This presentation reports about a very large flood (20-30 years return time interval) that markedly affected teh step-pool geomorphology of the streambed of a steep mpuntain stream. The geomorphic parameters and data of the step-pool sequences before the flood are compared with those after the flood. Importnat changes were observed. They include teh widening of teh step-stpe wave length, the removal of old steps and the generaion of the of new ones. The stream bed re-organisation induced by such a big flood is anlysed.

Abstract
This presentation reports about a very large flood (20-30 years return time interval) that markedly affected teh step-pool geomorphology of the streambed of a steep mpuntain stream. The geomorphic parameters and data of the step-pool sequences before the flood are compared with those after the flood. Importnat changes were observed. They include teh widening of teh step-stpe wave length, the removal of old steps and the generaion of the of new ones. The stream bed re-organisation induced by such a big flood is anlysed.File in questo prodotto:
