| Popis: | Factors explaining the temporal variability of peak flows in an experimental catchment of the Central Pyrenees have been studied. This catchment (Arnás, Borau Valley) was cultivated until 50 years ago and is now abandoned; it is characterized by a quick hydrological response against any intensity and volume of precipitation. The total volume of precipitation during each rainfall event hardly explains the intensity of peak flows, which show a high variability. Relationships between precipitation and discharge very much improve if cold and hot season, floods are considered separately. Rainfall recorded during 3 and 7 days before each flood has a relatively important role in winter. During summer and the beginning of autumn the intensity of peak flows are not related to any pluviometric variable, due to evapotranspiration and the separation between rainstorm events. |
