Medidas de mitigação e controlo de ravinamento: um estudo de caso das ravinas de Seirós (Norte de Portugal)

Abstract

Ravine mitigation and control measures: A case study of the ravines of Seirós (Northern Portugal). The erosion process triggered by gullies is known to contribute significantly to soil loss and degradation, which can often limit land use and occupation options. The variety of physical factors associated with the installation and evolution of gullies makes interpretation difficult and requires a well-founded analysis based on local observation. In this work, the installation of a set of gullies in an agricultural area near Seirós, Ribeira de Pena (Northern Portugal) is analysed. Besides the characterization, it is also investigated the adequacy of the protection strategy implemented by the owner and presented mitigation measures towards soil erosion control and rehabilitation of the affected area.
