![]() ![]() ![]() The results of the model validation indicated that the model calculates the seepage discharge and uplift pressure with a maximum error of less than 3.79% and 3.25%, respectively. The model validation was performed using the measured data from experimental tests. In order to reach this goal, a numerical model has been developed in which the general equation of fluid flow in non-uniform anisotropic soil is solved by the finite volume method on a structured grid. Therefore, this study investigated the effect of the downhill and uphill impervious layer's slope (downhill/uphill foundation slopes) on the uplift pressure, seepage discharge and exit gradient under hydraulic structures. IDepartment of Water Engineering, PO Box 1158, Razi University, Kermanshah, IranĪlthough the impervious layer under a hydraulic structure is rarely flat, the effect of the impervious layer's slope, under the hydraulic structure, on seepage characteristics has not been studied to date.
