Abstract The finite element method is nowadays the standard method for solving partial differential equations, especially in continuum mechanics. In this chapter the fluid, solid and interface elements are derived. The elements are employed for the discretization of the nearfield, that is the dam, the nearfield of the foundation and the nearfield of the reservoir. For the farfield, a semi-analytical approach is taken. The cross-section of the infinite channel is discretized by finite elements, whereas the infinite direction is described analytically. The farfield solution is developed in the frequency domain and the coupling to the nearfield is discussed. In the last part, the frequency-domain analysis is applied to an arch dam. Besides the rigorous solution also some simplified models are analyzed for comparison.
