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. Associated shifts in streamflow timing from spring and summer to winter are also evident in basins with significant snow accumulation in winter (for the current climate). Nakienovi, N., Alcamo, J., Davis, G., De Vries, B., Fenhann, J., Gaffin, S.,Dadi, Z. 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.

These basins experience dramatic losses of snowpack and substantial changes in seasonal flow timing (Fig. The largest changes in flood risk are simulated in mixed-rain-and-snow basins. 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. Casola, J. H., Kay, J. E., Snover, A. K., Norheim, R. A., Binder, L. C. W., & the Climate Impacts Group. As mentioned above, 20062007 was something of a turning point for regional stakeholders considering future actions to prepare for climate change. Application Process How to Apply Sign-up for Program Updates Preparing for climatic change: The water, salmon, and forests of the Pacific Northwest. It reaches a thickness estimated at 16,000 feet in places. These products are based solely on the HD projections listed in Table 1. Snowmelt-dominant basins in the United States, which are somewhat warmer and do not experience as much precipitation change in the scenarios, show increases in winter flow, earlier and reduced peak flow in spring, followed by an earlier streamflow recession and lower flows in late summer (e.g., Columbia River at The Dalles in Fig. 2013a. 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. The scope of work for the project called for hydrologic modellers at CIG to produce the following results: A suite of up-to-date hydrologic projections for the entire CRB (including portions of the basin in Canada) based on the CMIP3/AR4 (Meehl et al., Citation2007) GCM projections. (unpublished manuscript). Lows in the lower to mid 30s. 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. The MOCOM-UA tool uses an objective function (defined by the user) and a shuffle complex evolution procedure to optimize model calibration parameters to create a set of Pareto (equally) optimal calibration parameters. For example, to support academic or agency researchers with their own hydrologic modelling capability, the study provides projections of meteorological drivers such as temperature, precipitation, solar radiation, and humidity and a calibrated VIC hydrologic model implementation. Confirming the sensitivity to warming demonstrated in earlier studies, the CBCCSP results show widespread reductions in the 1 April snowpack, and systematic reductions in the long-term average SWE2PR, a measure of the importance of snow in the hydrologic cycle (Fig. Forest ecosystems, disturbance, and climatic change in Washington State, USA, Regional scale hydrology: I.

The Water Hub contains numerical and spatial data, reports, photos and other types of information about streams, lakes, wetlands, groundwater, snow, glaciers and climate in the Columbia Basin both historical and current. Contact Carri Hessman Program Manager (208) 378-5106 chessman@usbr.gov Bureau of Reclamation (For example, Dworshak and Milner are nested within the larger Ice Harbor sub-basin.). 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). A set of simpler, lumped-storage reservoir operations models was used to quantify impacts in a number of smaller water supply systems. These data are summarized in figures and tables prepared for each streamflow site discussed in Section 4. 12 Changes in monthly mean total column soil moisture (OctoberSeptember) for three representative river sites in the PNW: Kootenay River at Corra Linn Dam (left), Columbia River at The Dalles, Oregon (centre), and Yakima River at Parker (right). 8).

