An analytic element solution to unconfined flow near partially penetratingwells

An analytic element solution for steady-state unconfined flow near one or m ore partially penetrating wells in an ambient flow field has been developed . The phreatic surface is modeled using a three-dimensional version of the Zhukovski function. Boundary conditions at control points on the phreatic s urface and seepage face at the well are maintained by use of distributed si ngularities outside the how domain. The phreatic surface and seepage face f or a single well is compared with two different numerical solutions acid a laboratory experiment found in the literature. A sample case showing flow n ear two wells in an ambient flow field is presented. (C) 1999 Elsevier Scie nce B.V. All rights reserved.
