Abstract :
[en] Skeletonization techniques enable speeding up computations of water distribution networks(WDN). It is of particular interest when a high number of model runs is necessary, such as for optimizing the positioning of sensors or micro-turbines. However, the accuracy of various skeletonization methods was rarely assessed considering a broad range of operation conditions of the network, i.e., under a wide spectrum of water supply and demand scenarios. Most previous studies compared the predictions of the original and skeletonized networks based on a limited number of representative cases. Here, we use a Monte-Carlo approach to assess skeletonization methods under a high number of water supply and demand scenarios. The scenarios are generated from stochastic variations in the time evolution of water supply to the network, and variations in both the time evolution and the spatial distribution of water demand. The considered skeletonization methods involve merging of series pipes, iterative removal of pipes in dead-ends, and removal of pipes using a diameter-based or a discharge-based threshold. The developed methods were applied to a real-world WDN with synthetic boundary conditions. This enables comparing the outcomes of the proposed Monte-Carlo approach for assessing the reliability of network skeletonization to the outcomes of a more conventional approach.
