A floating turbidity curtain is designed to contain sediment-laden water and allow enough time for what to happen?

The purpose of a floating turbidity curtain is primarily to contain sediment-laden water in order to allow sediments to settle out of suspension. This type of curtain creates a barrier in the water that helps minimize the movement of sediment particles, which are often stirred up during construction or development activities. By slowing down the water flow within the enclosed area, the turbidity curtain provides the necessary time for the suspended sediments to sink to the bottom, thereby reducing the turbidity and improving water clarity.

The effectiveness of a turbidity curtain is crucial in preventing excess sediment from impacting the surrounding aquatic environment, as high levels of turbidity can harm marine life and disrupt ecosystems. Additionally, allowing sediments to settle out ensures that contaminants bound to those sediments are also captured rather than released into adjacent water bodies.
