What purpose do graded slopes serve in erosion control practices?

Graded slopes play a critical role in erosion control practices primarily by helping to redirect water flow. Proper grading alters the slope's angle and shape, influencing how water moves across a site. When water flows too quickly or in an uncontrolled manner, it can cause significant erosion by dislodging soil particles and carrying them away. By designing graded slopes to direct water in desired paths, it's possible to manage runoff effectively, minimize erosion risks, and enhance sediment control. This technique is a fundamental aspect of effective erosion control strategies as it contributes to maintaining soil integrity and preserving the environment around construction sites or land disturbed by development activities.
