A 2D computational model is used for the hydrodynamic analyses of earthquake excited dam-reservoirs. The model is based on the finite volume solution of the Navier-Stokes equations considering compressibility effects due to sudden change in pressure field during earthquake. Volume of Fluid Method (VOF) is used to track the nonlinear free-surface waves in the reservoir. A non-reflecting boundary condition is applied at the outflow boundary to prevent the pressure and free-surface waves reflecting from the boundary back into the domain. Numerical results are compared with the existing semi-analytical solutions developed for dams with vertical and sloping upstream faces to demonstrate the capability of the computer code for the realistic simulation of earthquake excited dam-reservoirs.
