Saturated and unsaturated flow of ground water to a regular horizontal drain system in nonhomogeneous layered soils

Abstract

The paper presents a mathematical formulation of the problem of drainage of nonhomogeneous soil by a regular system of horizontal drains in the framework of hydrodynamic and hydraulic theories. Algorithms for approximate solution of the problem are described. Comparison of numerical and analytical solutions substantiates the theoretical depen&'nces.The paper analyzes numerical results obtained for moisture transport processes in a saturated/unsaturated porous medium with a regular system of horizontal drains under the action of pressure, gravity, and sorption.
