Alternatively, you may have identified the opportunity yourself. [6], A wet earthflow occurs where the loss of strength of a section of bank due to saturation increases the weight of the bank and decreases the banks material strength so that the soil flows as a viscous liquid. At the source of almost every ecosystem are trees, serving as home, place of protection and food source for most animal species, and even us humans. However, the water can also erode the shore and wash away any nutrients. Planting trees and hedges can be effective in increasing water infiltration, and reducing and slowing run-off on farmland. Others to try might include white or green ash trees, swamp white oak, and basswood.
