Morfología Fluvial.-Funcionamiento de la rambla de Nogalte (Murcia) durante avenidas. Implicaciones para la cartografía de peligrosidad por riesgo de avenidas

Abstract

ABSTRACT Discharge data obtained for the Rambla de Nogalte ephemeral stream by means of hydrologic modelling are low in relation to the discharge that was estimated for the 1973 catastrophic flood event. Watershed characteristics such as an elongated morphology, long stream and moderate slope defining a high concentration time do not favour either large discharge. The reason for it might be the high load attained on the 1973 flood not taken in account for the ordinary hydrologic modelling and the lack of flow evacuation capacity of the aggrading alluvial fan system at the stream mouth.
