In general, four-sided dams are civil structures that are installed in the valleys with large river slopes to smash riverbeds and cut off both foothills to cause landslides and to prevent sediments and rocks from flowing downstream along the rapids.

The concrete four-sided dam is most commonly used for the flood damage prevention such as mountain valleys, but this is a four-sided dam for the purpose of water storage and storage.

In addition, steel four-sided dams such as buttress-less and slit four-sided dams cause landslides upstream from mountain valleys to cause driftwoods whose roots are pulled down to be caught in dams, thereby preventing the change of the flow path due to the loss of driftwood or rocks. To prevent damage to cropland.

In addition, the soil flow is a mountain slope that has been subjected to weathering for a long time, and the soil and rock fragments are saturated. Say.

In other words, it can be said to be a kind of landslide that sometimes occurs on the topographical mountain slope.

Not only do these types of soils adversely affect settlements and civil structures (roads, etc.) located in the lower part of the mountain area, but they also take a long time to develop new soil and grow plants when the grounds once occurred. There is.
