Description :
This study examined Takahashi and Sasa's hypothesis of the influence of hyporheic flows on changes in channel form, particularly the formation of head-cut gullies, in an alluvial floodplain. A combination of hyporheic flow (sapping erosion) and channel erosion (bank erosion) appeared to contribute to the formation of the head-cut gullies. Hyporheic flow is an important component in the geomorphic evolution of channels and the floodplain in a gravel-bed river.
