Having analyzed the problems in traditional C/S-model-based flood forecasting system, we designed a novel development framework for B/S model flood forecasting system based on Silverlight. According to the development targets, we put forward the general structure of the forecast system for reservoir flood, and expounded the key technology in the development environment. Moreover, we analyzed the solutions of core functions such as system security, cross-domain access strategy, flood forecasting module design, data operation class and interactive operation of graph, among which for the flood forecast module we adopted standard dynamic link libraries to provide call interface. By using Silverlight technology and the Visual Studio 2010 integrated environment, we developed the system with functions of four modules. This forecasting system has advanced technology, user-friendly interface, sensitive response, steady operation and good portability and scalability. Practical application shows that the system has better user-friendliness and interactivity than existing B/S system, and also has promotion value and application prospect in water conservancy industry.
