Centennial Channel Response to Climate Change in an Engineered River

Human intervention makes river channels adjust their slope and bed surface grain size as they transition to a new equilibrium state in response engineering measures. Climate change alters the controls through hydrograph changes sea level rise. We assess how channel climate compares human over this century (2000–2100), focusing on 300-km reach of Rhine River. set up schematized numerical model representative current (1990–2020), non-graded river, subject it scenarios for hydrograph, sediment flux, conclude that lower River will continue past channelization measures 2100 incision. This slows down approaches its state. Channel is dominated by changes, which increasingly enhance incision, rather than
