Tipo: Abstract
Most watersheds in East and South-East Spain can be classified as semi-arid or arid with large space and time variability in precipitation and river flows. Therefore, water resource systems planning and management must be done with emphasis on drought preparation and mitigation. Administration of water is performed at basin scale by Basin Agencies (Confederaciones Hidrograficas) since early in the 20th century, and water laws enforce the design and implementation of Basin Plans (BP), since 1985, and of Special Drought awareness and mitigation Plans (SDP) at basin and local scales, since 2000. The use of models and Decision Support Systems (DSS) has played an important role in the development of the Jucar Basin Plans for almost two decades, as well as for the development and implementation of the Special Drought awareness and mitigation Plans (SDP). The SDP’s have been formulated according to a proactive approach to drought preparedness and mitigation. They include long term (planning), medium term (alert) and short term (emergency and mitigation) measures that are activated using Standardized Drought Monitoring Indicators (SDMI) based on the use of combinations of data provided by the Automatic Data Acquisition System (ADAS) on precipitation, storage in reservoirs, groundwater levels, and flows in rivers. The SDMI and the curves of thresholds for assessment of the drought situation have been calibrated by intensive use of DSS for drought risk estimation. In order to manage a drought, a participatory Drought Permanent Commission (DPC) is set up, including representatives of all stakeholders in the basin. Besides of the regular use of the SDMI, DSS are also permanently used at the real time management DPC meetings to assess drought risks and vulnerability at medium and short terms. When entering into a drought alert or emergency situation, DSS are a way to assess the risk in the short and medium term, and to evaluate the effectiveness of the measures to modify the risks and to mitigate the impacts of the drought. The experience of using these tools during the 2005-2008 drought is reported. DSS for Jucar Basin has been developed using Aquatool DSS Shell developed at Technical University of Valencia (UPV), facilitating the development and use of hydrological, management, water quality and risk assessment models by the Basin Agency professionals and stakeholders
