In response to severe flooding and to ensure electrical power generation, China built the Banqiao Dam in the Huai river basin of the Henan province. It was completed in 1952. However, they never imagined the dangers that would follow.  Due to construction and engineering errors, numerous cracks in the dam appeared after completion and were repaired by Soviet engineers. Chen Xing, one of China’s foremost hydrologists, was involved in the design and was a vocal critic of the dam’s final construction as well as the government’s policy. Chen had recommended twelve sluice gates for the dam, but only five were installed. Chen was involved in other dam projects, but due to his continuing voicing of safety concerns related to design and construction practices, he was removed from the projects.
