According to the current situation that the hydrologic data collecting system has rapidly developed in Zhejiang Province,a timely,accurate,visual and real time system,which can issue real time hydrologic information and forewarning,was designed and developed by using Browse/Server construction,and technology including ArcIMS,XMI,database,network and space-time visual.

Based on the WebGIS technique and MapX,this paper discussed the application of WebGIS into real time hydrologic information service system in Jiangxi Province.

Elementary talk on security and management of the water regime information database;

According to data transmission requirements of real time & periodicity for water regime information transmission, and characteristics of small amount system data transmission, a water regime information transmission system is introduced based on GPRS technology in this article.

Combining with the design and building of water regime information collection and transmission system of the system, the paper introduces the principle and function of the composition of water regime forecasting system and remote terminal unit (RTU) and the application of data collecting terminal specially used for hydrologic forecasting YSCADA-1 in water regime information collection and .

Transmission of hydrological information between hydrological station and hydrological information branch center is a bottleneck for the hydrological information system concerned;for which the composition,function,characteristics and the application prospect of the information transmission system adapted to the Standard for Hydrological Information Code are described herein.

The techniques of SAPI and GSM short information are used to realize the release of real-time hydrological information and the function of on-site voice warning and prompt, thus strengthening the long-distance surveillance and on-site surveillance of hydrological information.

The real time flood control hydrological information transmission system in the Huaihe River Basin was built by a public packet switching data network which is a new technology, and has been supplied by post and telecommunication bureau recently and widely appliced abroad as a communication medium.

The water information processing system of Shaanxi Province is one of integrated network information processing system, it is based on software and hardware Applying the system,we can transmit and manage real-time water telegraph It have improved water information work modern step for Shaanxi Province in using the syste

According to data transmission requirements as real time and periodicity for the water information,and characteristics of small amount system data,a water information transmission system is introduced based on GPRS(General Packet Radio Service) technology.

The scheme of the real-time hydrographic scheduling and joint computation is designed for rapid and precise analysis of hydrographic circumstance and flood trend forecast, which is combined with the flood control and disaster mitigation in the Qing River Valley.
