This chapter presents an analysis of the hydrological behavior of Sauce Chico and Napostá Grande rivers in the lower part of their watersheds, particularly at their mouths, and the relationship between their flowrates and rainfall events. In addition, both their incidence on and their interaction with  the hydrodynamics of the marine environment in the inner area of Bahía Blanca estuary are evaluated. It is shown how a significant flowrate increase produced by one storm event of a single exceptional rainfall affects this section of the estuary. To this purpose a preliminary hydrodynamic model based on the MOHID Water Modelling System has been developed.
