Abstract: Procedures and analysis techniques for pre-processing physical data sets in preparation for performing a numerical shoreline change simulation study using the GENESIS model are presented. Major emphasis is given to the processing of input wave conditions, particularly the transformation of deepwater wave hindcast estimates to nearshore wave conditions for input to the shoreline change model. The paper presents a methodical analysis in which the level of detail and complexity increase with each step. Byproducts of the procedures include guidance for the development of a regional potential longshore transport sediment budget and estimates of net and gross transport based on expected variability of the input data streams.
