Abstract :
The hydrologic information is the foundation of the hydrologic researches. At first, this paper analyzes hydrologic information system and hydrologic data sharing in the current status. Based on the data collecting and integrating of the Heihe River Basin including the spatial data and the observation data, hydrologic data sharing and on-line services are realized with the help of open source HIS (Hydrologic Information System) by CUAHSI (Consortium of Universities for the Advancement of Hydrologic Science, Inc.). The entire HIS for the Heihe River Basin adopts the ODM (Observation Database Model), WebGIS and Web service using the watershed science data from the Heihe River Basin. Therefore, a hydrologic information sharing was established with such functions as hydrologic observed data retrieval, browsing, online service and analysis by an application case in the Heihe River Basin, a typical inland river in the northwest China.
