AB Bedrock rivers offer larger erosive resistance and therefore less incision capability as alluvial streams do.Changes occur very slowly and response to tectonics or eustathism might be not on phase at the differentstream reaches. Along a bedrock gorge, different reaches show changes in hydraulic conditions and ratherdiverse responses on floods. According to the change in slope and transversal sections, erosive and agradationalprocesses are fluctuating in relation to changes in velocity and load transport capacity. Due to the lack ofalluvial floodplain, depth increase abruptly and accordingly stream power acquires a high geomorphiceffectiveness. As it has been observed on the Barranco del Infierno after the occurrence of a low frequencyflood, alluvial deposits have been strongly displaced, resulting in the emptiness of potholes and agradation attransfer reaches. The result of a medium to high magnitude flood is a radical change on fluvial landscape withlarge morphological modifications on bed and banks, bars and even on lateral slopes
