| Sumario: | The surface drainage of a mixed river basin (headwater on the Eastern edge of the Azul hills and middle and low areas on the Pampean plain) was simulated with two hydrological models, a lumped model and a grid model. This work presents the analysis and comparison of the results obtained from the simulation of some flood events. The lumped model used was HEC-HMS, from the U.S. Army Corps of Engineers. The distributed model was System of Simulation SSHH-I, from Rosario National University. For this last model, the digital elevation model (DEM) used was obtained using radar images interferometry techniques. Comparison between the models was made considering two aspects: i) discharge and volumes at the basin outlet; and ii) the capacity to represent the space distribution of water on the surface of the river basin, that is a critical factor for the floods in plain areas. The use of a grid DEM allowed a better representation of the surface movement of water and of storage areas, the being very common in this type of relief, characterized by a basically level morphology. |
