Dam-reservoir interaction plays an important role in the seismic response of dams. In this paper, the Scaled Boundary Finite Element Method (SBFEM) put forward by Wolf and Song is used to evaluate the dynamic water pressure acting on the dam surface during earthquakes. The basic formulas are derived. This method combines the advantages of the Finite Element Method (FEM) and the Boundary Element Method (BEM). Only the dam-water interface needs to be discretized, the computational effort is reduced significantly. In addition, the Sommerfeld radiation condition at infinity is satisfied exactly. Numerical examples of gravity dams and arch dams show that this approach is simple, effective and appropriate for engineering purpose.
