Latest version

This plugin simulates landslide dams in river valleys by modifying a DEM. It builds a wedge-shaped dam from the landslide point, direction, volume, face slope and crest slope, grown until the target volume is reached. It then computes the upstream dammed lake with GRASS r.lake (spillway level, volume, area and maximum depth) and outputs the modified DEM, the wedge thickness raster and, optionally, a detailed results table with the landslide point and the lake control points.
