  • Stream-subsurface water interaction in loosing and gaining reach of a headwater stream in northern Kyushu

抄録

Stream-subsurface exchange in a gaining and loosing reach of a small forested watershed in northern Kyushu was studied, using hydrometric measurements from wells and piezometers installed in the riparian zone and streambed. There are three stream gauging stations in the watershed of approximately 3ha, identifying loosing upstream reach and gaining downstream reach, during relatively high flow period. Vertical hydraulic gradient measured in the streambed showed steeper downwelling trend in the upstream reach than in the downstream reach. The response of riparian water table to rain events differed between upstream and downstream reaches, suggesting that stream-subsurface exchange dynamics differs between the two reaches.
