| Abstract: | A deterministic combination of a numerical and a physical model for wave flumes is presented. In the combined model, a Boussinesq model (MIKE 21 BW) is chosen for the numerical calculation. A wave flume with a piston type wavemaker and the Active Wave Absorption Control System (DHI AWACS) is utilized for the physical model. The link between the numerical and physical models is made by an ad hoc unified wave generation theory, which is deviscd in the paper. This theory accounts for shallow water nonlinearity and compensates for local wave phenomena (evanescent modes) near the wavemaker. |
