　　Abstract：In view of current problems that flood control and disaster reduction business process and digital baseplate are incomplete, development of digital twin scenarios is difficult, and decision-making support is inadequate, this paper analyzes key technologies such as one-stop flood control process development, digital twin scenario realization, development of flood control knowledge system. The requirements of digital platforms are defined by applying these key technologies, to develop a digital twin basin flood control “Four-Pres” platform, which is based on the overall requirements of the Ministry of Water Resources. The platform has realized a one-stop flood control with closed whole process, from basin forecasting and early warning, situation judgment, decision-making, operation, regulation to emergency rescue support. The “Four-Pres” platform has been launched in the Qiantang River Basin in Zhejiang, the Baiyangdian Basin in Xiong'an, the Sihe River Basin in Jining and Jialu river in Zhengzhou. The practical application shows that the platform helps to improve the “Four-Pres” capabilities of flood control in the basin, and plays an important role in improving reservoir detention, ensuring dam security, improving rescue efficiency, and reducing casualties and economic losses, which has certain practical value.
