Water and Irrigation Vol .: 7, No. 1: 34-35, December, 2016, Spain.

During the autumn period from October to December 2016 as a result of bad weather and cold drop there have been major floods in different regions of the Spanish east that include the communities of the Mediterranean area: Catalonia, Comunidad Valenciana, Baleares, Community of Murcia and the provinces of Almeria and Malaga in the Community of Andalusia. The intense rains caused flooding of streets, roadblocks, car trawling and all that the water found in its path, as well as floods in agricultural areas, causing human losses and large economic losses, which shows that the adopted measures against the floods are still insufficient and it is necessary to improve urban and agricultural drainage much more throughout the Spanish Levante.

 

The torrential rains that affected the coastal strip of the Costa Dorada in Catalonia on October 12, caused great floods, the death of a man and economic losses, the strong flow dragged the cars and everything that the water found in its path, Many people had to take refuge in restaurants and nautical clubs in the area. Rainfall of 220 millimeters was recorded in a period of 4 hours that caused the flood of streets and the passage of underground pedestrians that allows the crossing of the N-2 route and the railway line. In these localities the trains were forced to circulate slowly, which caused delays in the circulation.

Heavy rains of 18 mm in 5 minutes with an intensity of 3.6 mm / min. And wind gusts on November 22 in the province of Almeria, mainly in El Ejido and the strip coast, have caused great losses in rural roads, hail between greenhouses and the rescue of people in cars trapped in flooded areas as well in flooded agricultural areas,. The Hidrosur Network of the Community of Andalusia in the Almanzora Valley recorded an average of 82 liters / m2 in Cantoria and 76 liters / m2 in Velefique. Subsequently in the region on December 18, accumulated rainfall of 100 l / m2 is reported in 12 hours.

The intense rains on November 27, in the provinces of Valencia and Castellón as a result of a storm that settled in front of the coastal coast of Valencia, lasted 7 hours and 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 the whole Valencian Community, accumulated up to 93 l / m2 in 24 hours in the Valencian locality of Chera and 78 liters per square meter, in Alcudia de Veo in Castellón according to the hydrological information system of the Júcar Hydrographic Confederation and the data of the State Meteorological Agency Aemet. Later on day 28 accumulated rains reached 152 l / m2 in some parts of the city. Valencia suffers the greatest waterfall of this decade, flooded avenues, tunnels and closed roads of the metropolitan area.

The December 4 storm in the province of Málaga in the Community of Andalusia, left in Estepona precipitation of 204 liters / m2 in 12 hours, of which 81 fell in an hour and record a new record, higher than those of the floods of 1989. Saturday’s rainfall claimed two lives, flooded streets and flooded homes located in low areas, caused numerous damages, many places on the Costa del Sol in the province. The municipalities most affected by the floods were Estepona, Marbella and Cártama.

Torrential rains and strong winds of December 17 in the Autonomous Community of Murcia as a result of bad weather caused cuts of 10 roads, floods of streets, overflow of sewers, landslides, flooded fields of crops, a victim and rescue of people in their cars. Cartagena was the region where it rained the most, where the rain gauges of the Aemet recorded 84 liters per square meter in 21 hours. Murcia was one of the most punished cities.

Cold drop again affects the Valencian Community more intensely during the 16 to 19 December, but this time there are 25 zones with precipitations of more than 200 mm, all mainly to the south of the province of Valencia and north of the province from Alicante. Record accumulated rains for the analyzed period of 404 liters / m2 in Beniarrés and of 307 in the Wall of Alcoy both of the province of Alicante, in the province of Valencia recorded accumulated maximum of 329 and 271 liters / m2 for Pinet and Ontinyent respectively , In the province of Castellón recored accumulated rain was 206mm and was recorded in Alfondeguilla, according to the networks of AEMET and the Júcar Hydrographic Confederation.

Rainfall accumulated during December in the Valencian Community has made it the wettest month since 1989, which has caused flooded streets, flooded rivers, cut roads, two human losses, flooded crop fields and large economic losses. The year started with dry features and ended up very wet.

The storm of heavy rains that has hit the Balearic Islands has caused: flooded streets, cut roads, landslides and incommunicado municipalities, in Mallorca has registered on December 20 an average rainfall of 110 / m2, in Ibiza 100 l / M2, in Formentera 90 l / m2 and in Menorca 30 l / m2 according to the State Agency of Meteorology in Baleares. The municipality where it has rained most has been Llucmajor and have registered133 l / m2.

The fight against flooding must be intensified, it is necessary to make decisions in time to counteract the damages caused by excessive rains, the investments to be carried out to ensure these measures are less than the human and material losses caused by them, It is not necessary to wait for large losses as a result of excessive water to develop a more effective strategy. Urban drainage systems should be designed according to the effects of cold drop and the new challenges of climate change that will enable a more rapid evacuation of urban runoff, as well as agricultural drainage systems that guarantee greater safety to the population, tourists, material goods, agriculture and tend to minimize human and economic losses.
