1976. A laboratory study of the effect of slope steepness and curvature on soil erosion. Journal of Agricultural Engineering Research 21(1): 21-31. DOI: 10.1016/0021-8634(76) 90095-0.D.Souza V.P.C,Morgan R.P.C.A laboratory study of the effect of slope steepness and curvature on soil...
The effects of row-sideslope length and steepness on sideslope erosion were studied for four soils at several rain intensities. Row-sideslope length had a major effect on erosion per unit of area where rilling occurred on the sideslopes, but length had little effect on unrilled sideslopes. ...
6. Even today, the depth andsteepnessof Black Canyon make it extremely difficult for humans to access. 即使在今天,黑峡谷的深度和陡度也使得人类难以企及。 youdao 7. The WEPP model underestimated slope factor at great slopesteepnessfor both ESP soils due to hill erosion. ...
Interrill sediment yield, splash detachment, runoff, and sediment size distribution were measured in laboratory erosion pans under simulated total duration of 90 min. Rainfall intensity at 120 mm/hr, 70 mm/hr, and 55 mm/hr were applied sequentially at 9, 25, and 45% slope steepness for ...
Areanalysis of historical and recent data from both natural and simulated rainfall soil erosion plots has resulted in new slope steepness relationships for the Universal Soil Loss Equation. For long slopes on which both interrill and rill erosion occur, the relationships consist of two linear segment...
Method name: Lalpine, Salpine, LSalpineKeywords: Revised Universal Soil Loss Equation, Erosion modeling, Switzerland, Terrain features, Maximal, Flow length AbstractThe slope length and slope steepness factor (LS-factor) is one of five factors of the Universal Soil Loss Equation (USLE) and its ...
For the conditions of the study area, the impact of slope steepness on soil loss was more significant than that of slope length. The erosion estimates are site-specific, but rank of error should be regionally applicable to hillslope and watershedmodels using ArcGIS-based extensions to estimate ...
When the rainfall intensity and duration, and the slope inclination increase, soil loss by erosion from agrogray soils increases higher than from agrochernozems. On the plowland with a slope of 3°, runoff begins 12, 10, and 5 min, on the average, after the beginning of rains at these ...
Restoration of natural vegetation on steep slope in the gullied-hilly area of Loess Plateau is important for soil erosion control. The objective of this study was to find out the relationship between vegetation coverage /aboveground biomass and slope steepness, and the possible relations among ...
However, whether SSIE can be effectively utilized for the quantitative assessment of soil erosion across various types of water-erosion areas and the specific methodology for its application remain unclear. This study focused on the quantitative relationship between SSIE, the slope lengt...
