System Overview

Medium and Small Rivers’ Hydrological Monitoring System includes flood forecasting and early warning system and hydrological service system. Flood forecasting system’s construction content mainly includes basic data’s acquisition and analysis, forecasting model and method development, flood forecasting scheme’s establishment, flood forecasting system’s software platform development and forecasting special database’s construction, etc. Hydrological service system’s construction content mainly includes rainfall information sharing and transmitting, and information quality monitoring system’s construction, hydrological service system’s software platform development, flood control and drought dedicated special database’s construction, etc.

System Principle

(1)Practicability

The system takes meeting the medium and small river’s flood early warning and forecasting as the highest requirement. All the development and use of the design take the actual business needs as the starting point. The developed software system platform should meet the regional storm flood characteristics and engineering properties, and should meet the actual work needs.

(2)Advancement

Strive to advance in practical conditions, the technique and self-developed software and model should seek practical starting point and advanced technology in the practical premise, and should adapt to the future technology development’s trend, which can ensure that the system has openness, scalability and a longer probation period.

(3)Openness

Adopting open structure system design makes the system has the scalability of the software and hardware environment, which can constantly add new operation functions and new information during the running process.

(4)Inheritance

Making full use of the existing model, data and application resources; not to engage in or minimize duplication of construction and development; focus on the system’s characteristics of easy operation and standardization.

System Features

●According to the real-time water and rainfall data in the hydrological database, the system can realize multi-job calculation of the hydrological forecasting model, can analysis and synthesize the forecasting results.
●With comprehensive analysis functions, such as strong real-time correction of the interactive modification, the system can achieve the organic combination of computer technology and flood forecasting technology. The system has the functions of using rainfall to comprehensive analyze information and simulating the change of hydrological in different rainfall level.
●With relatively perfect real-time water and rainfall regime information, weather information and historical flood data retrieval functions, the system strive to closely combine the graphics technology and data.
●The system can automatically preprocess the real-time hydrological database, and generate the forecast using hydrologic data, and the system has certain data interpolation error correction function.
●Allow users to interactively specify different forecasting models and combine different forecasting methods in different forecasting stations. When forecast the users’ operation, according to the need to choose whether or not to take expert interactive modification. And the system has the function of adding new forecasting method library.
●User management function, the system administrators manage the users, which include users’ creation, deletion, permission, rights assignment changing.
●Software system should be simple operation, and have friendly human-computer interaction interface.
