It drains roughly 260,000 square miles and travels more than 1,240 miles from its headwaters in the Rocky Mountains to its confluence with the Pacific Ocean. Climate Resilience - Columbia Basin Trust These lands are those without any sort of status that provides government protection, such as an indigenous territory, or that have not . Interactive influences of climate change and agriculture on aquatic habitat in a Pacific Northwestern watershed, PROJECTED CLIMATE CHANGES OVER THE MIDWEST AND GREAT LAKES REGION, River Bed Elevation Variability Reflects Sediment Supply, Rather Than Peak Flows, in the Uplands of Washington State, Springs as hydrologic refugia in a changing climate? Climate Change Impacts on the Columbia Basin 10 Left panel: Changes in Q100 for 297 streamflow locations expressed as a ratio of Q100 for the future period to Q100 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. From ecosystems, communities, and infrastructure, to our way of lifeeverything will be affected. 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. Using these resources, other modelling groups can carry out their own investigations of hydrologic impacts using either their own hydrologic model (just using the driving data) or the VIC implementation from the CBCCSP. 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. hL4+ze Multi-Objective Complex Evolution Procedure, developed at the University of Arizona (Yapo et al., A water resources simulation model developed by Labadie (, National Centers for Environmental Prediction, Pacific Climate Impacts Consortium, University of Victoria. All of the meteorological forcing data, except wind speed, are reproduced in the output files produced by the hydrologic model. Glacier outlines are automatically generated from satellite imagery and are provided by, Species and Ecosystems at Risk as identified by the, Current bioclimates and modeled bioclimates for three future climate scenarios in 2080s.

This diagnosis is confirmed by the R 2 values for the same sites, which are generally higher and more consistent with neighbouring values over the entire domain. The largest increases in flooding are in mixed-rain-and-snow basins whose current mid-winter temperatures are within a few degrees of freezing. 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. 2013a. Explore this website to learn more about the changes were expecting, and what we can do about them. Other climate change studies on the Columbia River and its sub-basins followed (Cohen, Miller, Hamlet, & Avis, Citation2000; Elsner et al., Citation2010; Hamlet, Citation2003, Citation2011; Hamlet, Lee, Mickelson, & Elsner, Citation2010b; Lee, Fitzgerald, Hamlet, & Burges, Citation2011; Lee, Hamlet, Fitzgerald, & Burges, Citation2009; NWPCC, Citation2005; Payne, Wood, Hamlet, Palmer, & Lettenmaier, Citation2004; Snover, Hamlet, & Lettenmaier, Citation2003; Vano et al., Citation2010). NWPCC (Northwest Power and Conservation Council). The Columbia Basin Climate Source is your one-stop destination for information about climate change, impacts, and action in this region. A family of greenhouse gas emissions scenarios used in the IPCC effort (Nakienovi et al. This has prompted the National Weather Service to issue a winter weather advisory for the Tri-Cities, Walla Walla, Hermiston, and surrounding areas in effect from 04:00 to 22:00 Sunday. 11). As mentioned in the introduction, WA HB2860, which provided the bulk of the funding for the CBCCSP, also charged WDOE with identifying where US$200 million earmarked for water resources infrastructure improvements should be spent. (Citation2010). Table 1 summarizes the 77 future meteorological forcing datasets that were prepared for the study. The SRES A1B and B1 GHG emissions scenarios (Nakienovi et al. The Columbia Basin-Boundary region is already experiencing a climate thats different from 50 years ago. A 20 percent chance of rain showers in the evening.

In this section we provide an overview of the methods associated with the primary elements of the CBCCSP. 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. Climatic Change 113:499-524. About 50 of the 80 sites evaluated show monthly NSE scores greater than or equal to approximately 0.7 (good to excellent fit). These extended meteorological data have proved particularly useful in supporting ecological studies (e.g., Littell et al., Citation2010).

