In this paper, time-domain dynamic analysis of dam - infinite reservoir is studied. A numerical method, discrete singular convolution (DSC), which seems to be efficient and simple, has been used to model the mixed boundary conditions. After a brief introduction, DSC is applied to model the equation of motion of fluid-structure with constant cross section subjected to El-Centro (1940) earthquake. To show the accuracy and reliability of DSC method, the results have been compared with the Lee & Tsai method as a benchmark. The results show the competency of the proposed method to model Dam-Reservoir systems.
