METODOLOGÍA PARA LA MODELACIÓN DISTRIBUIDA DE LA ESCORRENTÍA SUPERFICIAL Y LA DELIMITACIÓN DE ZONAS INUNDABLES EN RAMBLAS Y RÍOS-RAMBLA MEDITERRÁNEOS

Methodology for spatially distributed modeling of surface runoff and floodplain’s landscape in mediterranean torrential streams. Many of the Mediterranean basin’s rapid streams are characterised by torrential runoff and are known for causing flash floods. In this paper, a method is proposed to estimate watershed flow continuity and water surface elevations during turbulent stormy events. The methodology is based on a spatially distributed hydrological model that uses a Geographical Information System (GIS) to pre- and post- process hydrological data. The model’s outputs provide rigorous criteria for mapping the floodplain’s landscape.
