Abstract

The theoretical framework of a 1-D model of wave and current interaction in nearshore regions is described in this paper, along with comparisons with laboratory and field data. The theory of wave and current action is based on general mass, energy and momentum equations, applicable inside and outside the surf zone. An important feature is the modelling of tidal currents as well as wave-induced currents, with full interaction between the two types of current and the waves. The model is very efficient computationally and can process large quantities of input wave and tidal data (typically tens or hundreds of thousands of values), making it suitable for the investigation of long-term processes on beaches or in nearshore regions. The model is desgined to be used in conjunction with an appropriate sediment transport routine for problems concerned with the longshore movement of sediment.
