Modelação hidrológica da bacia internacional do Guadiana

20/05/2019

The Guadiana hydrographic basin is located in the Iberia peninsula presenting a dry temperate climate in almost all its extension with high risk of water scarcity in dry years. It is necessary for the management of the water resources to be aware of the needs that population, agriculture, industry and river ecology have when there is less water available. The environmental modeling is an indispensable tool for the water managers since it allows different climate trends and water consumptions to be analyzed in order to identify less resilient locations. The main objective of this work is to simulate the water dynamics by applying the MOHID-Land mathematical model in the Guadiana hydrological basin. By simulating the main processes of the water cycle that occur in the basin between 1979 and 2014, such as the surface runoff, the evapotranspiration, the water stored in the soil, in aquifer, and in reservoirs with capacity higher than 10 hm3. The calibration and validation of the model were done by analyzing several statistical parameters that compare the flows obtained in the simulation and the flows recorded in the hydrometric stations present along the basin. From the results of the calibration and validation of the model there were noticed differences between the hydrometric stations with and without reservoirs influence as well as a difference in the results obtained in the Portuguese and Spanish stations, with last one having higher drainage areas.