Columbia Basin Dive Rescue has been serving the community for almost 50 years. Rain dominant basins (DJF temperatures greater than 2C) show moderate increases in flood risk (primarily reflecting increasing storm intensity in the simulations), whereas snowmelt-dominant basins that currently flood in June show relatively little change in flood risk. The strategy for model calibration used in the CBCCSP was to calibrate 11 relatively large sub-basins within the domain (Fig. (1 April SWE and SWE2PR values were calculated using the CD VIC scenarios.). endstream endobj startxref At the other extreme, for those without any hydrologic modelling or post-processing capability the study provides a wide range of hydrologic products that can be used without any expertise in the preceding steps. Columbia River | Location, Length, History, & Facts | Britannica Eleven of the last twelve years (1995 -2006) rank among the 12 warmest years in the instrumental record of global surface temperature (since 1850). 8) and warmer and drier summers (which increase PET) (Fig. Naturalized flow products from specific sites were also used to provide naturalized inflows at model nodes needed to run the USBR MODSIM (Labadie, Citation2007) reservoir model for the Snake River basin. Thursday Sunny. Climate Resilience Program - Columbia Basin Trust 6). (For example, Dworshak and Milner are nested within the larger Ice Harbor sub-basin.). 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). PDF Columbia River Basin Fact Sheet - usbr.gov Other impacts, such as changes in soil moisture dynamics are also apparent in the simulations. 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. Determining surface water availability in Oregon. Oregon Water Resources Department. Gusts up to 20 mph in the morning. 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. 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). Both calibration and validation periods were chosen to test model performance over a wide range of climate and streamflow conditions. 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. The Climate of the Columbia Plateau in Washington State A comprehensive website was to be developed to serve all the data produced by the study, at no cost, to the general public, management professionals agency staff members, scientific researchers, private sector consultants, etc. The city's average temperature is 57 F (14 C). These data were compiled from naturalization studies prepared for the BPA (Crook, Citation1993), WDOE (Flightner, Citation2008), OWRD (Cooper, Citation2002), IDWR, and the USBR. A number of high-visibility studies have made use of the CBCCSP database to date, a few of which are summarized below. Act relating to water resource management in the Columbia river basin, H.R. Click the download link to get the current station data. 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. Open File Report SW 02-002. Snover, A. K., Hamlet, A. F., Lee, S.-Y., Mantua, N. J., Salath, E. P. Jr, Steed, R., & Tohver, I. These products are based solely on the CD and HD projections listed in Table 1. 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. The PET increases over most of the PNW in summer as a result of rising temperatures; however, AET is reduced in all but a few areas of the domain because AET is water limited and summer precipitation decreases in the simulations. hbbd```b``z"I09 D.^`,L,=`v0fI" IA$C(QDrML@a`ig c 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). Blue lines show the average historical values (19162006) (repeated in each panel). Simulations of floods and extreme low flows increase in intensity for most of the river sites included in the study. Atmosphere Ocean 51. Highs in the lower to mid 40s. In most basins with substantial snowpack, elevated soil moisture in winter accompanies warming in the simulations resulting from more infiltration from rain in the fall and winter months (Fig. 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). Climate Change Challenge In The Columbia River Basin: Managing Water What Does Climate Change Mean for Flooding in the Columbia River Basin 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. Since its inception in 1995, CIG has been extensively involved in climate-related research focused on the CRB and its water resources management systems. 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. Isaak DJ et al. Monday: A chance of snow before 4 p.m., then a slight chance of rain and snow. In 2006, The Act relating to Water Resource Management in the Columbia River Basin [hereinafter HB2860] (2006) directed the WDOE to study water resources systems in Washington and identify specific projects in which to invest up to US$200 million provided by the bill to improve water resources infrastructure or management systems. Additional products such as bias-adjusted inflow sequences for specific reservoir operations models are also included. Highs around 80. Key products from the study include detailed summary data for about 300 river sites in the PNW and monthly GIS products for 21 hydrologic variables over the entire study domain. Pink bands show the range of nine or ten HD climate change scenarios for B1 and A1B emissions scenarios for three future time periods. Subsetted from the, Averaged periodic drought condition ranking by basin for 2015-2020 from the, Mapped extent of wildfires from 1950-2020 from, Air quality monitoring stations within the study area. 