Abstract：The Danjiangkou Multi-purpose Dam Project plays a key role for integrated development and management of the Han River Basin.As the water source of the Middle Route of the South-to-North Water Diversion Project,the Danjiangkou faces great challenges to control flood and supply water,due to the high requirement of hydrological and water resources forecasting and scheduling.Introductions are made on technical progress and application in the Han River Basin since the operation of the South-to-North Water Diversion Project.In terms of the construction of"three defense lines"for rainwater monitoring and forecasting,the first line is to strengthen radar shared monitoring,build a radar warning platform,and conduct multi-mode dynamic integrated forecasting;the second is to achieve full coverage of flood forecasting system,create a distributed hydrological simulation system,boost innovation of intelligent forecasting methodologies and establish a new method matrix for hydrological forecasting;the third is to understand changing of laws,develope intelligent reasoning technology for reservoir scheduling,independent intellectual property CJH hydrodynamic models,and real-time flood control reverse calculation tools.In terms of prediction and flood resource utilization,based on multi-dimensional driving model method,it aims to improve medium and long term water volume prediction,and dynamic control and operation of water level of the Danjiangkou Reservoir during the flood season.In terms of platform construction,it is planned to build big data information platforms,a CJH professional model market,and a forecast and dispatch system for the basin.Discussions are also made on the supporting role of real-time flood control and water supply scheduling in the water source area over the past 10 years and future prospect of enhancing the level of medium and long term forecasting and scheduling,and joint scheduling of reservoir groups.
