"Design and evaluation of hydraulic structures requires and understanding of the interaction between the flow and the components of the structure. The non-hydrostatic forces generated by the flowing water are of particular interest. Historically, physical models have been the primary means for predicting hydrodynamic forces on hydraulic structures. Laboratory studies of hydraulic loadings require relatively large-scale physical models which are expensive to construct, instrument, and operate. The hydraulic evaluation costs can be decreased if computational methods are used in lieu of such physical models studies. Numerical models capable of calculating hydraulic loads on bridge piers, lock guard walls, culvert valves, tainter valves, floodwalls, and moored ships will result in more cost-effective structural, mechanical, and geotechnical designs."[1]
