These emerging needs ultimately led to the CBCCSP, and similar efforts in BC led by PCIC (Werner, Schnorbus, Shrestha, & Eckstrand, Citation2013). The CBCCSP also provided a more thorough assessment of hydrologic extremes via the HD scenarios, providing ranges of these values that were more geographically specific as opposed to an estimate of the central tendency from the CD approaches used in the WACCIA. completed or are ongoing in the Columbia River Basin. It reaches a thickness estimated at 16,000 feet in places. However, our goal in this case was not to reduce the range of uncertainty by selecting a smaller group of GCMs. Hamlet, and S.-Y. These areas are so cold in winter (DJF average on the order of -10C temperature) that a change in temperatures of 23C has relatively little effect on seasonal snow accumulation in the 2020s and 2040s. In 2021, these livestock operations alone accounted for 75% of deforestation on public lands, according to a study by the Amazon Environmental Research Institute (IPAM).. Climatic Change 113:499-524. Precipitation Regression on Independent Slopes Model (Daly et al., Extreme daily high flow value with a 20-year recurrence interval (20-year flood), Extreme daily high flow value with a 50-year recurrence interval (50-year flood), Extreme daily high flow value with a 100-year recurrence interval (100-year flood), River Management Joint Operating Committee. 95 0 obj <> endobj Registered in England & Wales No. Uniqueness is also evident by looking at the Columbia River Basin. Bias-corrected streamflow values are useful in water planning studies, especially for providing inputs to reservoir operations models that are calibrated on a particular naturalized or modified flow dataset (e.g., Hamlet, Lee, et al., Citation2010b; NWPCC, Citation2005; Vano et al., Citation2010). These extensive and ongoing research activities have also been materially supported by the long-term outreach and education programs of CIG, which have, from the outset, fully recognized the transboundary nature of the CRB (Hamlet, Citation2003; Miles et al., Citation2000) and responded by promoting sustained, long-term interaction with CRB researchers and stakeholders in the United States and Canada (Hamlet, Citation2011). REVEL=Columbia River at Revelstoke Dam, CORRA=Kootenay River at Corra Linn Dam, WANET=Pend Oreille River at Waneta Dam, LIBBY=Kootenai (Kootenay) River at Libby Dam, DWORS=N.

The largest reductions in low flows occur west of the Cascade Range in the simulations. Note that unlike the raw VIC flux files discussed above (Table 2), imperial units are used for these products on the study website (cubic feet per second, inches, degrees Fahrenheit). In particular, it is clear that Canada will have not only about 50% of the reservoir storage in the CRB (Hamlet, Citation2003) but also an increasingly dominant portion of the natural water storage as snowpack in the future. 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). hbbd```b``z"I09 D.^`,L,=`v0fI" IA$C(QDrML@a`ig c Future work on the project will likely focus on expanding the number of streamflow sites for which products are available (e.g., inclusion of additional sites in coastal Oregon in the site-specific products) and providing a comprehensive suite of products associated with CMIP5 results (Taylor, Stouffer, & Meehl, Citation2012) associated with IPCC AR5. This approach was partly based on practical limitations on time and computational resources but was also informed by previous experience using the VIC model at finer spatial scales. NWPCC (Northwest Power and Conservation Council). If neither naturalized nor modified flow is available, no bias-adjusted data were provided. The authors would like to acknowledge the contributions of other members of the CBCCSP research team at the UW including Lara Whitely Binder, Pablo Carrasco, Jeffrey Deems, Carrie Lee, Dennis P. Lettenmaier, Tyler Kamstra, Jeremy Littell, Nathan Mantua, Edward Miles, Kristian Mickelson, Philip W. Mote, Erin Rogers, Eric Salath, Amy Snover, and Andrew Wood. Cooper, R. M. (2002). The Columbia Basin Climate Change Scenarios Project (CBCCSP) was conceived as a comprehensive hydrologic database to support climate change planning, impacts assessment, and adaptation in the Pacific Northwest (PNW) by a diverse user community with varying technical capacity over a wide range of spatial scales. Communities across the region and around the world are demonstrating that its possible to adapt, to reduce greenhouse gas emissions, and continue to thrive. 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. Fine-scale calibration of the model to compensate for such errors, although technically feasible, is of questionable utility, because it essentially ensures that the model is getting something closer to the right answer for the wrong reasons, which in turn has the potential to distort the sensitivity of the model to changing future conditions (Bennett, Werner, & Schnorbus, Citation2012). unpublished manuscript). Schnorbus, M. A., Bennett, K. E., Werner, A. T., & Berland, A. J. 