Predicting soil erosion
Conventional soil erosion models are generally based on the Universal Soil Loss Equation (USLE), or a revised (RUSLE) or modified (Williams and Berndt (1977)) version of the USLE. Betrie et al (2011) used the Soil and Water Assessment Tool (SWAT), which uses MUSLE to compute soil erosion, to model sediment transport in ...

The Virunga landscape has one of the greatest diversities of habitats globally within about 790 thousand hectares. Thousands of hippopotamuses and elephants live in the park's rivers and its mountains are a critical area for the survival of the mountain and lowland gorillas. However, these habitats have undergone dramatic changes in land cover and ...
