Abstract: By using the embedded development technology, a geographic information management system for riverway was developed. Visual Studio 2005 and ArcEngine 9.3 component were used as development tools, and the SQL Server 2005 was taken as the DBMS (database management system) for the spatial and attribute database. Functions of thematic queries, analysis, statistics and updates for hydraulic engineering information, water environment information and flood control information were offered, and the user management and auxiliary operating functions were strengthened. By using this system, scientific information management for riverway resources data was achieved. The system has been applied to the information management of Sanchuan river watershed and has been working stably.

Key words: Visual Studio, ArcEngine, information management system for riverway, Sanchuan river
