Soil Erosion and Controls in the Slope-Gully System of the Loess Plateau of China: A Review

Frontiers in Environmental Science, 2021
The Loess Plateau has long been suffering from serious soil erosion of which erosion from the slope-gully system is now dominant. The slope-gully system is characterized with distinctive erosion distribution zones consisting of inner and inter gully ...

A New Method to Predict Gully Head Erosion in the Loess Plateau of China Based on SBAS-InSAR

Remote Sensing, 2021
Gully head erosion causes serious land degradation in semiarid regions. The existing studies on gully head erosion are mainly based on measuring the gully volume in small-scale catchments, which is a labor-intensive and time-consuming approach. Therefore,
