Numerical and experimental analysis of seepage beneath a model of a gravity dam

For a steady flow condition beneath a physical model of a typical gravity dam, a comparative analysis between the measured flow data and the one predicted by numerical analysis is presented. The velocity vector field is compared qualitatively and the pressure field is compared quantitatively (on a relevant sections of the flow domain). The numerical analysis is performed by solving the Laplace differential equation by finite difference method. Finally, a particular interest is dedicated to a velocity field and the process of local erosion.
