Giant landslides topography and erosion

WebOeschinensee is situated in the Bernese Alps, [6] within a 5 kilometres (3.1 mi) long side valley of the Kandertal, and lies at about 1,578 metres (5,177 ft) elevation. It receives inflow from glaciers and springs, while its waters eventually seep through landslide debris although in the past (before a small dam was built) the lake periodically ... WebThe southeastern Tibetan Plateau has been deeply dissected by major rivers and their tributaries into high-relief topography with deep gorges. In this region, most hillslope gradients in the high-relief areas approach a threshold value, and landslides are the dominant surface erosion process. For this work, we analyzed the hillslope erosion …
