To what purpose should check dams be installed during construction?

To increase water flow
To create aesthetic features
To temporarily retain water and sediment
To enhance vehicle access

The correct answer is: To temporarily retain water and sediment

Check dams are specifically designed to temporarily retain water and sediment during construction activities. They serve as a crucial erosion and sediment control practice by creating small barriers across the flow path. By doing this, they slow down the velocity of stormwater runoff, allowing sediment to settle out before it can be carried away into downstream water bodies. This is essential for preventing sediment pollution, which can be harmful to aquatic ecosystems and water quality. This retention of water and sediment helps to protect the surrounding environment by minimizing the impact that construction activities can have on nearby streams, rivers, and lakes. The primary goal of using check dams is to control erosion, improve water quality, and ensure compliance with environmental regulations. Hence, their installation is a best management practice that addresses sediment control effectively during construction phases.
