Construction of water supply pipe network based on GIS and EPANET model in Fangcun District of Guangzhou

With extensive use of GIS technology in the field of water resources management and river basin water environment simulation, it has unique advantage of data accurately management and expression, and integration of data operation and spatial analysis, becoming important basis for urban infrastructure planning. Pipe network extraction, DEM elevation extraction and pipe network simplification have done based on the powerful pre-treatment system of GIS software platform, and second development is done based on ArcEngine of GIS technology, coupled with EPANET pipe network model, water supply pipe network model in Fangcun District of Guangzhou is developed based on GIS technology and EPANET model, provides model basis for further research on water quality monitoring.
