Fire influences on hydrological behavior of two catchment in the Aragoneses Pre-Pyrenees (Spain)

M. T. Echeverría Arnedo, P. Ibarra Benlloch, M. Sebastián López, F. Pérez Cabello


The hydrological behaviour of two basins affected by a forest fire. The different percentage of burnt surface in both areas is translated in a different hydrological behaviour, analysed through the discharge hydrograms and a comparative statistical analysis. In the burnt catchment area, the hydrological response to the precipitation is bigger and faster than in the other basin, in relation to a greater superficial runoff and a smaller infiltration rate (mean runoff coefficients: 10% compared to the 4.8% obtained at the non-burnt catchment).
