Stormwater Erosion And Sedimentation Control Practice Exam

Anchor lines should be attached to the buoys of the structure. This is because buoy systems are designed to keep floating barriers or curtains in place, allowing them to function effectively in managing stormwater runoff and sediment control. By securing the anchor lines to the buoys, the barriers remain stable and are less likely to be displaced by currents or wind, ensuring that they maintain their intended position and effectiveness in trapping sediment and controlling water flow. Other options, such as the bottom of the curtain, float of the curtain, or the water surface, do not provide the necessary stability or configuration that buoys offer for anchoring. Attaching lines to the curtain itself could lead to distortion or limit its movement with water flow, while securing to the water surface does not provide a reliable method of holding the curtain in position against environmental forces.