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). Southwest wind 5 to 15 mph with gusts to around 25 mph. A 20 percent chance of rain in the afternoon. They found that the vast majority of locations across the Columbia River Basin are expected to experience increases in maximum streamflow magnitudes in the future. The methods are discussed in more detail in these references, but a brief description of the procedure is given here to help orient the reader. Fig. A flight of geese circle over Moses Lake Saturday morning. In this case only modified flows (2000-level modified flows obtained from the BPA (Crook, Citation1993)) were used to train the bias-correction procedure, even if naturalized flows were also available. Post-processing of the primary VIC model output (see Table 2) was carried out to produce a number of specific products discussed in the following sections. Calibration of the VIC model was carried out using an automated calibration tool called MOCOM-UA developed by the Land Surface Hydrology group at the UW, following the approach described by Yapo, Gupta, and Sorooshian (Citation1998). The primary activities and objectives of the RMJOC studies are described in the Executive Summary of the project report (US Department of the Interior, Citation2012): The Bonneville Power Administration (BPA), U.S. Army Corps of Engineers (USACE), and U.S. Bureau of Reclamation (Reclamation) collaborated to adopt climate change and hydrology datasets for their longer-term planning activities in the ColumbiaSnake River Basin (CSRB). Citation2000) were selected as the basis for the study because they provide a) a wide range of plausible outcomes while also reflecting some potential GHG mitigation by the end of the twenty-first century, and b) most of the approximately 20 GCM projections associated with the CMIP3 archived runs from both emission scenarios (Mote & Salath, Citation2010). Text files (six per figure) providing all the ensemble data used to construct each panel in the figure are also provided on the CBCCSP website. The Climate Resilience Program helps communities in the Basin become more climate resilient by supporting large-scale, multi-year, shovel-ready climate mitigation, adaptation, and resilience projects that address sources of climate change or manage the risks of climate change impacts. 7). Exploring a Large Ensemble of Simulations Across a Diversity of Hydroclimates. 3099067 (Citation2010). 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. This is likely because soil moisture is higher in summer west of the Cascade Range and evapotranspiration is mostly energy limited, whereas east of the mountains the late summer soil moisture is already very low in the current climate and increasing evapotranspiration does not result in much additional soil moisture stress. Here, however, we show the same figures in metric units. One of the major climate change impacts already being seen in the Columbia Basin has been the decreases in winter snowpack, the increase in winter precipitation events, and the resulting shifts in flow regime in the Columbia River and its tributaries. The WDOE was also directed to incorporate climate change explicitly in these comprehensive assessment efforts. Blue traces show monthly averages for historical conditions; the pink bands show the range of projected change associated with each scenario and future time period; the red lines show the average of the future ensemble. About 50 of the 80 sites evaluated show monthly NSE scores greater than or equal to approximately 0.7 (good to excellent fit). Broad changes in shallow groundwater (e.g., localized contributions to streamflow from smaller unconfined aquifers), however, are likely well captured by the VIC model based on a strong correlation between VIC-simulated base flows and observations in many basins examined by Wenger et al. Building the Columbia Basin-Boundary Region's Capacity to Adapt to Climate Change. Rain-dominant basins in the United States (e.g., Chehalis River at Grand Mound in Fig. Daily and monthly average streamflow for all projections listed in Table 1 and, where possible, daily and monthly bias-corrected streamflow values. Highs in the lower to mid 40s. Additional details on the approach and methods are available in the CBCCSP study report (Hamlet, Carrasco, et al., Citation2010a). As an integrated priority, the Trust has integrated climate resilience into its strategic priorities by supporting: wildfire risk reduction and job creation through the Columbia Basin Wildfire Resiliency Initiative energy retrofits, repairs and alternative energy generation at community-purpose buildings through the Non-profit Sustainability - Building Support Grants Did you know that with a free Taylor & Francis Online account you can gain access to the following benefits? Friday Mostly sunny. The Columbia Basin-Boundary region is already experiencing a climate thats different from 50 years ago. The Columbia Basin Climate Change Scenarios Project (CBCCSP) was conceived as a comprehensive hydrologic database to support climate change planning, impacts