ABSTRACT

MEFIDIS: A Physically Based, Spatially Distributed Runoff and Erosion Model for Extreme Rainfall Events

Joao Pedro Nunes, G. Nuno Vieira, and J. Seixas

This chapter presents the MEFIDIS runoff and soil erosion model (MEFIDIS: Modelo de Erosão FÍsico e DIStribuído – Physical Distributed Erosion Model). It was developed to assess the consequences of extreme rainfall events for flooding and soil loss in medium-sized watersheds, and to evaluate the consequences of climate and land use changes to catchment response. It provides distributed results in space and time to allow the analysis of withincatchment properties and time-variable hydrographs.
