TR-19 : Recharge from large depression storage

Abstract

The transient analysis of the groundwater flow around a lake of square cross section and having uniform depth has been analysed for a hypothetical setting of the boundaries (rivers on the lateral sides of the lake and no flow boundary at the ether two sides; both the boundaries being at the same distance from the lake) using a three dimensional finite difference model. Similarity approach has been employed to develop a type curve, which enables the assessment of the rate of recharge from the lake to groundwater reservoir, with the help of observed head change in an observation well situated anywhere within the influence area of the lake and vise-versa. Ideal location for an observation well has also been suggested.
