hL4+ze A number of regional partners provided recommendations for streamflow locations and other in-kind support including Jesse Abner (MDNR), Steve Running (University of Montana), Hal Anderson (IDWR) Levi Brekke, Pat McGrane and John Roache (USBR), Carolyn Fitzgerald (Seattle District USACE), Seshu Vaddey and Randy Wortman (Portland District USACE). Gridded datasets provide full spatial coverage (i.e., all grid cells in the model domain) at monthly time scales, of the key hydroclimatic variables listed in Table 2. The CBCCSP was founded on the basis of regional partnerships to support a shared need for climate change scenarios and directly encompassed the transboundary nature of the CRB's management framework by including both US and Canadian interests in an integrated and comprehensive data resource. Explore this website to learn more about the changes were expecting, and what we can do about them. 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. 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. Topographic corrections for precipitation and temperature are carried out by rescaling the data by a fixed factor for each calendar month so that the mean values from 1971 to 2000 match the PRISM climatology for the same period.

Site specific data [Data]. 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. The sweeping statements in the 2007 IPCC AR4 (Solomon et al., Citation2007) regarding the scientific consensus on observed warming (unequivocal) and the direct human role in the alteration of the climate system (90% confidence) made it clear to many management professionals that the waiting game for climate change planning was nearing an end. In other words, dry areas east of the Cascade Range have less base-flow potential to lose with increasing evapotranspiration and loss of summer precipitation because the soil moisture is already at very low levels in late summer. 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.

Inset numbers at the upper left in the future projections are the percentage changes in 1 April SWE averaged over each grid cell in the entire domain. Although results from the WACCIA would arguably have been adequate to support WDOE's adaptation planning, the CBCCSP provided additional foundation support for these efforts, and helped improve confidence in the outcomes of the adaptation strategies identified by better quantifying a range of outcomes. Either naturalized or modified flows (Crook, Citation1993) are used for bias correction of data provided in the site-specific products discussed below, with naturalized data taking precedence if available. 6 Example of a summary plot for extreme high flows (Q20, Q50, Q100, left panels) and extreme low flows (7Q10, right panels) for the Skagit River at Mount Vernon for two emissions scenarios (A1B, B1) and three future time periods (2020s, 2040s, 2080s). Figures and summary tables for long-term average monthly precipitation, monthly average temperature, evapotranspiration, PET4 (Table 2), PET5 (Table 2), total column soil moisture, SWE, combined flow (runoff+baseflow). 7 Left panel: Simulated historical 1 April snow water equivalent (SWE) (upper right) and percentage changes in 1 April SWE for two emissions scenarios and three future time periods extracted from the CD VIC scenarios. In relatively wet and cool areas along the coast and at high elevation in the northern parts of the basin, summer AET is energy limited; therefore, rising temperatures result in increases in AET. People also read lists articles that other readers of this article have read. Most of the fundamental details regarding the VIC implementation used in this study are covered by Elsner et al. 11 Changes in 7Q10 for 297 river locations expressed as a ratio of 7Q10 for the future period to 7Q10 for the historical period based on the average of the nine or ten HD scenarios for the B1 and A1B emissions scenarios for three future time periods, by permission of I. Tohver, A.F. Lee. Rain-dominant basins in the United States (e.g., Chehalis River at Grand Mound in Fig. Northeast wind 5 to 10 mph. The Assessment was initiated in June 2013 and is expected to completed in December 2015. By late 21st century, annual precipitation increases by 5% (8%), with an 8% (14%) winter increase and a 4% (10%) summer decrease, but because . For the BCSD runs (for which the ability to capture key elements of the region's climate variability is arguably even more important to the outcomes) the projections based on the seven highest ranked GCMs (Table 1) were selected for each emissions scenario. Fig. The CIG (http://cses.washington.edu/cig/; see the Table of Acronyms in the Appendix) is an interdisciplinary research group at the UW focused on climate-related research in five major sectors: atmospheric sciences, hydrology and water resources, aquatic ecosystems, forests, and coasts. Hydrology and water resources research at CIG was particularly focused on the use of experimental climate and hydrologic forecasts for the CRB (Hamlet & Lettenmaier, Citation1999a, Citation2000; Lettenmaier & Hamlet, Citation2003; Leung, Hamlet, Lettenmaier, & Kumar, Citation1999) in the context of decision support for various water management applications (Hamlet, Huppert, & Lettenmaier, Citation2002; Lee, Hamlet, Fitzgerald, & Burges, Citation2011; Voisin et al., Citation2006). Three base flow parameters (Ds max, Ds, Ws) associated with the non-linear baseflow curve from the third soil layer (Liang et al., Citation1994) were used to calibrate the model. hbbd```b``z"I09 D.^`,L,=`v0fI" IA$C(QDrML@a`ig c Read on for information on our current project. Impacts assessments from the WACCIA played a central role in these planning activities, but updated and extended data from the CBCCSP also materially supported these efforts. 