Abstract

The AA. developed statistical models of colluvium and shallow-groundwater distributions to aid landslide hazard assessments. The models were developed using a geographic information system, digital geologic maps, digital topography, subsurface exploration results, the groundwater flow modeling VS2DI and regression analyses. Input to the colluvium model includes slope, distance to a hillslope-crest escarpment, and escarpment slope and height. The AA. developed different statistical relations for thickness of colluvium on 4 landforms. The results suggest that Seattle landslides occur in native deposits and colluvium, ultimately in response to surface-water erosion of hillslope toes
