| Resumo: | [EN] The purpose of the study is the water resources evaluation in the Jalon river basin, with 9718 km2, and the study of the behaviour of the Jalon system subbasins, one of the most important tributaries of the Ebro river. For this goal, a semi-distributed rainfall-runoff model has been developed, in order to evaluate the effects produced over the studio basin based on the hydrological response of each hydrographic subbasin of the system.The employed model has been HBV, conceptual semi-distributed model developed by the Meteorological and Hydrological Institute of Sweden. It allows hydrological modelling with a small number of parameters, showing versatility and flexibility in several applications. The tool that has been employed in the model, is RS Minerve 2.0, developed by CREALP and Hidrocosmos SA, in collaboration with Polytechnic University of Valencia. This software simulates rainfall-runoff processes, being based on object-oriented programming, resulting in hydrological and hydraulic modeling by reference to a semi-distributed conceptual scheme focused, on this case, in the Jalón river basin. The model development, both in calibration and validation processes, has been possible thanks to the historical series of data, registered by the gauge stations located in the basin, obtained form the Gauge Stations Official Network (R.O.E.A.), while data such as demands, reservoir monitoring, etc., has been obtained from a managament system (SIMGES) previously created and used by the Ebro Hydrographic Confederation (CHE). Meteorological data (inputs to the model), Spain0s v2.1 database has been used, developed by the Applied Mathematics department, University of Santander's Meteorology Group and the State Meteorological Agency. This database contains a 50 years network of rainfall and temperature data valid for all Spanish Peninsula and the Balearic Islands. After the model generation, it was studied the behaviour of each one of the subbasins, according to the processes that are carried out on the surface such as direct runoff, groundwater flows due to infiltration, as well as flow reduction due to regulation structures such as reservoirs and the influence that vegetation cover presents in the process. Finally, it is remarkable the contributions generated by the model, as vorrectly validated, could be really useful in upcoming jobs in hydrologic planning and management, ecological flow management, demands guarantees estimations, etc. This contributions have been compared with natural regime SIMPA model, developed by the Center for Studies and Experimentation of Public Works (CEDEX) and used by the CHE, in order to estimate whether they are overestimating or underestimating the contributions, trying to find possible mistakes which they may be done. |
