Nrcs slope stability
WebSlope Stability - General. Slopes are typically categorized in two types: natural and artificially-made slopes. Natural slopes are formed due to physical processes that include plate tectonics and weathering/erosion of rock masses that result in material deposition. WebExercise 13.4 Determining Stream Gradients. Gradient is the key factor controlling stream velocity, and of course, velocity controls sediment erosion and deposition. This map shows the elevations of Priest Creek in the Kelowna area. The length of the creek between 1,600 m and 1,300 m elevation is 2.4 km, so the gradient is 300/2.4 = 125 m/km. 1.

WebOasys Slope performs two-dimensional slope stability analysis using the method of slices (Limit Equilibrium) and presents the results in a clear graphical format. Users can apply partial factors, including EC7, easily. Slope includes the option of finite element steady state seepage analysis or defined pore pressure distribution.
WebThe type of slope stabilization needed depends on the steepness of the slope. For slopes under 50% (approximately 30 degrees), establishing vegetation may be all that is needed to stabilize the slope and control erosion. On slopes greater than 50%, engineered structures may be necessary.
