Development and application of the information management system for regional water environment

A regional environmental information management system was developed to improve the water distribution and utilization in regional water systems.The system can also predict accident possibilities and assist emergency planning.The system integrates geographical information system technology with the water management system in a parallel design having a functionality layer and a data layer.The system integrates a relational database management system,geographical information system,and artificial neural network water quality prediction model.The system provides visualization of the regional water environmental information and decision making support based on the threshold alarms.
