Recent studies carried out in twelve rivers have allowed to re-examine existing conceptual models of channel evolution for Italian rivers.

Abstract

Recent studies carried out in twelve rivers have allowed to re-examine existing conceptual models of channel evolution for Italian rivers. The presence of three main phases of channel evolution is confirmed for some river reaches, while in other re- aches the third phase (generally occurring over the last 15-20 years) is still unclear since river channels could be already in a quasi-equilibrium condition. Besides, while the first phases of adjustment were caused mainly by alterations of sediment regime, the very recent channel evolution appears to be strongly controlled also by flood magnitude and frequency.
