Which outcome arises when excessive development restricts floodplains near levees?

💡 Explanation

Increased floodplain restriction due to development causes increased river flow velocity and hydraulic pressure, resulting in increased erosion. This occurs because the decreased channel roughness height increases sheer stress; therefore, erosion increases rather than nutrient balance which depends on other factors.
