Impact/Purpose:
Water distribution network models for large municipalities have tens of thousands of interconnecting pipes and junctions with complex hydraulic controls. Many water security applications require detailed simulation of potential contamination incidents. Sometimes these simulations produce impact arrays so large that sensor placement optimization requires more memory than is available on standard desktop computers. Large networks can be skeletonized to reduce computation; however, this alters network hydraulics and, therefore, sensor placement. We evaluate a two-tiered sensor placement approach that combines detailed network hydraulic simulations and subsequent geographic aggregation to reduce memory requirements. In this paper, we compare the two-tiered sensor placement approach to results using the all-pipes network and skeletonized networks.
