Due to climate change, water shortages and water‐related disasters will be serious. Since the damage and frequency of drought are increasing, the importance of water resource management technology is increasing. In this study, we analyzed the amount of greenhouse gas and the environmental impact caused by the production and operation system technologies of movable weir among various water resource management technologies. The research subjects were air inflatable rubber dams widely used in rivers and upright type rubber dams, which are an improvement on the existing rubber type. Each type of dam was studied at sizes of 1,500H×10,000L mm and 3,000H×20,000L mm, and the two types and two sizes were compared and analyzed. Using life cycle assessment, we examined the environmental impacts using the amount of electricity required for operation and the discretionary amount required for production. In the ʹ1,500H×10,000Lʹ dams, the global warming indexes were 9.35E+04 kg CO2‐eq. for upright type and 7.36E+04kg CO2‐eq. for inflatable type. At size of ʹ3,000H×20,000Lʹ the global warming indexes were 9.09E+05 kg CO2‐eq. for upright type and 1.07E+06 kg CO2‐eq. for inflatable type. Analysis of the life cycle environmental impact showed that the environmental impact of the air inflatable rubber dam was reduced by 39.8% at ‘1,500H×10,000L’ compared to the larger size. At the larger ʹ3000H×20,000Lʹ size, the upright dam showed a 10.1% smaller impact than the air inflatable rubber dam. Selection of water resource management system should consider climate change, not only management purpose and cost. Additional studies and improvements on rubber dam systems should be made.
