| Sumario: | The implementation and preliminary calibration of a distributed, hydrological-hydraulic, physically based model of surface runoff on the Pavón basin (south of Santa Fe province) is presented. The basin has an area of approximately 3143 km2 and its main course is the San Urbano Channel- Sauce Stream and Pavón stream. The discharge is in the Paraná River. The information from topographic charts of the National Geographic Institute (IGN) was used, with aggregation in 150 m x 150 m grid size cells, as a digital terrain model. Additionally, information about the course network was available from topographic maps of the IGN, Google Earth © images; field trips and existing projects. The model was constituted with 139717 cells and a network of courses of 895 km and was preliminarily calibrated with hydrological and hydraulic information of an extraordinary event that occurred on January 15, 2017. The exploitation of the model, in this first level of advancement, allowed to realize the delimitation of flooded areas in the basin; the determination of areas with risk to human lives and maps of water permanence for the extraordinary event and a series of hypothetical events of different recurrences. These results are a contribution in the territorial planning of water resources in the study area. Although a severe information deficit is evident, the first results obtained in the rainwater flow and surface runoff propagation are acceptable. |
