Abstract: Climate change will change the service environment of water conservancy projects. As one of the main construction materials for water conservancy projects, hydraulic concrete is more sensitive and fragile to extreme climate condition. The observed influences of low temperature, cold wave and drought on China’s hydraulic concrete structures were summarized. Considering future climate change and its potential impacts on construction materials of water conservancy projects, the adaptation measures for improving properties of hydraulic concrete and guaranteeing safety of water conservancy projects during the different stage of design, construction and operation of water conservancy engineering were addressed. From the point of view of plan revision and formulation, monitoring and forecasting, the response measures to deal with climate change in the field of flood control safety and water resources security were also analyzed in this paper.

Key words: climate change, water conservancy projects, hydraulic materials, impacts, adaptation measures
