Establishment and application of the information management system model for regional water resources

A regional resource information management system was developed to improve the water utilization and distribution in regional water systems. This paper took Langao village of Longkou city as an example to optimize allocation of water resources. The system integrates rainfall amount frequency analysis model, industrial, living and ecological environment water demand real-time forecast model, water resources supply and demand balance analysis model, surface water and ground water conjunctive operation model. It was found that the model can reasonable allocate regional water resources, and relieve the contradictions between supply and demand in space and time. The model provides us a new method and thought for evaluating of water resources sustainable utilization.
