Peng Ao assiduously studied the theory of river regulation, summed up the experience and lessons of predecessors, put forward the basic proposition of "opening the estuary and blocking six dams" and the idea of "using the Yellow River to transport the economy and the Huaihe River to brush the Yellow River", adopted the practice of "building dikes to control water and attacking sand with water" and made a major breakthrough. Peng Ao also wrote the experience of river management into ten volumes of the Book of River Management, which has irreplaceable value in the history of water conservancy in China. China's special chapter on water conservancy history spoke highly of it: "This is not only a great contribution to the national economy and people's livelihood, but also one of the most advanced water conservancy projects in the world in terms of its scientific level."
