In general, in valleys with large river slopes, rapids dug up the riverbeds and shatter both sides of the mountains, resulting in landslides. Therefore, a debris barrier is constructed to prevent this and to prevent the sediment from flowing down. Constructed here, the gravel is deposited upstream of the dam to stabilize the riverbed with a gentle gradient.

According to the role of the four-sided dam is divided into a low dam to prevent sand and earth flow, a reservoir dam to confine water, and a screen dam to block rocks or logs. Naturally, the reservoir dam can also serve as a low dam.

On the other hand, screen dams are primarily used to prevent driftwood and rock pomegranates caused by landslides and collapse of the banks, and to discharge only soil and runoff slowly, thereby actively preventing downstream damage. Because it is in the form of water, the water and the soil are passed through the dam, but the bulky things such as logs and rocks are not allowed to pass through.
