Abstract

This work presents an analysis of the response to rainfall of ephemeral streams in a karst semi-arid regions of southeast of Italy by an innovative approach. The analysis is based on a 2D simulation model of the behavior of a network of ephemeral streams. The used approach integrates the hydrological and hydraulic models in order to account first for the dynamic of catchment response to rainfall and activation of the streams, and then for the hydraulic behavior of the streams. Results show the slow response of ephemeral streams to the rainfall, whereas more extreme rainfall events generate quick and high discharge responses of the ephemeral streams. In addition, modeling results emphasize the non-linearity of runoff generation, in particular for some flow paths, which are biased by the local morphology as well as by the intensity of the rainfall event
