Despite heavy rains in the provinces of Valencia and Castellón, rains accumulated up to November in the Community of Valencia are well below the annual average and are insufficient to meet the region’s annual demand for water. The water stored in the Júcar basin in the Valencian Community is 874 hm3, it only represents 26% of the reservoir capacity and is well below the average of the last 10 years, which reflects that the Valencian Community still continues in state of water scarcity and it is necessary to maintain irrigation strategies for periods of drought.
Heavy rains in the provinces of Castellón and Valencia on 27 November in the Valencian Community have accumulated up to 93 liters per square meter in the last 24 hours in the Valencian town of Chera, in Alcudia de Veo in Castellón have been registered 78 liters per square meter, of which 60 mm correspond to the last four hours, according to the Hydrological Information System of the Júcar Hydrographic Confederation.
The rains in the provinces of Valencia and Castellón have been as a consequence of a storm that has settled in front of the Valencian coast around 7 hours, the low barometric pressure, the low temperature and the high relative humidity created conditions favorable to the development of the cold drop, the storm was accompanied by 429 rays that touched land in Valencia of a total of 2,703 rays that did it in all the Valencian Community, according to the data of the State Agency of Meteorology Aemet.
Subsequently already on day 28 accumulated rains reached 152 liters per square meter in some parts of the city. Valencia suffers the greatest waterfall of this decade, flooded avenues, tunnels and closed roads of the metropolitan area. Education suspended classes in schools in Valencia, in the provinces of Castellón and Alicante there was no need to suspend classes. However, the rains accumulated until the month of November are well below the annual average of the province of 475mm for the period 1981-2010.
In the province of Alicante, in the region of Bajo Vinalopó have registered a total of 24 liters per square meter, in the Alto and Medio Vinalopó rainfall is around 20 liters / m2, which greatly favors the start of the campaign of the winter vegetables. In the Marina Alta have been registered little amounts of precipitation in zones of the interior, that do not surpass the 13 liters per square meter, reason why citrus, grapes of wine and cherry are harmed by a water deficit Very severe for months, according to sources of local information.
Also in the province of Alicante a stationary front was created during several days of low pressures, low temperature and high humidity, but the micro climatic conditions of the region were not favorable for the development of intense rains. The accumulated rains for the province of Alicante are insufficient, in the city to date only have been registered around 130 mm, which indicates that Alicante is still in a state of water deficit.
The water stored in the Júcar basin in the Valencian Community is 874 hm3, it only represents 26% of the reservoir capacity and is well below the average of the last 10 years, which reflects that the Valencian Community still continues in state of water scarcity and it is necessary to maintain irrigation strategies for periods of drought.
The water stored in Spain is 28167 hm3 which represents 50.3% of the reservoir capacity, the country’s water reserves are well below the average of the last 10 years according to www.embalses.net
Although some watersheds have experienced improvements in their reserves, there is still a long way to go to recover water reserves to cope with the drought and to guarantee the irrigation needs of each crop in each area of the country.
