The Columbia River is the fourth largest river in North America. Report of A.G. Crook Company to Bonneville Power Administration, Portland, OR. Primary support for the project was provided by WDOE, with additional major support provided by the BPA, NWPCC, BCME, OWRD, and CTED via the 2009 WACCIA (http://cses.washington.edu/cig/res/ia/waccia.shtml) (Miles et al., Citation2010). Following the WACCIA in 2009, the WA Legislature, via the Act relating to State Agency Climate Leadership (2009), charged WDOE and other state agencies with preparing a first climate change adaptation plan for WA. Crook, A. G. (1993). The study was also unique in that this was the first time that these agencies had run their own reservoir operation models to assess climate change impacts in the CRB, an element of the study design which greatly increased the impact of the study conclusions in the agencies involved. Northeast wind 5 to 10 mph. The Columbia River basin will see an increase in flooding over the next 50 years as a result of climate change, new modeling from Oregon State University indicates. The Columbia Basin Climate Source is your one-stop destination for information about climate change, impacts, and action in this region. In addition, some observed streamflow data are suitable for use as natural data if the effects of storage and diversions are relatively small (e.g., for the USGS Hydro-Climatic Data Network streamflow sites). Extreme event statistics are calculated directly from the raw (i.e., not bias-adjusted) daily streamflows at each streamflow site, applying methods developed by Hamlet and Lettenmaier (Citation2007) and Mantua et al. Atmosphere Ocean 51. The state of Oregon, for example, is classified as about 75% mixed-rain-and-snow for the twentieth century climate. 2013a. Gusts up to 20 mph in the morning. The authors would like to acknowledge the contributions of two anonymous reviewers and the lead and associate editors for Atmosphere-Ocean, whose constructive suggestions substantially improved the paper during the review process. The Columbia River is the fourth largest river in North America and the largest river in the Pacific Northwest. Changes in the 1 April snowpack have been shown to depend strongly on winter temperature regimes (Hamlet, Mote, Clark, & Lettenmaier, Citation2005; Mote, Citation2006; Mote et al., Citation2005). 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. But as researchers continue to fine tune climate models, shifting demand for water now must be accounted for, say Washington State University scientists. The CBCCSP was designed from the outset to support users with a very wide range of technical sophistication and capacity. Based on these substantial differences in hydrologic impacts it is difficult to escape the conclusion that management of water resources in the Canadian portions of the basin will play a crucial role in the ability of US water managers to adapt to more substantial changes in streamflow timing and summer low flows in the United States. In relatively small basins (approximately 5001500km2), of which there are a substantial number included in the study, errors in meteorological driving data are often a strong determinant of simulation errors. 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. Exploring a Large Ensemble of Simulations Across a Diversity of Hydroclimates. Three statistical downscaling approaches were selected or developed for the study: Composite Delta (CD): regional average projections compiled from 10 GCMs (Elsner et al., Citation2010), Bias Correction and Spatial Downscaling (BCSD): (Salath, Citation2005; Salath, Mote, & Wiley, Citation2007; Wood, Leung, Sridhar, & Lettenmaier, Citation2004; Wood, Maurer, Kumar, & Lettenmaier, Citation2002), Hybrid Delta (HD): (Hamlet et al., 2010a). Source: Bonneville Power Administration. Tague, Grant, Farrell, Choate and Jefferson (Citation2008) showed analogous differences between watersheds in the PNW based on the relative contribution of groundwater to base flows. Implications of global climate change for snowmelt hydrology in the 21st century, Modeling snow accumulation and ablation processes in forested environments, Uncertainties in hydrologic and climate change impact analyses in headwater basins of British Columbia. Highs in the lower 80s. Lee. A key design element of the CBCCSP from the outset of the project was to produce a well-organized and well-documented end-to-end (i.e., GCM to hydrologic products) data processing sequence and a web-accessible data archive that would greatly reduce the cost of producing updates in response to each subsequent CMIP/IPCC cycle. All of the meteorological forcing data, except wind speed, are reproduced in the output files produced by the hydrologic model. Most of the fundamental details regarding the VIC implementation used in this study are covered by Elsner et al. Among its most useful features is the predominantly physical basis of the model, which largely avoids concerns about parameter stationarity in a changing climate. These data are summarized in figures and tables prepared for each streamflow site discussed in Section 4. The DOI via the USFWS has recently established a set of LCCs across the United States (USFWS, Citation2013) and has generated additional funding to support a group of regional CSCs, one of which was recently established in the PNW (PNWCSC), combining the efforts of about 15 PNW research universities, jointly led by the USGS, Oregon State University, the UW, and the University of Idaho. Changes in PET (PET3, see Table 2) and AET (see Table 2) are shown in Fig. Daily and monthly streamflow for each streamflow site are provided in two formats: a) raw VIC simulations, and b) bias-adjusted simulations. The WDOE was also directed to incorporate climate change explicitly in these comprehensive assessment efforts. As mentioned above, 20062007 was something of a turning point for regional stakeholders considering future actions to prepare for climate change. The magnitude of flooding the term used to describe flooding severity is expected to increase throughout the basin, which includes the Columbia, Willamette and Snake rivers . Thus, depending on their needs and level of technical sophistication, stakeholders can make the best use of the study products by extracting information at different points in the data processing sequence, all of which are available on the study web site. Peak flows actually increase at many sites in Canada because of increasing fall, winter, and spring precipitation in this part of the domain, although the peak flow also occurs about a month earlier. The choice of the A1B scenario, however, was informed by the authors viewpoint that this scenario is an instructive and plausible scenario reflecting relatively little GHG mitigation until mid-century (similar to A2 until about 2050), followed by more effective GHG mitigation efforts in the second half of the twenty-first century as impacts intensify. Schnorbus, M. A., Bennett, K. E., Werner, A. T., & Berland, A. J. The site at Corra Linn Dam on the Kootenay River is representative of changing hydrographs in many locations in the northern tip of the CRB in British Columbia. These emerging needs ultimately led to the CBCCSP, and similar efforts in BC led by PCIC (Werner, Schnorbus, Shrestha, & Eckstrand, Citation2013). Tonight Mostly cloudy. The climate of the high mountain regionsthe pramos, ranging from about 10,000 to 15,000 feet (3,000 to 4,600 metres)is characterized by average temperatures below 50 F (10 C), fog, overcast skies, frequent winds, and light rain or drizzle.

