Morfología Fluvial.-Morpholgical change in a stream channel as consequence of the fluvial dynamics (Vallcebre)

Abstract

ABSTRACT This study shows the morpholgical changes observed in a stream channel as consequence of the fluvial dynamics in an experimental research basin (Vallcebre,Eastern Pyrenees). Three cross sections were surveyed along a 100 metres distance near the basin outlet. The cross sections were measured 21 times from 2003 to 2008. Along the study period, higher deposition rates were observed in summer whereas higher erosion rates were observed in April. Considering the whole period, an average resulting deposition of 7 cm has been measured. At the flood scale, correlation analysis, revealed weak correlations between the magnitude of the changes in the stream bed and the main hydrometeorological variables
