Abstract

We analyzed and updated peak flow projections for Washington state using a new streamflow projection dataset: The River Management Joint Operating Committee’s version 2 hydrologic projections (RMJOC-II, https://www.hydro.washington.edu/CRCC, Chegwidden et al. 2019). This new dataset assesses future changes for multiple climate models, downscalings and hydrologic modeling approaches. Based on the findings we provided recommendations for estimating the central tendency and uncertainty of this dataset and discussed the benefits and drawbacks of different regionalization schemes.
