With the completion of the first-stage project of national flood control and drought relief command system,the yellow river conservancy commission ( YRCC ) has finished the construction of hydrologic information collecting system and computer network system, and built ten regimen canters including YRCC hydrographic office,Yanan and Jinan etc. In order to further improve the quality of hydrologic information and accelerate information processing speed, it is necessary to construct an open, secure, high efficient hydrologic information forecast network system based on B/S mode. With the help of the Web model, the system will ensure the station reports to send the office of state flood control and drought relief headquarters accurately in real time,which can improve the efficiency of forecast station and reduce the work intensity of the staff and contribute to the integral improvement of the yellow river hydrologic information reports quality.
