| Sumario: | [EN] This final work of master is about the hydrological modelling at a monthly scale of the Gallego-Cinca water resources system with an area of 12208 Km² of the Ebro river basin agency using the HBV rainfall-runoff model developed by the Swedish Meteorological and Hydrological Institute (SMHI). The software used is the RS-Minerve developed by the Centre de Recherche sur l¿Environnement Alpin (CREALP) and the engineering office HydroCosmos SA with the collaboration of the Polytechnic University of Valencia (UPV) and the Swiss Federal Institute of Technology in Lausanne (EPFL), is a program for the simulation and propagation of the surface runoff, capable of model complex hydraulic and hydrological networks according to a semi-distributed conceptual scheme. First the modelling of 2 subsystems (Gallego 4008 Km² and Cinca 8080 Km²) is performed, by the subdivision of each one in different smaller subbasins to make the hydrological modelling of each one of these taking into account the historical meteorological data, besides gauging stations belonging to the official network of gauging stations (R.O.E.A) present in the study area and the values of the water demand registered in a management model of the Aquatool software previously developed by the Ebro river basin agency were used, with which making a contrast of the simulation that provides the RS-Minerve software and the observed data through the years by those gauging stations, allowing to make the calibrations of the HBV model parameters of each subbasin in order to obtain simulations according to the reality with the help of some efficiency criteria and an objective function stipulated. Having calibrated the subbasin the next step was make the validation in other different period of the obtained calibration, thus finally the characterization of the subbasins, basins and the water resources system itself was achieved, achieving with this study and evaluate the behavior of the water resources, surface, subsurface and groundwater flows and influence of reservoirs present in the study area, obtaining then a parameterized model capable of reproducing any type of event in the water resources system with other input data different to those used in the calibration process. A correct calibration and a general parameterization of the hydrological model was achieved, getting good results and at the same time was found a clear alteration of the natural flow regime in the water resources system, first of all because of the large number of agricultural areas where the most of them are located in the subsystem of the Cinca river and second to the amount of existing reservoirs located almost entirely in the subsystem of the Gállego river producing considerable flow regulations. Finally different comparisons were realized between the contributions in natural regime of the SIMPA model registered in the management model of Aquatool and the obtained from the calibrated HBV model. To determine the goodness of the first one because is a more general model and the used in this work has a higher detail level. Evidencing that the ones from the SIMPA model are usually higher than those of HBV, and also respect to a typical year the naturally generated contributions are being overestimated from October to June and underestimated from July to September when the SIMPA model is used. |
