Abstract

Seasonal to inter-annual variability of beach profiles has been investigated using a one dimensional beach profile model developed on the ‘reduced-physics’ modelling approach. The model uses a diffusion formulation as the governing equation and adopts an inverse modelling technique for solving the e...
