Abstract
Diffusion model is considered to describe coastal depth profile. For model calibration an inverse problem for equation coefficient reconstruction was solved by minimization of a certain misfit functional using an extra boundary conditions. Multy-dimensional optimization was arranged with the help of differential evolution method. Finite elements method was used to calculate model depth profile. The JARKUS dataset was used for testing at different temporal and spatial intervals. Relative error at the level of 5 % was achieved.
