CHENGDU, CHINA

Nestled in the heart of China’s Southwest, Chengdu is not only a gateway to cutting-edge advancements in hydraulic engineering but also a vibrant cultural gem that enchants visitors from around the globe. Chengdu’s profound connection to water management spans millennia. Just 50 kilometers from the city lies the Dujiangyan Irrigation System, a UNESCO World Heritage Site and a marvel of ancient engineering.
Built in 256 BC, this ingenious project transformed the Min River’s turbulent flows into a lifeline for Sichuan’s fertile plains, showcasing sustainable water governance that remains operational today. As a hub for modern hydropower innovation, Chengdu sits at the doorstep of China’s most dynamic hydropower corridors, where towering dams and renewable energy research thrive alongside the region’s rivers and mountains. This unique blend of ancient wisdom and modern technology makes Chengdu an inspiring backdrop for discussions on resilient water infrastructure and climate adaptation. Read more

Sichuan University is one of China's top universities. It is located in Chengdu, a famous historical and cultural capital city of Sichuan Province. It consists of three campuses: Wangjiang, Huaxi and Jiang'an. It was not only one of the first universities in the western tradition, but also one of the pioneering universities to offer postgraduate programs in China. Read more
The State Key Laboratory of Hydraulics and Mountain River Engineering, as one of the earliest labs in China that engages in the research of inland water resources and hydropower engineering, was constructed in 1988. Currently, the major focuses of research of the laboratory include 1) mountain river evolution and function protection, 2) mountain river ecological conservation and management, 3) mountain river disaster prevention and risk control.
