An algorithm for the study of the shallow water equations has been presented in many papers and applied to the field data of the Venice lagoon. The interest for an adaptive procedure is evident in all the problems of CFD; here we consider the shallow water problem and a model is developed to introduce the adaptive procedure for studying with greater precision some local phenomena of critical behaviour without an excessive growth in the number of nodes, in the amount of work done a-priori and in general in the complexity of the calculations. Some numerical results of the application to the Venice lagoon are presented.

Abstract
An algorithm for the study of the shallow water equations has been presented in many papers and applied to the field data of the Venice lagoon. The interest for an adaptive procedure is evident in all the problems of CFD; here we consider the shallow water problem and a model is developed to introduce the adaptive procedure for studying with greater precision some local phenomena of critical behaviour without an excessive growth in the number of nodes, in the amount of work done a-priori and in general in the complexity of the calculations. Some numerical results of the application to the Venice lagoon are presented.
