Geographic Information System for Water Management
Defining Issue: I n water management not only is operational water management of great concern, but the maintenance of water systems (embankments, structures, canal systems, etc.) is important as well. Regular safety tests have to be drawn up on components of the water system. The actual condition of each component has to be compared with the requirements. Therefore, the actual conditions of the water system have to be monitored continuously to gain insight into necessary maintenance. GIS Solution: Much information has to be gathered and stored before any calculations can be made. The responsible authorities have already stored much information in automated information systems. Alphanumerical information on land registration is mainly stored on the AS400 platform. For the graphical information mostly AutoCAD is used. Methodology: Information on the conditions of the water systems was mainly stored in paper archives or local databases. Therefore, an application was built for structured, automated,
user-friendly registration of management information that could use the existing automated information. Advantage was taken of the use of a geographic information system because lots of graphical data (AutoCAD) had to be linked to alphanumerical data (dBASE, AS400). Software: The application was written using AutoLISP (AutoCAD, ArcCAD), Avenue (ArcView), and DDE (ArcView and Rumba).
