Abstract
A previous model for nearshore orthogonal gradients (Hardisty, 1986) was based upon a simple bedload function and identified feedback relationships between the equilibrium seabed gradient and wave induced flow asymmetry. That model is developed here with the inclusion of suspended load transport, first order shoaling transformations, second order wave induced flows, and a measure of the sediment grain size. The results are compared with some of the general features of prototype geomorphologies.
