Abstract: Until now, levee repair and reinforcement technologies applied to rivers have been easily washed away and destroyed by sudden floods, and have had a negative impact on aquatic ecosystems. Therefore, it is necessary to develop levee repair and reinforcement technology that strengthens hydraulic stability and is environmentally harmless. The technology applied in this study is an eco-friendly levee repair and reinforcement technology that utilizes biopolymer, a non-toxic material. In this study, the hydraulic stability of this technology was examined. The results of the limit flow rate and allowable tractive force experiment showed that the flow rate was 8.0 m/s and the maximum tractive force was 67.25 kgf/㎡ (659.05 N/㎡). In addition, the results of the vegetation loss rate experiment confirmed that there was no vegetation loss from 75 to 85% of the total vegetation cover area at a flow rate of 8.0 m/s. It was confirmed that it is more hydraulically stable than the technology applied to existing rivers.
