The first stage is the circulation phase (A) where the soil is deposited or eroded in the gravel at the bottom of the river.

In the circulation step (A), when the amount of the soil supplied from the outside increases in the water flowing in the lower part, the soil is gradually deposited in the permeable gravel. However, when the flow of water is accelerated due to heavy rain or flood, And the elevation of the road is kept constant.

The second stage is a plant invasion phase (B) in which vegetation penetrates into the undergrowth and the erosion of the soil is reduced.

The plant invasion phase (B) reduces the flow of water by the aquatic plants, while the roots of the aquatic plants bind the deposited soil as the aquatic plants are rooted in the gravels deposited in the permeable gravel to reduce the loss of the gravel .

Step 3 is a soil deposition step (C) in which the soil is deposited on the permeable gravel while the erosive action of the soil is reduced by the aquatic plant.

The sedimentation step (C) is characterized in that sedimentation is more active than the erosion of the earths by the aquatic plants, and sedimentation of the earths occurs more than the water surface of the lower part.

The fourth stage is the plant settlement stage (D) where the waterside plant is settled on the sediments over the water surface of the lower reaches.

In the stage of plant deposition (D), the gravels deposited above the water surface of the lower waterway are flooded or exposed according to the water content of the waterway, and as a result, .

Step 5 is a soil stabilization step (E) in which the soil deposited by the waterside plant is stabilized.

In the soil stabilization step (E), the soil to which the waterside vegetation grows is characterized in that the sedimentation is further accelerated, and the soil is stabilized to such an extent that even if the surface of the water surface becomes maximum due to heavy rain or flood, it is not flooded.

Phase 6 is the stage of plant competition (F) where plant species competition occurs on stable soil.

At the stage of plant competition (F), the land plants thrive on the watershed plants to become more prosperous, eventually forming a bush.

In addition, the evaluating unit 300 determines that the elevation of the selected area using the terrain determining unit 100 is lower than the reference elevation stored in advance in the underground sedimentation evaluation table, and uses the plant determining unit 200 to determine If a native waterside plant is identified, it is determined that the selected zone is in the plant deposition stage (D).

In the present invention, the reference elevation is based on the water surface height of the lower waterway. In the present invention, a value obtained by adding 100 mm to the annual average water surface height of the lower waterway is used as a reference, but it is extremely easy for those skilled in the art to understand that the reference elevation can be changed have.

The waterside plant is a plant that grows well even when it is exposed to the ground or submerged due to heavy rain or flood. Typically, it has a reed, a rootstock grass, and a shovel.

Also, the evaluating unit 300 determines that the elevation of the selected area using the terrain determining unit 100 is higher than the reference elevation stored in advance in the lower elevation assessment table, and uses the plant determining unit 200 to determine When a wild vegetation is identified, the selected area is judged to be in the soil stabilization step (E).

The evaluating unit 300 judges that the selected area is in the plant competition step (F) when the on-land plant native to the selected area is identified using the plant judging unit (200).
