In flowing water, turbidity curtains should be placed parallel to the direction of flow, not which other direction?

Turbidity curtains are employed in water management practices to contain suspended solids and mitigate the impact of sedimentation during construction activities. When utilizing turbidity curtains, it is essential to position them parallel to the direction of flowing water to effectively capture and contain particles without disrupting the natural flow and causing turbulence that could spread the contaminants.

Positioning turbidity curtains in a perpendicular direction to the flow would create challenges. This orientation can lead to increased turbulence, allowing suspended particles to bypass the curtain and continue downstream, thereby undermining its purpose. Additionally, a perpendicular placement may not adequately contain the sediment-laden water, resulting in potential environmental impacts.

Understanding the proper installation orientation of turbidity curtains is vital for effective sediment control and compliance with environmental protection standards in stormwater management. This reflects the critical practices necessary for maintaining water quality in construction sites or areas with potential erosion concerns.
