As an important component of stream-subsurface exchange processes,lateral hyporheic exchange plays a crucial role in maintaining health of river and riparian ecosystems.In order to reveal the discipline of lateral hyporheic exchange induced by bank morphology,10 runs of circulation flume experiments with idealized sinusoidal curved bank and 4 runs of comparison experiments with straight bank were conducted in varying flow conditions.The experimental results showed that the lateral hyporheic exchange also co...