Lows in the upper 30s to lower 40s. Those who lack their own hydrologic model, but wish to make additional runs themselves, can obtain the calibrated VIC model implementation. Gridded databases providing full GIS coverage of important hydrometeorological variables in support of a wide range of research applications, including ecosystem research. Has spring snowpack declined in the Washington Cascades? 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. 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. 5 Examples of summary plots for monthly snow water equivalent (SWE) (mm) (averaged over the upstream basin area) and raw streamflow not adjusted for bias (cubic metres per second) for the Skagit River at Mount Vernon. Daily and monthly streamflow for each streamflow site are provided in two formats: a) raw VIC simulations, and b) bias-adjusted simulations. The CBCCSP was developed to address these diverse needs. 12). What Matters Most: Are Future Stream Temperatures More Sensitive to Changing Air Temperatures, Discharge, or Riparian Vegetation? Source: NOAA Fisheries. Changes in PET (PET3, see Table 2) and AET (see Table 2) are shown in Fig. In addition to creating these datasets, the RMJOC agencies worked together to adopt a set of methods for incorporating these data into those longer-term planning activities. Previso do tempo local de hora em hora, condies climticas, precipitao, ponto de condensao, umidade, vento no Weather.com e The Weather Channel For climate change studies in the western United States where snow is an important element of the hydrologic cycle, the model's use of a sophisticated energy-balance snow model, which incorporates important effects on snow accumulation and melt associated with vegetation canopy (Andreadis, Storck, & Lettenmaier, Citation2009) has been a notable advantage. The strategy for model calibration used in the CBCCSP was to calibrate 11 relatively large sub-basins within the domain (Fig. Pink bands show the range of nine or ten HD climate change scenarios for B1 and A1B emissions scenarios for three future time periods. The VIC implementations make use of preprocessed soil and vegetation databases for the basin of interest. completed or are ongoing in the Columbia River Basin. Crook, A. G. (1993). Funding was received by WSU to carry out research quantifying crop water demand, water resources system performance, and economic impacts under current climate conditions and a range of future climate scenarios. Fig. 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. Les rsultats de ltude montrent de profonds changements dans l'accumulation de neige au printemps et des dplacements radicaux de neige ou pluie et neige mles vers principalement pluie dans presque tout le domaine. Building the Columbia Basin-Boundary Region's Capacity to Adapt to Climate Change. Many river locations that were submitted for consideration were at gauging locations supported by the USGS and ECAN, or at locations associated with important water resources monitoring needs (e.g., checkpoints for flood control, water supply, or environmental flows) or infrastructure (e.g., dams and diversion points). 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.

As noted above, the study also supports planning efforts over a wide range of geographic scales. Simulated widespread increases in soil moisture recharge in fall and winter in areas with significant snow accumulation in winter (for the current climate) support hypotheses of increased landslide risk and sediment transport in winter in the future. Recommended articles lists articles that we recommend and is powered by our AI driven recommendation engine. However, our goal in this case was not to reduce the range of uncertainty by selecting a smaller group of GCMs. The Columbia Basin Climate Source is your one-stop destination for information about climate change, impacts, and action in this region. 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? Other impacts, such as changes in soil moisture dynamics are also apparent in the simulations. The NSE scores for about 20 sites are marginal (between 0.3 and 0.7). Thus, stakeholders can select different products, using different downscaling approaches that are appropriate to their needs. 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. The BCSD runs are transient runs from 1950 to 2098 or 1950 to 2099 (depending on the GCM). During the study (and afterwards), some stakeholders expressed interest in including less optimistic emissions scenarios (such as SRES A1FI), in order to better understand the implications of a potential worst case scenario. Saturday: Mostly cloudy with a 20 percent chance of rain. Weather for Monday, Feb. 27. People also read lists articles that other readers of this article have read. In this section we provide an overview of the methods associated with the primary elements of the CBCCSP. Depending on their needs and/or level of technical sophistication, users can tap into the study databases at a number of different levels. 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). If neither naturalized nor modified flow is available, no bias-adjusted data were provided. An understanding of the basin's transboundary nature has also informed CIG's hydrologic modelling studies, which have consistently provided complete coverage of the Canadian and US portions of the basin. 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). 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. These techniques remove systematic biases in the simulations of routed streamflow to produce products that closely match the long-term statistics of a natural or modified flow dataset for a particular site. hbbd```b``z"I09 D.