Ground‐Water Flow Patterns in Confined Aquifers and Pollution

Abstract

The authors have developed an analytical theory that enables one to prepare a flow net for an arbitrarily shaped, confined aquifer from which water is drawn by means of a well. A knowledge of the shape of the aquifer and the hydraulic head on the boundaries of the aquifer, which are not impervious, is required. Flow nets for a number of elliptical‐shaped confined aquifers, by which naturally occurring aquifers may be approximated, are presented.

Mathematical models for gully-wall and mineland-soil seep and slip

“…Stations 40 and 32, of the network, are located 10 meters upstream and 10 meters downstream from the discharge pipe from the ICPDM #1 sediment pond which is the only outlet for effluent from ICPDM #1. Some of the selected pH readings of the pond water and the above and below pond stations are shown in Table 5, The important point in the To solve the mathematical details of the seepage prob lem in mineland soil, reviewed works of many researchers like Powell and Kirkham (1976), Kirkham and Van der Ploeg (1974), Najmaii (1974), Warrick (1970), and others.
