Abstract: In the light of the deficiencies in major river basin flood control forecasting and dispatching platform of China at present, such as low data processing efficiency, weak resources share ability, insufficient general degree of software and incomplete three-dimensional function and so on, based on the network service concept of big data platform, the integrated flood control forecast operation system for basin is designed and developed. This paper presents the overall design and the key technologies. The key technologies of the system include object-oriented big data encapsulation, generation of topological relations in river network spaces, contract mode network service construction and mass data transmission based on JSON. The reliability, practicability and scalability of the system are verified in the flood control forecasting and decision-making of the Yangtze River Basin.
