Quantitative data about present fluvial geomorphic processes in Riera de Fuirosos.

Abstract

In this work, are exposed the results of four years measurements of fluvial geomorphic activity in a little catchment. This activity is the most effective process in the evolution of the basin. Nevertheless, its action varies notably as much in the space as in the time; in the jirst case, this is due to the geomorphic properties of the studied section; in the second, it is due, to the characteristics ofmeteorological events. Here the erosion rates of stream bank are higher than in the temparate countries, and lower than in the semi-arid zone, but they are within the expected rates. The observed ejfective processes have been the standard for this climatic area
