Micropolis: A Virtual City for Water Distribution System Research Applications
MetadataShow full item record
For security reasons, cities keep their water distribution system data confidential. This data includes geographic layout of pipes, tanks, pumps, wells, buildings, and demands. While the secrecy of water system data is crucial, it poses a difficulty for research on water distribution systems as results can not be publicized. Therefore, a library of virtual water distribution systems can be an important research tool for comparative development of many analytical methods. A “virtual city” has been developed, including a comprehensive water distribution system, as a first entry into such a library. “Micropolis” is a virtual city of 5000 residents fully described in both geographic information systems (GIS) and EPANet hydraulic model frameworks. To simulate realism of infrastructure, a developmental timeline spanning 130 years was described, and this timeline is manifested in items such as pipe material, diameter, and topology. Examples of using the virtual city for simulations of contaminant spread are presented, and future applications will include fire flow and water auditing. The data digital files describing Micropolis are available from the authors for others’ use. It is hoped that other virtual cities will follow for the use of the research community.
