drinking water supply. Due to rapid population growth, increased urbanization, changing lifestyles, industrial growth, and agricultural methods, the demand for groundwater continues to increase. The book will be of interest to faculty and students of geology, geography and civil engineering, research scholars, hydrogeologists, planners, and professionals in the field of groundwater.
