Factors affecting soil loss at plot scale and sediment yield at catchment scale in a tropical volcanic agroforestery landscape

erosion, landslides and the concentrated flow erosion on footpaths and roads can contribute to more targeted efforts and relevant incentives to reduce (or live with) sediment load of the rivers.

Spatial interaction between collapsed pipes and landslides in hilly regions with loess-derived soils

flow, resulting in pipe development. No evidence was found that pipe development enhanced LS, probably because the subsurface drainage discharge generated upslope of the LS is too low. Even when pipes become blocked, it is more likely that new pipes

Spatial patterns, causes and consequences of landslides in the Gilgel Gibe catchment, SW Ethiopia

further away from the rivers. Deforestation caused higher runoff and hence more landslides along the rivers. Heavy rainfall is the main triggering factor.

Predicting runoff and sediment connectivity and soil erosion by water for different land use scenarios in the Spanish Pre-Pyrenees

that : connectivity is high in irrigation channels and agricultural terraces; vegetation factor is as important as the linear landscape elements; more erosion is predicted at the early stage of future land abandonment.
