Paper Abstract

A Landsat TM image of the Arno River mouth (Tuscany, Italy) was geocoded and atmospherically corrected in order to obtain suspended sediment concentration (s.s.c.) values. For the same day in which the image was a acquired, the river plume was simulated with MIKE 21 modeling system, given river discharge and wind speed. The suspended sediment concentration maps obtained through the two procedures were compared and eddy viscosity and dispersion coefficients were modified in order to gain the plume shape which best fits the remotely sensed one. After additional calibrations, the modeling system will be used to predict pollutant dispersion along the coast, which is intensively used for tourism.