8). The study also used the ColSim reservoir operations model (Hamlet & Lettenmaier, Citation1999b) to estimate water deliveries to the Columbia Basin Project (the primary irrigation project supplied by water from Grand Coulee Dam) under future climate scenarios using streamflows generated by the integrated VIC/CropSyst model. Dave Rodenhuis, Markus Schnorbus, Arelia Werner, and Katrina Bennett at PCIC at the University of Victoria, British Columbia, also provided in-kind support and funding for collaborative research which contributed materially to this project. The VIC model (version 4.0.7) was implemented at 1/16 degree resolution, with three active soil layers and up to five elevation bands with an approximate spacing of 500m. The model was run in water balance mode with a snow model time step of 1h and a water balance time step of 24h. The model was coupled to a simple daily-time-step routing model (Lohmann, Raschke, Nijssen, & Lettenmaier, Citation1998), which was used to produce daily flow estimates at each of the approximately 300 streamflow locations included in the study. This advance through the native forest has been driven, primarily, by cattle ranching. Since 2014, the RDI has engaged in applied research related to community climate adaptation. Crook, A. G. (1993). 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. The Columbia Basin Climate Source is your one-stop destination for information about climate change, impacts, and action in this region. The USFS and USFWS studies have supported a number of high-visibility ecosystem studies, including assessment of the impacts of changing snowpack on wolverine populations (McKelvey et al., Citation2011) and subsequent proposed ESA listing of wolverine populations, and comprehensive assessment of climate change impacts to trout species over the west (Wenger et al., Citation2011). 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. A low pressure system slowly moving offshore is forecast to spin moisture into the Columbia Basin Sunday as it meanders closer to the Southern Oregon Coast. The CBCCSP also included fine-scale hydrologic modelling using DHSVM (Wigmosta et al., Citation1994, Citation2002) in four pilot watersheds in the PNW. 7). A family of greenhouse gas emissions scenarios used in the IPCC effort (Nakienovi et al. Tonight Mostly cloudy. 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. 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. 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). Climate Adaptation. Gusts up to 20 mph in the morning. 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). %%EOF An Overview of the Columbia Basin Climat . : From Icefield to Estuary: The Columbia Basin / Du champ de glace l'estuaire : Le bassin du Columbia, 6 Use of products and information by stakeholders, water professionals, and researchers, https://doi.org/10.1080/07055900.2013.819555, http://cses.washington.edu/cig/res/ia/waccia.shtml, doi:http://dx.doi.org/10.1175/JCLI-D-11-00417.1, http://warm.atmos.washington.edu/2860/products/sites/, doi:10.1175/1520-0450(1994)033<0140:ASTMFM>2.0.CO;2, doi:10.1175/1520-0477(1998)079<2715:IMOET>2.0.CO;2, http://warm.atmos.washington.edu/2860/report/, doi:10.1061/(ASCE)0733-9496(2002)128:2(91), doi:10.1061/(ASCE)0733-9496(1999)125:6(333), doi:10.1175/1520-0477(1996)077<0437:TNYRP>2.0.CO;2, doi:10.1061/(ASCE)0733-9496(2009)135:6(440), doi:10.1175/1520-0477(1999)080<2313:SOTEHS>2.0.CO;2, http://cses.washington.edu/picea/USFS/pub/Littell_etal_2010/Littell_etal._2011_Regional_Climatic_And_Hydrologic_Change_USFS_USFWS_JVA_17Apr11.pdf, doi:10.1175/1520-0477(1997)078<1069:APICOW>2.0.CO;2, http://www.nwcouncil.org/energy/powerplan/5/, doi:10.1175/1520-0477(1997)078<2771:TDOENO>2.0.CO;2, http://www.usbr.gov/newsroom/newsrelease/detail.cfm?RecordID=39123, http://www.usbr.gov/pn/programs/climatechange/reports/index.html, http://www.fws.gov/landscape-conservation/lcc.html, http://www.ecy.wa.gov/biblio/1112011.html, Medicine, Dentistry, Nursing & Allied Health, Simulated daily evapotranspiration from all sources, actual evaporation from all sources (canopy evaporation, evaporation from bare soil, transpiration, and snow sublimation), natural vegetation, no water limit, but no vegetation stomatal resistance, Extreme 7-day low flow value with a 10-year recurrence interval. Determining surface water availability in Oregon. The Columbia Basin Climate Source is your one-stop destination for information about climate change, impacts, and action in this region. 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. Red dots indicate sites that are essentially unimpaired by human use or for which there is estimated modified* or naturalized flow. Climatic Change 113:499-524. 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 city's average temperature is 57 F (14 C). The results were only slightly better than those achieved in the large-scale calibration. Although results could potentially vary in different areas of the model domain, these results support the hypothesis that only modest improvements in validation statistics would result from individual calibration of additional streamflow sites within each sub-basin. These products are based solely on the HD projections listed in Table 1. Click the download link to get the current station data. Potential evapotranspiration increases over most of the PNW in summer because of rising temperatures; however, actual evapotranspiration is reduced in all but a few areas of the domain because evapotranspiration is mostly water limited in summer, and summer precipitation decreases in the simulations.