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. Using the VIC model, Mote, Hamlet, Clark, and Lettenmaier (Citation2005), Mote, Hamlet, and Salath (Citation2008), for example, showed excellent reproduction of observed trends in 1 April SWE over both the PNW as a whole and over the Cascade Range in Oregon and Washington. Starting from these parameter sets, an additional large-scale calibration was performed during the CBCCSP to improve model performance in reproducing historical streamflow. Lows in the lower 50s. What Matters Most: Are Future Stream Temperatures More Sensitive to Changing Air Temperatures, Discharge, or Riparian Vegetation? What Makes The Columbia River Basin Unique and How We Benefit Pink bands show the range of nine or ten HD climate change scenarios for B1 and A1B emissions scenarios for three future time periods. Demand factored into Columbia River Basin's future - WSU Insider Statistics for hydrologic extreme events (as discussed above) are presented in a different format, shown in Fig. Climate Adaptation. 1555. These basins experience dramatic losses of snowpack and substantial changes in seasonal flow timing (Fig. National Weather Service The approach used a refined version of the methods established by Hamlet and Lettenmaier (Citation2005), which created a hybrid historical meteorological dataset based on three primary data resources: a) monthly HCN data in the United States and the similar AHCCD datasets in Canada, b) daily data from the cooperative station network in the United States (co-op stations) and similar data from Environment Canada, and c) a monthly climatology (19712000) for precipitation and daily minimum and maximum temperatures at 30 arc-second resolution produced using the PRISM (Daly, Gibson, Taylor, Johnson, & Pasteris, Citation2002; Daly, Neilson, & Phillips, Citation1994; DiLuzio, Johnson, Daly, Eischeid, & Arnold, Citation2008). 7). Colombia - Climate | Britannica Source: Hi/Low, RealFeel, precip, radar, & everything you need to be ready for the day, commute, and . 2), for which overall errors in meteorological driving data were assumed to be relatively small; then, using these model parameters, to check the results in smaller sub-catchments. Intermediate products are available as well, which can be used by people with GIS capabilities, but with little or no knowledge of climate projections and hydrologic modelling. 1 Map of the selected streamflow locations supported by the CBCCSP. By the end of the twenty-first century, essentially the entire state is classified as rain-dominant for the A1B scenario, and the B1 scenario is only slightly different (Fig. A primary focus of the Assessment is to generate future climate change flow at more than 300 locations across the Columbia River Basin (Basin) and evaluated the potential impact of those flows at specific sub-basins within the Basin. Special thanks to Kurt Unger and Ken Slattery, who were the primary architects of the CBCCSP at WDOE. Mostly cloudy, with a high . 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. Cited by lists all citing articles based on Crossref citations.Articles with the Crossref icon will open in a new tab. Data from the CBCCSP are currently supporting two CIG studies funded by the LCCs and the CSC, including a study of impacts to wetlands in the PNW (funded by the North Pacific LCC and the PNWCSC) and a study assessing climatic and hydrologic extremes and their effects on ecosystems over the western United States (funded by the PNWCSC). 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). 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. Preparing for climatic change: The water, salmon, and forests of the Pacific Northwest. The approach and methods are more fully described in the study report (Hamlet, Carrasco, et al., Citation2010a, Chapter 3) and also by Elsner et al. The highest value of baseflow is Ds max (in millimetres of runoff per time step) for a saturated soil layer; Ws represents the soil moisture threshold below which the baseflow curve is linear; and Ds is the baseflow value (in millimetres) at this breakpoint. Impacts of 21st-century climate change on hydrologic extremes in the Pacific Northwest region of North America. These spatial variations in the change in AET are broadly reflective of the dominant drivers of AET in each case. 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. Zone Area Forecast for Lower Columbia Basin of Washington 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. Results from the study show profound changes in spring snowpack and fundamental shifts from snow to rain-dominant behaviour across most of the domain. Figure 8 shows hydrographs from selected basins with different hydrologic classifications (snowmelt-dominant, mixed-rain-and-snow, and rain-dominant) in the United States and Canada.
