The CBCCSP provided climate change projections of meteorological drivers and a calibrated VIC implementation in support of the study. 2860, 59th Legislature (WA 2006). Thanks to Shrad Shukla, at the UW for 1/16 degree VIC model calibration over the Yakima basin. Climate Adaptation | Columbia Basin Rural Development Institute The HD method was also selected as the basis for the main summary products derived for each river location (see description below), primarily because it was capable of providing good performance over the complete range of products produced by the CBCCSP (Hamlet et al., 2010a). Among its most useful features is the predominantly physical basis of the model, which largely avoids concerns about parameter stationarity in a changing climate. Lows in the upper 30s to lower 40s. Flooding in the Columbia River basin expected to increase under climate change Date: February 10, 2021 Source: Oregon State University Summary: The Columbia River basin will see an increase. Thus, each site is bias-corrected using either naturalized or modified flow but not both. Right panel: Historical and projected future watershed classification (rain-dominant, transitional (mixed-rain-and-snow), snow-dominant) for 10-digit Hydrologic Unit Code watersheds, based on the long-term mean of the SWE2PR for each watershed. The same procedure is followed for estimating extreme low flows, except the lowest 7-day flow is extracted for each water year, and 7Q10 (the extreme 7-day low flow with a return interval of 10 years) is estimated. Climate Change Impacts on the Columbia Basin Those who lack their own hydrologic model, but wish to make additional runs themselves, can obtain the calibrated VIC model implementation.

These parameters were chosen because they strongly affect the timing and volume of runoff production in the model simulations and are, in general, not available from observed data.
