Sometimes you can resolve erosion problems by installing gutters and downspouts and directing runoff to another stable area. If your erosion problems are complex, you may need to consult a professional engineer. Installing gutters at the roof edge, diverting rain water away from the slope to a stable area and transporting water down the slope in a reinforced channel or into a recharge area will all help prevent erosion due to rainfall. You may need to consult a professional engineer to solve these problems. Slope angle can vary with different soils.
Soils form an angled slope that varies with the soil and groundwater conditions.
Banks will erode until they reach their natural angle of repose. Planting vegetation, and installing riprap protection and gabions will help with this problem. Thick, healthy vegetation contributes greatly to slope stability by holding the soil together with it's root structure. Carefully examine the quality of the vegetation on the slope. Planting the right combination of riprap protection, gabions and vegetation.
