1) Regularly clean the culvert
2) Install a debris screen
3) Increase the size of the culvert
4) None of the above

Answer 1

To stop debris from reducing a culvert's capacity, you can regularly clean the culvert, install a debris screen, or increase the size of the culvert.

Step-by-step explanation:

To stop debris from reducing a culvert's capacity, there are several measures that can be taken:

1. Regularly clean the culvert: Clearing the culvert of any accumulated debris will help maintain its capacity and prevent blockages. This can be done through regular inspections and maintenance.
2. Install a debris screen: Placing a screen or grate at the entrance of the culvert can help trap larger debris and prevent it from entering the culvert, thereby reducing the risk of capacity reduction.
3. Increase the size of the culvert: In some cases, if the debris accumulation is significant or recurrent, increasing the size of the culvert may be necessary. This allows for a larger flow area and reduces the likelihood of capacity reduction.

By implementing these strategies, the culvert's capacity can be maintained, ensuring proper flow of water and reducing the risk of flooding.
