In a period of 50 days from the start of the new year hydrological, October 1, 2005 until mid-November, we have moved from a stage of prolonged water shortage with little rainfall to another stage where there is an unequal distribution of the rains, with abundant rainfall in several locations around the region and floods in certain areas, to enter another phase of moderate water deficit, which shows that the problem of the solution of water region is complex and requires multiple actions that allow provide a definitive response to the water needs and drainage for the Communities of Valencia and Murcia to the harmonious development of different sectors of the economy.

The first phase of prolonged water shortage lies at the end of the before hydrological cycle, has been characterized by low rainfall and river flows very low, when compared with a normal year and as result of that, the contribution of water to reservoirs proved insufficient, which resulted that the mean accumulated reserves of the same, in the basins of Segura and Jucar had the lowest values of water reserves in reservoirs of Spain, with a cumulative total of just 739 hectometres cubic. Groundwater largely on exploded, which resulted in an abatement of the high water table and a decrease in the delivery flow of the wells.

In the second phase, which lasted about 15 days is characterized by abundant rainfall in much of the Community, which would decrease in intensity from Castellon to Alicante, usually occurring precipitation peak in the coastal area to the central area of the Community with a average accumulated more high of 110 litters / square meter, with flooding in the province of Castellon as a result of high rainfall, with a cumulative value of 283 litters /square meter in L ‘of Alcudia de Veo. The desired effect was not the best, since much of the rains were retained in the soil, which had a big water shortage, the other side the water achieve to drain superficial or infiltrate deep for a gradual recovery water levels in reservoirs and aquifers.

In the third and current phase only have the water that we have been able to retain at dams, the available water from aquifers and the water reserve that retained soil, which can defer irrigation few weeks or 45 days, depending on the characteristics of the crop. To date 20 November, the accumulated reserve of reservoirs in the basin Segura and Jucar was a volume of only 727 hectometres cubic.

From the foregoing it is noted that: we have a great drought, a major water shortage, the reservoirs are located in middle and upper levels, the distribution of rainfall is not uniform and intensity varies widely and that when precipitation give us the possibility of new contributions to store water, we still do not have enough work to achieve the maximum utilization of rainfall.

You must develop a systematic plan of action in the short and long term that will allow the construction of more dams, regulatory works, transfers, waterworks, and recharging aquifer. , Which are capable of regulating runoff to the maximum, and a plan containing the adequacy of the basin, the protection and cleaning of rivers, the rectification of rivers, and construction of dyke protection, the construction of dams to prevent flooding and improve agriculture drainage systems.

The forest restoring and planting crops covering more of the soil also provide mechanisms for combating floods and avenues. The measures taken to allow proper water policy, which allows for further economic development of the region. To achieve further development is necessary to address hydraulic works much more complex than the current ones, to enable have greater volumes of water available and allow to cope with drought and floods with greater efficiency, as it is necessary to improve the existing infrastructure.
