A new publication in the journal Environmental Modelling & Software ( Srivastava et al., 2026 ) describes a new model, PSI-Cascade, to couple stormwater flooding and power outages for the analysis of cascading infrastructure failures, with an application to Phoenix, Arizona. Congratulations to the authors associated with the Center for Hydrologic Innovations ! Abstract: Urban infrastructure is typically designed in isolation, neglecting system interdependencies and the effects of spatiotemporal variability of climate forcings across systems. Here, these limitations are addressed by developing the PSI-Cascade Python-based framework, which simulates cascading failures from power to stormwater infrastructure under high-resolution space-time wind gust and precipitation forcings. PSI-Cascade couples open-source, spatially explicit stormwater and power infrastructure models and represents cascading failures on stormwater pumping stations caused by wind-induced power outages through user-defined fragility curves, linking wind gusts with the transmission line failure probability. Using Phoenix, AZ as a case study, it is shown that PSI-Cascade adequately captures the spatiotemporal variability of documented street flooding, particularly around pumping stations that likely stopped operating due to wind-triggered power outages. The case study also highlighted the importance of parameterizing the fragility curves based on local failures. The PSI-Cascade framework is a valuable tool for increasing urban flood resilience.
