Abstract
The rate of seepage from a disposal field to a water supply source is dependent upon soil parameters and hydraulic conditions. Until the development of the high speed digital computer, the solution of the problem of superimposing an infiltration area on groundwater flow was too complicated by analytical and graphical methods. Therefore a computer program based upon the finite element principle was developed to solve the problem of groundwater seepage toward a well with vertical infiltration from the ground surface. The computer solution was verified by model study. (Author)
