“…Revetment methods that are already being used are not verified if appropriate for river conditions in many cases. Most research has been conducted on the vegetation, stability, vertical velocity distribution, and calculation of flow distribution in relation to flow resistance in the river [2,3,4,5].…”

Applicability and hydraulic evaluation of green revetment media which have improved physical structure are evaluated by the hydraulic model experiments. Results of the study on the relative erosion rates of base materials by the location of method and presence of vegetation, the green revetment had stability up to the limit of 1m distance, 1.5kg/m2 water pressure and 2 min of experimental duration. In addition, maintaining good rooting of vegetation would be beneficial to prevent erosion of revetment media during the flood as the resistance to the water pressure increases when the vegetation is applied in the river revetment.

In recent years, river maintenance projects using natural methods have been continuously implemented in urban areas and methods emphasizing ecology are being developed and constructed in revetment areas. However, there is insufficient technical review on the hydraulic stability of those revetment methods during the event of flood. Therefore, a hydraulic analysis is necessary for the stream where revetments are applied.This study was conducted to develop an objective test method for the hydraulic stability of green revetment media. For this purpose, hydraulic model tests were performed for the green base materials for revetments. 권효진․김성희․구본학higher corrosion resistance in non-vegetation condition compared to dry green revetment media, and the loss of base materials by the rooting of vegetation showed significant reduction by the vegetation.In addition, results of the allowable tractive force of the base material indicated it is relatively stable in vegetation condition but scouring can occur in non-vegetation condition. Therefore, the development of vegetation in revetment areas is anticipated to be effective for the stability of revetment areas by reducing external forces interacting with the corrosion resistance and stream bank. The green revetment media in expected to contribute to the stability of revetment areas.
