A field experiment on coffee cultivation was conducted for 4 years to evaluate the effects of alley cropping and no-tillage on the seed production of coffee and on erosion control in a steep slope area in this region. The cultivation of intercropped vegetables, red peppers, tomatoes, and long...

It is considered that the critical slope and steady slope can be formed for condition of characteristic flow during river closure of main channel. 认为在三峡大江截流特定的水流条件下,可以形成临界坡度和稳定坡度两种坡度。4) stability of erosion control 抗冲稳定性 1. Some problems existing in prac...
An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations.
This paperdescribes the techniques used to reduce the fuel volume on the slopes and to mitigateagainst any erosion or instability due to the removal of vegetation. These two projects are ofinterest because they demonstrate solutions to slope clearance for fuel reduction in high riskfire areas while...
The conclusions reveal that regulation of slope runoff is still an important approach to achieve comprehensive control of soil erosion on engineering and construction areas. 展开 关键词: soil erosion runoff engineering accumulation loess hilly region steep slope ...
Define Steep slope hazard area. means an area on a slope of 40 percent inclination or more within a vertical elevation change of at least 20 feet. For the purpose of this definition, a slope is delineated by establishing its toe and top and is measured b
In this experiment, the sediment mostly came from the middle and the top parts of the slope, while had little erosion in the below part of slope, which was only transported the sediment from the up-slope. 展开 关键词: steep slope sediment transportation critical shear stress loess ...
Shallow slope failures due to erosion are common occurrences along roadways. The use of deep-rooted vegetative covers is a potential solution to stabilize newly constructed slopes or repair shallow landslides. This study compared species that may provide slope stabilization for sites in the Piedmont re...
