How was hillslope formed?
Hillslopes constitute the flanks of valleys and the margins of eroding uplands. They are the major zones where rock and soil are loosened by weathering processes and then transported down gradient, often to a river channel.
Does China have soil erosion?
In China, soil erosion is also a major environmental and ecological problem. Soil and water conservation is the key to soil erosion control and development of an ecologically stable environment and society.
What caused soil erosion in China?
While experts cited farming and forestry as the main causes, contributing to over a third of the area affected, the research team said erosion was damaging industrial areas and cities as well as remote rural land.
What are the components of hillslope?
Hillslope
- Debris Flow.
- Gully.
- Overland Flow.
- Rainfall.
- Soil Erosion.
- Infiltration.
- Bedrock.
- Runoff.
What is a hillslope system?
Hillslopes are an integral part of the drainage basin system, delivering water and sediment to streams. They range from flat to steep. Commonly, hillslopes form catenas – sequences of linked slope units running from drainage divide to valley floor.
What is China’s deforestation?

What causes hillslope failure?
Many factors can act as triggers for hillslope failure. One of the most common is prolonged or heavy rainfall. Rainfall can lead to mass movement through three different mechanisms. Often these mechanisms do not act alone.
What is hillslope diffusion?
Hillslope diffusion introduces a point of inflection in the semivariogram. The location of this point of inflection can probably be used for quantifying the ratio of diffusivity and fluvial erodibility and thus the influence of hillslope diffusion on relief for real topographies.
What causes deforestation in China?
Therefore, the causes of deforestation are identified as demand for timber, population-driven land reclamation up to 1980, and urbanisation in the last two decades.
What impacts does deforestation have on China?
In some areas in China, desertification has been a major consequence of this deforestation, which occurs when native tree species are removed, altering the water retention capacity and porosity (how much air the soil retains) of the soil, allowing wind to sweep it away seen in Figure 1.