^`,L,=`v0fI" IA$C(QDrML@a`ig c Naturalized streamflow data were used exclusively in the CBCCSP to calibrate the hydrologic model. Lee. Monday: A chance of snow before 4 p.m., then a slight chance of rain and snow. 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. Flooding in these basins is sensitive to both warming (which raises snow lines and effectively enlarges the contributing basin area during most flood events) and increasing winter precipitation. Registered in England & Wales No. The data is accessible for decision makers, researchers, students, professionals and the public. Click the download link to get the current station data. How essential is hydrologic model calibration to seasonal streamflow forecasting? Associated shifts in streamflow timing from spring and summer to winter are also evident in basins that currently have significant snow accumulation in winter, whereas rain-dominant basins show minimal shifts in streamflow timing. (2000). Les simulations dcoulements de crue et dtiage augmentent en intensit pour la plupart des sites fluviaux compris dans cette tude. This was coordinated through the River Management Joint Operating Committee (RMJOC), a sub-committee of the Joint Operating Committee which was established through direct funding Memorandum of Agreements between BPA, Reclamation, and the USACE. 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. 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. This advance through the native forest has been driven, primarily, by cattle ranching. 3 Summary map of 80 streamflow locations (out of a total of 297) for which error statistics between simulated and naturalized flows were computed. Right panel: Same data shown as a scatter plot of the average ratio of Q100 for the 2040s A1B scenarios to Q100 for the historical period versus historical basin-average mid-winter (DJF) temperature in each case. 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).. 'High Uncertainty' is indicated when Mahalanobis Distance is >1. Des dplacements correspondants des caractristiques dcoulement fluvial du printemps et de lt vers l'hiver sont galement vidents dans les bassins o l'accumulation de neige est importante en hiver (sous le climat actuel). These approaches were further developed and refined during the WACCIA in 2009 (Miles, Elsner, Littell, Binder, & Lettenmaier, Citation2010), which included assessments of aquatic and forest ecosystem impacts (Littell et al., Citation2010; Mantua, Tohver, & Hamlet, Citation2010). 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 CBCCSP also included fine-scale hydrologic modelling using DHSVM (Wigmosta et al., Citation1994, Citation2002) in four pilot watersheds in the PNW. (Citation2010) over the entire PNW (Tohver et al. The Assessment was initiated in June 2013 and is expected to completed in December 2015. 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. The macroscale hydrologic model used in the CBCCSP is the VIC model (Cherkauer & Lettenmaier, Citation2003; Liang, Lettenmaier, Wood, & Burges, Citation1994) implemented at 1/16 degree resolution. 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. Northeast wind 5 to 10 mph. 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. In other words, although at these sites the model results do not match the observations in the absolute sense (large bias), the relative changes follow the observed variations quite well (high R 2). Fig. 2013b. Act relating to state agency climate leadership, S. 5560, 61st Legislature (WA 2009). All of the meteorological forcing data, except wind speed, are reproduced in the output files produced by the hydrologic model. Results from the study show profound changes in spring snowpack and fundamental shifts from snow to rain-dominant behaviour across most of the domain. 9 Left panel: Historical estimates of summer (JJA) potential evapotranspiration (PET) (based on PET3, see Table 2) (upper right) compared with percentage changes in PET for two emissions scenarios and three future time periods from the CD scenarios. 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. To minimize this data processing artifact, boundaries between months were smoothed while keeping the sum of daily streamflows equal to the original monthly values in the final product. A number of sub-basins are nested within each other, as shown in the right panel along with their relative sizes. Fig. Dark red lines show the average of the climate change ensemble. 95 0 obj <> endobj Because both these effects increase flood risk in the simulations, the effects are unusually large in these basins (Fig. The summary figures for water balance variables at each site have the same format, two examples of which are shown in Fig. The largest increases in flooding are in mixed-rain-and-snow basins whose mid-winter temperatures are presently within a few degrees of freezing. 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). (Citation2010). Thanks to Sean Fleming (Environment Canada) for spearheading this contribution to Atmosphere-Ocean. are estimated by the VIC hydrologic model (discussed below) using empirical methods described by Kimball, Running and Nemani (Citation1997) and Thornton and Running (Citation1999). Nous avons implment une rsolution latitudelongitude calibre 1/16 de degr dans le modle capacit d'infiltration variable (VIC) et avons appliqu dans le modle bassin du fleuve Columbia pour produire des simulations historiques et 77 projections hydrologiques futures correspondant trois mthodes de rduction dchelle statistique et trois priodes futures (les dcennies 2020, 2040 et 2080). 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). 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. These results point to extensive, landscape-scale transformations in hydrologic behaviour associated with climate change. 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.
