This document summarizes the landslides that have occurred along the banks of the Dagangshan reservoir in China. It finds that numerous landslides have developed since impoundment, mainly consisting of shallow slides in accumulative layers or weakened rock masses impacted by water level changes and weathering. Seven unstable slopes were identified that show signs of large deformation, local collapses, and tension cracks induced by water level fluctuations. Overall, the landslides are associated with reservoir water levels and precipitation, and are spatially distributed along known faults and in weak, water-sensitive deposits and rocks. Two failure models are proposed to explain the deformation processes observed on representative slopes. While landslides are less extensive compared to other Chinese reservoirs, smaller water level
