Modeling Beach Morphology Changes Coupled to Incident Wave Climate and Low Frequency Currents

Abstract

This work is intended to provide a process-based model for predicting nearshore large scale bedform evolution over day to week time scales, as a first step to bridging the gap between short-time physical predictions and longer time (annual and longer) predictions based on parameterized physics. This gap is still immense, and will only be closed with (1) the advent of both faster computers and with (2) the ability to access local sediment transport formulations applied over reasonably long time scales. We are mainly concerned with the second aspect of this problem.
