What is the main benefit of engineered erosion control structures, like diversions?

The main benefit of engineered erosion control structures, such as diversions, is to redirect water flow and reduce erosion. These structures are designed to manage surface water runoff by guiding it away from vulnerable areas, thereby minimizing the risk of soil loss due to erosion. By controlling where the water flows, these systems can help maintain soil integrity, protect vegetation, and promote overall land health.

Effective diversions can also reduce sedimentation in waterways, which is important for protecting aquatic ecosystems and water quality. In contrast, practices that encourage soil erosion, eliminate vegetation, or facilitate more intensive tilling do not support the goals of erosion control and can lead to adverse environmental impacts.
