Preface
With the development of the society, the impact of human activities, flood disasters is becoming more and more frequent accidents. It has heavily damaged people’s life and property.
Adhere to “prevention in advance, combining prevention with control", we must establish a mountain water conservancy project which can prevent flood disasters system including forecasting, early warning capability and emergency command
ability .So that we can protect people’s lives and property after getting the early warning information.
Second, the project analysis
2.1 System components
Hydrology and watershed management, flood control and monitoring system by the center, sub-centers (county and city) stations, field units constitute a set of three hydrological telemetry network. The completion of the system will improve the hydrological information collection, transmission and processing methods, data collection and reduce the time required to forecast operations， improve the reliability of information collection and transmission, information processing capabilities to improve flood control basin.
