The prediction of beach changes due to alongshore wave induced sediment transport has traditionally been made using physical modelling techniques. However, apart from the problems of scaling, physical models are generally too small to reproduce sufficiently long stretches of coast. With the recent development of mathematical models most problems dealing with beach plan shape changes are now dealt with numerically. Models dealing with sand beaches already exist and are used extensively at the Hydraulics Research Station to predict chancres in coastline evaluation brought about by construction of harbour arms, artificial headlands, etc. Our view is that a relatively simple model is also needed which will allow the coastal engineer to predict the long-term changes of a shingle beach. Such a model clearly will not be able to incorporate short term fluctuations due to variations in the wave climate or due to extreme events. Nevertheless it should predict the mean annual rates of alongshore drift and of beach recession and advance.
