Soil Detachment Rate of a Rainfall-Induced Landslide Soil

In recent decades, the number of rainfall-induced landslides has increased significantly in many parts Malaysia, especially urbanized and hilly areas. The disturbance morphology as a result human activities potential for erosion on man-made slopes, during extreme rainfall rain events. Most areas Malaysia are covered by thick layer soil, which is known to have significant impact soil erosion. However, little about how could be driving force behind landslide initiation, stabilized slopes. Therefore, this study focuses detachment rate triggered at different intensities. A sandbox model used represent real slope conditions. relationship between capacity, properties (water content, slope, clay layers compaction), hydraulic parameters (flow shear stress stream power) intensities (low, medium high) was investigated. results showed that intensity directly proportional soil. Water content show higher lower critical flow than other properties. It can concluded high saturation steep increase risk because cohesion friction reduced, leading weakening structure surface. feed into existing analysis stability formulate onset rainfall, eroded soils.
