Soil Erosion By Water.
A simple method to help prevent soil erosion by water in the case of a
stream or rain water running down a slope is to grass the area with
grass seed and plant Cornus Alba,the Siberian or Red-Barked Dogwood and
also plants from the willow family Salix. These plants have a root
system that is capable of holding the soil together in a firmer structure
preventing it from being washed away.
