| Sumario: | [EN] The Water Framework Directive establishes a framework for Community action in the field of water policy whose main objective is to achieve good status of all water bodies. Its transposition into Spanish law has tried to implement in developing basin hydrological plans by applying Water Planning Instruction. A major challenge facing Water Plans is the balance sheet adjustment of resources and demands, taking into account the rights and existing priorities, compliance with environmental objectives. The calculation of balances at first glance seems simple, but in practice it is complicated due to various reasons such as insufficient and poor quality of the data, or the different options in the selection of data to be considered. Another serious problem is the loss of information due to the variable aggregation that generates hidden problems on the watershed management. The methodologies used in Spain are focused on the evaluation of available resources by using optimization techniques, likening it to the maximum demand that can be supplied according to warranty criteria. On the other hand, European methodologies make the balancing approach by gathering information emulating the hydrologic cycle in a territory. Taking as a study case the Jucar river basin, different estimations of the available resources have been obtained according to the origin of the series contributions, the period simulation length and the warranty criteria used to consider all demands satisfied. The results obtained present a lot of diversity, due to the system complexity. The European Union is looking for finding an indicator system to be equally valid for all the country members’ basins. This approach may not be valid in countries like Spain, where the long tradition in planning and management of water resources can be more demanding than EU itself. It has to be taken into account that the EU is made from countries with different physical characteristics, different hydrology and economies based on various productive sectors and with differences on demands and infrastructures. In this situation, a first step may be to conduct a preliminary classification of the regions that comprise the EU in order to apply different methodologies that are appropriate to the physical and socioeconomic characteristics of each of the member countries. |
