For model tests, the correct generation of the most realistic representation of the natural wave field is of greatest importance as the environmental conditions denote the starting point for all following analyses of any behaviour of a marine structure. Thus, it has to be defined first what “reality” is, followed by a thorough analysis of the inherent limitations of basin wave fields. Furthermore, all realistic aspects of the wave field have to be modelled at sufficient accuracy involving the wave maker control, flap geometries and appropriate analysis techniques. This paper gives an overview of the most recent developments in advanced basin wave modelling including a wide range of aspects as realistic wave spreading, deterministic wave generation, focusing waves, directional wave analysis, spurious waves and shallow water wave generation.
