Dupuit-Forchheimer solutions for radial flow with linearly varying hydraulic conductivity or thickness of aquifer

摘要: [1] This paper presents new analytical solutions for steady state piezometric heads in phreatic and confined aquifers with radial flow. The utilize two constant head boundaries a hydraulic conductivity k or thickness of aquifer H that is linear function radius r. Previous applied H, they were usually based on one boundary, which might be superimposed solution allowed discharge recharge at the center aquifer. previous may difficult to apply real because an oversimplification nature. Dupuit-Forchheimer assumption implies vertical gradients are ignored. magnitude error introduced by allowing = H(r) evaluated numerically this paper.
