This research was supported in part by the Russian Foundation for Basic Research under grants 01-05-64704, 00-07-90343, and 00-15-99092; the GNFM of the Italian INdAM; UNESCO under contracts UVO-ROSTE 875.629.9 and 875.704.0; and CASPUR-Rome. An algorithm for simultaneous determination of two coefficients in an inverse problem for equations of parabolic type is studied. The model under investigation was proposed by de Vriend et al. to describe the long-term coastal profile evolution. The iterative inversion procedure is based on minimization of an appropriate cost functional. Results of numerical tests are presented to illustrate the performance of the algorithm. A file of real measured data on the coastal profile evolution was processed numerically to validate the aforementioned diffusion-type model.
