Short summary
This study explores the fluvial morphology evolution in three rivers in Taiwan caused by natural tectonic movements (the 1999 Mw 7.6 Chi-Chi earthquake) and human-made structures (dams). Knickpoints resulting from riverbed uplift shift, leading to gradual evolution from instability to equilibrium. Dams, on the other hand, cause continuous degradation of the bed. When both effects exist on a reach, the impact of the knickpoint gradually fades away, but the effects of the dam on the river persist.
