Gully in arid climate.
Collapsing gully erosion developed upon granite residual soil is the most devastating form of soil erosion in southern China. However, despite extensive investigations of the controlling factors of gully erosion, including granite regolith properties (pedon scale), slope geometry and hydraulic conditions (watershed scale), and local climate (regional scale), little is known about the ...
As for climate regimes, they have the strongest correlations in arid or cold regions, and weaker correlations in humid, temperate locations. While remotely sensed soil moisture data are less reliable in dense vegetation, these results confirm that drier, less vegetated climates show a highly linear relationship between soil moisture and rainfall.Climate Variability and Land-Use Change in the Hilly-Gully Region of the Loess Plateau, China Youcai Kang 1,2,3, Jianen Gao 1,2,3,4,*, Hui Shao 5 and Yuanyuan Zhang 1,2,3 ...