assessment, and adaptation in the Pacific Northwest (PNW) by a diverse user community with varying technical capacity over a wide range of spatial scales. Has spring snowpack declined in the Washington Cascades? As mentioned above, 20062007 was something of a turning point for regional stakeholders considering future actions to prepare for climate change. The CBCCSP database has been a valuable public resource that has dramatically reduced costs in a number of high-visibility studies in the PNW and western United States focused on technical coordination and planning. In 2008, many of the financial and institutional barriers to climate change assessment and adaptation that had been erected over the preceding eight years by the Bush Administration were substantially reduced by the incoming Obama Administration. Water Level Models, Floodplain Wetland Inundation, and System Zones, Using expressed behaviour of coho salmon (Oncorhynchus kisutch) to evaluate the vulnerability of upriver migrants under future hydrological regimes: Management implications and conservation planning. 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. The BCSD runs are transient runs from 1950 to 2098 or 1950 to 2099 (depending on the GCM). The VIC implementations make use of preprocessed soil and vegetation databases for the basin of interest. For the future scenarios, the range of the projections (pink shading) is plotted. Thanks also to Nancy Stephan (BPA), John Fazio and Jim Ruff (NWPCC), Allan Chapman and Ben Kagasniemi (BCME), and Barry Norris (OWRD) for their contributions to the initial study design. During initial model development steps, Elsner et al. Figure 4 shows a flow chart of these post-processing steps. The Assessment was initiated in June 2013 and is expected to completed in December 2015. Additional streamflow sites were routed from the primary VIC data, and water temperature simulations for a number of additional sites were based on temperature projections from the study. Treaty Relating to Cooperative Development of the Water Resources of the Columbia River Basin, United States of AmericaCanada, January 17, 1961September 16, 1964, 15 U.S.T. Nakienovi, N., Alcamo, J., Davis, G., De Vries, B., Fenhann, J., Gaffin, S.,Dadi, Z. 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. As noted above, such errors are commonly encountered at relatively small spatial scales, particularly when meteorological stations are sparse, and often cannot be resolved using conventional hydrologic model calibration strategies. Bias adjustment was also used in preparing the specific reservoir modelling support products discussed below. To produce the bias-adjusted flows, a bias correction procedure using quantile mapping techniques is applied (Elsner et al., Citation2010; Snover et al., Citation2003; Vano et al., Citation2010). Naturalized and modified streamflow data were used to produce bias-corrected streamflow realizations (see below).

The top two panels show the Nash Sutcliffe Efficiency (NSE) (left) and R 2 (right) for the calibration period, while the two lower panels show NSE (left) and R 2 (right) for the validation period. 2013b. 6. A primary motivation for the study was to support planning at geographic scales ranging from relatively small river basins (e.g., planning studies in individual sub-basins, such as the Yakima or Okanagan basins) to main-stem planning studies for the CRB as a whole (e.g., planning studies for the Columbia River hydro system). The PET is shown to increase dramatically over most of the domain (primarily because of warming in the scenarios), whereas AET shows widespread declines east of the Cascade Range. 5. Northeast wind 5 to 10 mph. Because of a general lack of observed naturalized daily time-step flow for most streamflow sites, daily time step calibration using additional parameters such as the infiltration parameter (bi ) in VIC (Liang et al., Citation1994), or routing parameters (such as the unit hydrograph for each cell) were not attempted during the study.

The study employs a state-of-the-art, end-to-end data processing sequence that moves from raw GCM output to a set of final hydrological products that can be accessed by the user community from a web-accessible database. Why is a 1C increase such a big deal? Fig. Incidence of Bactericera cockerelli (Hemiptera: Triozidae) under different pesticide regimes in the lower Columbia basin. (1 April SWE and SWE2PR values were calculated using the CD VIC scenarios.). Thanks to Sean Fleming (Environment Canada) for spearheading this contribution to Atmosphere-Ocean. Regional summaries were prepared by Tohver et al. The calibrated CBCCSP VIC model was modified by WSU by integrating it with a sophisticated crop model (CropSyst; Stckle, Donatelli, & Nelson, Citation2003) that, among other functions, estimates crop water demand. The CBCCSP, in particular, provided access to additional scenarios and downscaling methods that provided a range of hydrologic outcomes associated with uncertainty in the climate projections, which the WACCIA assessments largely did not.
