【 摘 要 】
The objective of the work presented herein is to quantitize dune erosion as a function of the awash mechanics. In order to achieve this aim, a numerical model is developed which solves the one dimensional continuity and momentum equations for depth and velocity of the swash at the face of the dune. These parameters are then used as input to the dune erosion model which predicts the e::tent of toe retreat of the dune as a function of time. Since the model is formulated in real time, both short and long term events may be simulated. This is particularly important in terms of understanding the short term event in which the dune and beach face do not achieve an equilibrium profile.
