| Sumario: | [EN] (VERSIÓN EN INGLÉS) Droughts are complex natural phenomena difficult to control. The severe impacts they cause to inland water resources and to the associated socio-economic activities justify the continuous monitoring of the drought status in the Júcar River Basin Authority (JRBA). In this territory drought periods of marked intensity have occurred historically. Drought indices are effective planning tools in the monitoring of drought situations. In this work, five standardized indices of drought - some of them widely used worldwide - have been studied. The standardized precipitation index (SPI) for meteorological drought, the Palmer index of drought severity (PDSI) and the normalized difference vegetation index (iNDVI) for soil drought. In addition, a new standardized index related to the status of soil moisture in the soil (iHI) has been developed for soil drought. A comparative analysis that complements the evaluation of the drought status carried out by the JRBA through the operating state index (iSI) is performed with the selected indexes. The Patrical model has been used in the simulation of the hydrological cycle which has used weather data in time real from the Hydrological Information Automatic System of the Júcar River Basin Authority. The input data are completed with the product MYD13Q1 of the EOS-Aqua satellite with MODIS sensor for the characterization of soil drought by standardized vegetation index. The results obtained allowed to advance in the concept of "prolonged drought" established in the Water Framework Directive and required by the European Commission (2007) and prove that neither the meteorological index nor the studied soil indexes provide a real drought perception because they do not take into account water uses and demands in the basin, where the status index takes advantage in the evaluation of operational drought. |
