Research Abstract

Sediment discharges by the groundwater discharge at mountainous hillslope and its effect on the shallow landslide, is still incomplete. A dense observation study was conducted to understand the groundwater and bedrock groundwater movements and sediment discharge. We observed relatively homogeneous groundwater movement and the exfiltration of bedrock groundwater, forming perennial groundwater thatwas very specific and local.
