Summary
This modelling study, published in Nature Climate Change in 2018, examines projected changes in rain-on-snow flood hazard across western North America under climate warming scenarios. Using high-resolution climate simulations, the authors project increases and poleward/elevation shifts in rain-on-snow flood risk as suggested by mid-to-late 21st-century climate projections. The work has implications for water resource management and flood preparedness in snow-affected regions.
UK applicability
Limited direct applicability, as rain-on-snow flooding is not a primary flood mechanism in the United Kingdom. However, the methodological approach to climate-driven hydrological risk projection may inform UK flood risk assessment under future climate scenarios, particularly in upland regions with winter precipitation.
Key measures
Rain-on-snow flood frequency, magnitude, spatial distribution, and temporal shifts under future climate scenarios
Outcomes reported
The study projected changes in rain-on-snow flood frequency, magnitude, and timing across western North America using climate model simulations. It assessed shifts in flood risk as a function of projected warming and precipitation changes.
