Una semana después de que commenzara la DANA del siglo, de poco sirve —sobre todo, a los que han perdido todo— hacerse preguntas como “What would have happened if they had taken appropriate action?“.
One of the most questioned was the notification received on the phones of the citizens last Tuesday, despite the warnings issued by Aemet the previous day. Aunque también ha habido quienes han pointed to decisions made decades ago.
Only 20 years Gobierno announced the construction of a dam in Cheste evitar las riadas for the 16 municipalities of valencia; Among those who are now most affected by DANA (Aldaia, Paiporta or Chiva). It is estimated that there are 200,000 settlements that are affected by natural disasters.
In 2005, a deviation from the National Hydrological Plan paralyzed it. Six years later, Then the Nazirio de Medio Ambiente rechazó to the pressque aparecía como first alternative to be more favorable in environmental impact studies, giving priority to the construction of green roads, “through the restoration of the biological environment, habitats and the reduction of the occupation surface with infrastructure and socio-economic environment”.
Una measure “effective”
Sin embargo, the high cost of this type of construction (about 300 million euros) ocasionó, con la llegada de la economic crisis, que no se pusiera en marcha un proyecto que preveía aumentar el caudal del barranco del Poyo hasta los 1,500 m3/s. Actual production capacity is 800 m3/s. “Esto no quiere decir que los daños se hubieran reducido a la mitad, pero sí que poterza haber sido muy inferiores”, assures EL ESPAÑOL. Federico BonetFormer Dean of the College of Civil Engineers of Valencia.
“This will help you avoid any damage“, he added Xavier BaztanMember of the General Council of the College of Roads, Canals and Harbors Engineers. Both agree in pointing out that a dam such as the Cheste can hold some of the volume of the riad. The final conscience is the high productivity that reaches 2,000 m3/s.
In El Río Magro, one of the areas affected by DANA, an avenue lamination dam was planned at the turn of the century. Las también conocida como “presas de agujero” laminar la avenida de manera que funcción var. los caudales que salen de la presa sean muy inferiores at the entrance. Y port tanto, se evitan los daños aguas abajo de la presa.
The construction of a dam on the Canyoles River in the municipality of Montesa (Valencia) is also expected. However, Bonet laments, “en los últimos 20 años no se ha realizado ninguna obra hydricica”. Suspecha que se debe a que son “It is very expensive economically and socially“.
Los ingenieros ponen el ejemplo del desvío was carried out in El Turia in 1957 to demonstrate this. los encauzamientos se han demonstrated “effective”.Avoid flooding in the city of Valencia itself”.
El director del Instituto de Investigación en Ingeniería del Agua y Medio Ambiente de la Universitat Politécnica de Valencia (IIAMA-UPV), Manuel Pulidocree que “la presa hubiera laminatedo bastante”, teniendo en cuenta los caudales que se han superado. Therefore plantea una restauración hydrológica forestalcon pequeños diques de la cuenca alta del barranco, que es donde se generan los caudales.
John “una parte controvertida”
The floods released by DANA in recent days made news in places like Spain 2.7 million people live in non-flooding zones. Madrid David Uribelarrea Universidad Complutense de la geologo de la como commenta “controvertida una parte” presas tiene construcción.
However, partially reduce the flooding. But on the other hand, they also create a false sense of security. Therefore, understand that it is more convenient to plan the area well before building infrastructures that have a large impact on the environment: “Now we cannot fill the valleys of the Spanish Levant, because It would be an environmental disaster“.
Delegation of the Colegio de Geólogos in Comunidad Valenciana, Joaquin Martinezincide en llevar cabo una buena regulation de las zonas inundables: “Entiendo que a otras professionals no le gusta lo que nosotros” [los geólogos] let's say But if you build a barranco with cement, there is no leakage.”
Aunque, como apointa el exdecano del Colegio de Ingenieros de Caminos de Valencia, en las zonas afectadas allredero del barranco del Poyo “it is necessary to construct practically“, por lo que no cree que tenga sentido or forbidden constructir en estas zonas: “Lo que pienso que hay que hacer ahora es protegerlo de alguna forma”.
“There are no Buscar culprits,” continues Bonet, “because after the crisis came another government of Mariano Rajoy and Pedro Sánchez. This is the problem of the whole societyde estar más concienciados”.