This advance through the native forest has been driven, primarily, by cattle ranching. The presence of glaciers in Canada (not included in the CBCCSP simulations) may further exacerbate the discrepancies between impacts to summer flows in the United States and Canada in late summer (Werner et al., Citation2013). A detailed climate change assessment report was prepared by the CIG for Seattle City Light (Snover et al., Citation2010) based primarily on the CBCCSP database. The Assessment will result in a better understanding the potential impacts of climate change on the eight components identified in SECURE in the Columbia River Basin.

To select an appropriate group of specific streamflow locations to include in the study to meet these diverse needs, the primary funding agencies for the study and several other key water management agencies in the region (MDNR, IDWR, USBR, and USACE) were asked to submit prioritized lists of streamflow locations. These products are based solely on the CD and HD projections listed in Table 1. The city's average temperature is 57 F (14 C). This study represents one of the first attempts to dynamically couple a sophisticated, physically based hydrologic model with a detailed crop model to estimate the integrated impacts on water supply and crop viability at a range of spatial scales.

Columbia Basin Care is the region's only independent nonprofit skilled nursing facility for long-term care and short-term rehabilitation. Hydrologic climate change scenarios for the Pacific Northwest Columbia River basin and coastal drainages. The Assessment was initiated in June 2013 and is expected to completed in December 2015. Using the VIC model, the study has projected impacts for the Great Busin and the Columbia River, Missouri River, and Colorado River basins, and assessment of impacts in California is underway at the time of writing. Yakima River Basin Study The results were only slightly better than those achieved in the large-scale calibration. These include the following: Columbia River Basin Impact Assessment: Reclamation conducted the Columbia River Basin Impact Assessment to evaluate the potential effects of future climate change on river flows at 158 locations across the basin.
