Surface runoff and erosion may only be explained by the spatial pattern of ridges, gullies, and rills.
Significantly more injuries occurred in the ramp/bars areas compared to the half-pipe and gully areas, suggesting that SP design may significantly influence injury patterns.
With the much higher resolution of Reconnaissance Orbiter, scientists saw for the first time that the gullies were wider at the center of the pattern.
Furthermore, the spatially continuous survey of the entire form offered the possibility of distinguishing different zones of activity both at the gully rim and within the gully interior, identifying patterns of erosion and deposition which indicate the limited use of headcut retreat rates for the assessment of sediment production on a short-term basis.
Erosion-corrosion is characterized in appearance by grooves, gullies, waves and rounded holes and usually exhibits a directional pattern (Fontana 1986).
The fallout radionuclide 137Cs was used to document rates and patterns of soil redistribution within a small (0.17 km2) gully catchment located near An'sai in Shaanxi Province, representative of the Loess Plateau of China.
The pattern of soil moisture was relatively stationary in two gullies and on the side of a hillslope, but it varied on the valley-head hillslope depending on whether conditions were dry or wet.
Distribution patterns in sediment production caused by water erosion on hills and gully slopes under different land use types were assessed using the fallout 137Cs technique.
It was found that each rainfall scenario produces a unique pattern of erosion (i.e. the location and extent of the gullies is variable).
In particular, the cycles of expansion and contraction in both population and agriculture appear to have affected the susceptibility of the upland landscape to erosion, and the hillslope gullying record in the region, therefore, contributes to understanding of the timing and spatial pattern of human exploitation of the upland landscape.
