Water Flow Characteristics Controlled by Slope Morphology under Different Rainfall Capacities and Its Implications for Slope Failure Patterns

The high sensitivity of loess slopes to water has been emphasized in many studies. However, it is still limited terms the understanding slope morphological differentiation on overall and local failure patterns slopes, as well acquisition method hydrological dynamics. In this study, rainfall characteristics surface differences were introduced. Geoelectric environmental factors monitored. On basis, apparent resistivity corrected by seasonal temperature its relationship with soil content was calibrated. migration potential three morphologies evaluated. results are: (i) improved can better reflect flow movement within slope, performs after being temperature; (ii) runoff infiltration are directly affected cumulative value, especially when >70 mm threshold, quickly infiltrates into deep along preferential paths; (iii) interception ability morphology concave > convex linear slope; (iv) continuous rainfall, a prone be damaged saturated mud flow. When threshold 70 mm, easily excited resulting collapse at toe mid-deep landslides.
