19. In the space below, explain one method you learned in the videos above that the people living on the Le Sueur River could implement to lessen the impact of erosion on the riverbank.

Answer 1

One method the people living on the Le Sueur River could implement to lessen the impact of erosion on the riverbank is planting native trees and shrubs along the riverbank. Trees and shrubs have deep root systems that can help stabilize the soil and prevent it from eroding. By planting native vegetation along the riverbank, the roots of these plants can help hold the soil in place and reduce the amount of sediment and nutrients entering the river. This method can also create habitat for wildlife and improve water quality in the river. Additionally, creating vegetative buffer zones along the riverbank can help absorb stormwater runoff and reduce the risk of erosion during heavy rainfall events.
