| Summary: | [EN] The main objective of this final project is improving the knowledge of the water resources in the Jucar river basin by obtaining the streamflow series in the basin. The series have been obtained in a daily scale and calibrated on a monthly basis. Moreover, a spatial scale is used and it allows to uphold the water resources in areas currently have not accurately assessed. The methodology has consisted in the development of rainfall-runoff (RR) models implemented in the EVALHID module (Assessment of water resources) developed by the Water Resources Group of the Universitat Politècnica de València and integrated into the Decision Support System (DSS) AQUATOOL. It was later analyzed how it affects the use of one or another streamflow time series in the management of water resources in the basin using SIMGES module, also included in the AQUATOOL DSS. The RR model development consists of different phases. First, climate data available is analyzed in order to obtain the precipitation and potential evapotranspiration time series which will be the model inputs. The HBV has been selected for each of the 94 sub-basins that make up the system model. For calibration has been employed an adaptation to Visual Basic applications of the SCE-UA algorithm (Shuffled Complex Evolution method developed at The University of Arizona) and the coupling algorithms Rosenbrock and Latin Hypercube (HLR). A comparative of the two algorithms listed above has been completed in the calibration process, being consistent with their results and efficiency. In conclusion, it is obtained that the HLR presents similar results to the SCE-UA but has a higher efficiency. Another comparative in which calibrations are made with a greater or lesser aggregation is performed. Comparing their results is determined that further disaggregation provides more realistic results. Once the results of the RR model are obtained, an analysis between the calculated series and the currently used in the Jucar management system are made. This analysis is performed between 1980 and 2007 and during the first half of the period, it shows that the availability of the resource is less than in the current series, while in the second half of the volume of resources is similar to that currently seen. These same results can be observed when the volumes stored by the three major reservoirs in the basin are compared |
