Abstract

Before equilibrium can be reached again, a river bed must incise deeply for considerable distance upstream. Thereupon the river will start to make a new set of meanders not unlike the old meander pattern. The one-dimensional open-channel flow equation, when applied to river erosion (triggered by meander cutting), shows that the half life of such man-made disturbances ranges from hundreds to a thousand years. Consequently, man-made interference with natural rivers represents a costly capital operation, which requires a long term (50-100 years) commitment for up-keep, improvement and replacement, if not in the short run, then in the long run (next 500 years).
