Summary
This review examines the multiple sources of uncertainty affecting hydrologic climate change impact assessments, as suggested by the authorship and journal focus. The paper characterises how uncertainties from global climate models, regional downscaling techniques, and catchment-scale hydrologic models compound to affect projections of future water availability and extremes. Understanding and communicating these uncertainties is presented as essential for robust water resource planning under climate change.
UK applicability
The methodological framework for uncertainty characterisation has direct relevance to UK hydrologic impact assessments and water resource management planning. Similar uncertainty quantification approaches would apply to UK catchments, though specific climate model ensembles and downscaling methods differ between US and UK contexts.
Key measures
Uncertainty quantification in hydrologic projections; climate model spread; downscaling uncertainty; hydrologic model sensitivity
Outcomes reported
The study characterizes sources and magnitudes of uncertainty in projections of climate change impacts on hydrologic systems. It examines how uncertainties from climate models, downscaling methods, and hydrologic models propagate through impact assessments.
