Abstract Many resilience surrogate measures have been established to evaluate the performance of water distribution systems (WDSs) over past three decades. However, most those neglected nexus between network layout and essential features system resilience. In this paper, we proposed two novel by introducing node degree pipe diameter uniformity within extended nodal neighborhood in a rational, mathematical structure. Then, comparison framework was developed, which included multi‐pipe failure scenario generator dual‐perspective evaluation method. New were benchmarked with well‐known counterparts on four networks different numbers sources loop degrees. Results revealed that new outperformed existing ones clearly marginal computational budget increase. Solutions derived from strengthened increasing uniformities critical nodes. Additionally, showed fewer fluctuations. This study provides insights into how maintain more resilient WDSs.

Various reliability surrogate measures have emerged over the last three decades to design water distribution systems. However, existing comparative studies cannot assess from resilience perspective considering dynamic absorption–recovery process imposed by pipe failures. In this work, we propose a novel benchmark framework based on global analysis examine measures’ performance. Surrogate were compared via stress–strain curve derived under extended period simulation. particular, identify comparable stress range articulate differences among and significantly reduce computational burden. Then, develop normalized score (NRS) evaluate quality of solutions network design. Five well-known are for multiobjective two networks. Results show that Network Resilience Index achieves 2.5% 10.1% better NRSs than mean five measures, implying both nodal surplus energy diameter uniformity greatly impact system’s resilience. The diameters is more significant flow rate. Our findings contribute new evaluation.
