A Preliminary Cellular Model for Sand Coastal Erosion and Experimental Contrast with Porto Cesareo Case
نویسندگان
چکیده
The phenomenon of sand erosion is recently spreading in Mediterranean beaches in a worrisome way. Cellular Automata modelling such a phenomenon involves many difficulties for adopting a convenient time and space scale (minute and decimeter), that can permit temporally reasonable simulations. A very preliminary model RUSICA was developed in association with an experimental work in order to test hypotheses, to receive suggestion separately for some basic processes and to learn from past occurred cases. During this contamination phase, some experimental applications were succesfully projected in order to contrast sand erosion on the coast. This paper presents the current initial version of RUSICA for sand erosion/transport/deposition and describes the results obtained at Porto Cesareo coast in the Italian Apulia Region. Complete simulations by RUSICA will soon follow this preparatory work.

An experimental study of the effect of silt and influence of cell confinement on the bearing capacity of circular footings on silty sand was carried out. Laboratory experiments on clean sand and sand containing silt up to 25 % were performed. Cells with different heights and diameters were used to confine the silty sand. The effect of proportion of silt in sand, cell diameter, cell height and t...
