Las crecidas en ramblas valencianas mediterráneas

Abstract

En este artículo se caracterizan los cursos fluviales efímeros propios de la cuenca mediterránea. Las fuertes avenidas que registran se deben a las características físicas de las cuencas (fuertes pendientes, escasa vegetación, suelos delgados) y a las lluvias intensas, voluminosas y con una distribución espacial irregular que caen en muy pocas horas. Con estos condicionantes la conversión lluvia-caudal se realiza de forma brusca, dando lugar a avenidas súbitas (flash-flood), de hidrogramas apuntados, de escasa duración y tiempo de retraso mínimo. Los volúmenes escurridos, sin embargo, sólo son una proporción mínima de la lluvia caída sobre las cuencas, que por sus características propician la infiltración de grandes volúmenes de agua. Dans cet article on caractérise le fonctionnement hydrologique des ravines méditerranés. Ces environnements subissent énormes crues, dues d'un coté aux caractéristiques physiques des bassins versants (fortes pentes, sols maigres et une très faible couverture végétale), et, d'autre coté, aux intenses pluies qui précipitent grandes volumes d'eau en quelques heures, même minutes. Sous ces conditions, les processus de conversion pluie-débit provoquent crues du tj^e flash-flood, avec hydrographes très pointus et courts temps de réponse. En utilisant les donnés journaliers du basin de la Rambla de la Viuda et des donnés pris tous les cinq minutes dans les bassins de Carraixet et Poyo, on a analysé le comportement hydrologique de ses courses d'écoulement éphémère, pendant la formation de crues.
