A STUDY ON DIRICHLET BOUNDARY CONDITION IN GROUNDWATER FLOW MODELLING

Abstract

In actual practice most of the water bodies are partially penetrating and as such horizontal flow models are not applicable. In the present study piezometric peak/trough in an aquifer bonded by partially penetrating water bodies is simulated by horizontal flow model employing reduced hydraulic conductivity across the boundary link. A series of numerical experiment were conducted and a relation is evolved which describe the dependence of the ratio of the reduced hydraulic conductivity to the regular hydraulic conductivity on degree of penetration and vertical anisotropy
