Abstract
The constant boundary element method is used to assess the effect of the location of a transmitting boundary on seismic hydrodynamic pressures in a water reservoir. A 2D mathematical model of a dam-reservoir-foundation system is used. The results indicate that the geometry of the finite part of the reservoir is a governing factor of hydrodynamic pressures acting on dams, where the location of the transmitting boundary changes the geometry of that part. For almost rectangular reservoirs the BEM results are less dependent on the location. Additional factors evaluated are the number of elements and the length of the element with respect to the induced shortest wave length in the reservoir.
