STUDY OF BEHAVIOUR OF WELLS IN LEAKY AQUIFERS

Abstract

Ground water development dates from ancient time, for meeting the needs of irrigation and domestic water supply. Ground water development presents special problems. The lack of scie-ntific solutions to these problems, have, in the past, contributed to the mystery that surrounded ground-water development and the limited use to which ground water has been put. The proper development and management of ground water resources requires a knowledge of the extent of storage, the rate of discharge from and recharge to underground reservoirs, and the use of economical means of extraction. It may be necessary to devi$e artificial means of recharging these ground water reservoirs where no natural recharge sources exist or to supplement these sources. Research has, in recent years, considerably increased our know-ledge of the processes involved in the origin and movement of ground water and has provided us with better methods of development and conservation of ground water supplies. Evidence of this increased knowledge is to be found in the greater emphasis being placed on ground water development. It is, therefore, useful to have a proper understanding of the physical principles of ground water movement, behaviour of individual wells and group of wells. Quite a large number of publications are available on behaviour of wells in confined and unconfined aquifers, but similar inform-ation for leaky aquifers is not available in consolidated form. This Dissertation is an attempt to meet this objective........
