چکیده
Abstract Soil erosion is a serious hazards occurring in overlaying diluvial fans of shallow underground pipelines. To learn the extent soil such landforms, we propose method susceptibility assessment based on case study Chaka fan, Qinghai Province, China. First, conducted field investigation at 24 sites, to obtain land surface properties. Then, vital information as anti-scouribility, permeability, density, sectional water volume, and pipeline burial depth was collected. The slope grade vegetation index were determined with geographic system (GIS) technology. Further, analytic hierarchy process (AHP) used determine weight various indices potential classification area obtained GIS overlay analysis tool. Lastly, compared results investigation. Their consistency indicates that proposed can be successfully implemented accurately assess erosion. mechanism occlusion cementation have an important influence intensity
