Statistics for hydrologic extreme events (as discussed above) are presented in a different format, shown in Fig. 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. The objective function for the optimization process in this case was: where Q is the monthly streamflow; NSE(Q) is the NSE (monthly flow), which varies between [inf, 1] and typically between [0,1]; NSE(log(Q+1)) is the NSE (monthly flow), which varies between [inf, 1] (this metric places less emphasis on high flow errors in calculating NSE); Vol_Err(Q) is the annual volume error (in 1000 acre feet); R 2(Q)=R 2 (squared correlation coefficient between simulated and observed Q), which varies between [0,1]; Peak_Diff(Q) is the mean hydrograph peak differencethe absolute value varies for different sites; RMSE(Q) is the root mean square error, whose absolute value varies for different sites; and NumSC(Q) is the number of sign changes in the errors (this metric penalizes simulations with too much month-to-month variability in comparison with observations). 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. 8).

Gusts up to 20 mph in the morning. A 20 percent chance of rain in the afternoon. 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 model shows reasonably good calibration statistics for the majority of the sites, and the calibration is robust (showing equally good or better statistics in the validation period when compared with the calibration period). Increasing low flow risks (declining 7Q10 values) are widespread across the domain as a result of the combined effects of declining snowpack (which tends to result in earlier streamflow recession and lower flows in late summer, see Fig. From ecosystems, communities, and infrastructure, to our way of lifeeverything will be affected. As a result the largest changes in snowpack are apparent in the simulations for relatively warm coastal mountain ranges, such as the Cascade Range, and at moderate elevation in the Rockies, where snowpack is most sensitive to changes in temperature of a few degrees Celsius. Weather for Monday, Feb. 27. 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. 0 These include the full meteorological forcings for the model (variables 18), a suite of water balance variables simulated by the model (variables 916), and five different PET metrics (variables 1721) (Elsner et al., Citation2010). A number of sub-basins are nested within each other, as shown in the right panel along with their relative sizes. Nakienovi, N., Alcamo, J., Davis, G., De Vries, B., Fenhann, J., Gaffin, S.,Dadi, Z. We should note that glaciers and deep groundwater (e.g., contributions to streamflow from large confined aquifers) are not simulated by the VIC model, and impacts in areas profoundly influenced by these hydrologic features may not be well characterized in the simulations (Wenger et al., 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. The strategy for model calibration used in the CBCCSP was to calibrate 11 relatively large sub-basins within the domain (Fig. Table 1 summarizes the 77 future meteorological forcing datasets that were prepared for the study. It was also well understood by practitioners at CIG that aquatic and terrestrial ecosystem researchers, managers, and stakeholders needed a similar, but more comprehensive, data resource to support long-term planning and the development of climate change adaptation strategies at the landscape scale. Special thanks to Kurt Unger and Ken Slattery, who were the primary architects of the CBCCSP at WDOE. 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). 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). In this section we provide an overview of the methods associated with the primary elements of the CBCCSP. 2860, 59th Legislature (WA 2006). Agencies at the state and local levels were similarly engaged, two notable examples in the PNW being King County, Washington (Casola et al., Citation2005), and the WDOE, which manages (among many other water-related issues) the state's water resources and water quality permitting programs. An overview of the Columbia Basin Climate Change Scenarios Project: Approach, methods, and summary of key results. Columbia Basin Dive Rescue has been serving the community for almost 50 years. The CBCCSP (and extensions over the west) has greatly reduced the costs of these types of studies by supplying (at essentially no cost) a wide range of high-quality hydrologic scenarios as a foundation for further work. By late 21st century, annual precipitation increases by 5% (8%), with an 8% (14%) winter increase and a 4% (10%) summer decrease, but because . (Citation2010). Crook, A. G. (1993). 7-Day Zone Forecast for Upper Columbia Basin (Text-Only) Flooding in the Columbia River basin expected to increase under climate Over the last several years, the USFS and USFWS have engaged with the CIG to produce a set of initial climate change hydrologic scenarios over much of the west using a common methodology intended to support landscape-scale assessment of climate change impacts (Littell et al., Citation2011). %PDF-1.6 % Naturalized streamflow data were used exclusively in the CBCCSP to calibrate the hydrologic model. Fig. 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. Figure 10 shows a map of Q100 ratios (future Q100 to historical Q100) for 297 river locations and a scatterplot of the Q100 ratio as a function of winter temperature regime in each basin. The CBCCSP also provided a complete and well-tested data processing sequence for post-processing and summarizing the hydrologic data to provide figures and analysis efficiently. 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. Nestled in the sunny climate of The Dalles, Oregon just 1.5 hours east of Portland Columbia Basin Care offers around-the-clock medical care, private and semi-private rooms, fresh and nutritious . The CBCCSP provided climate change projections of meteorological drivers and a calibrated VIC implementation in support of the study. Among its most useful features is the predominantly physical basis of the model, which largely avoids concerns about parameter stationarity in a changing climate. This is a good example of the use of the study data to support relatively fine-scale planning needs. 2012.

Open File Report SW 02-002. 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. 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. completed or are ongoing in the Columbia River Basin. Detailed forecast for Lower Columbia Basin of Washington Rest Of Today Partly sunny. Climate Resilience Program - Columbia Basin Trust 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. 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. Temperature and precipitation vary greatly with elevation, but in the central basin January average daily temperatures are between about 25 and 30 F (4 and 1 C), and July averages are mostly between 70 and 75 F (21 and 24 C). Both floods (Q100) and extreme 7-day low flows (7Q10) increase in intensity for most of the river sites simulated.

Even with substantial cuts to greenhouse gas emissions, scientists expect our climate to continue changing over the coming decades. Climatic Change 113:499-524. 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 magnitude of hydrologic extremes such as Q100 and 7Q10 are expected to shift markedly in some basins in response to cool season warming, increasing cool season precipitation, and warmer, drier summers. These approaches are also useful for avoiding biases in the streamflow simulations that result from systematic errors in gridded precipitation or temperature data. Thanks to Shrad Shukla, at the UW for 1/16 degree VIC model calibration over the Yakima basin. This advance through the native forest has been driven, primarily, by cattle ranching. 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. Three VIC model calibration parameters described above were varied in the optimization process, and six error metrics were used to define the objective function: squared correlation coefficient (R 2), NSE, the NSE of log-transformed data, annual volume error, mean hydrograph peak difference, RMSE, and number of sign changes in the simulated streamflow errors. The summary figures for water balance variables at each site have the same format, two examples of which are shown in Fig. Climate Resilience - Columbia Basin Trust Climate Change Impacts on Columbia River Basin Fish and Wildlife Similarly, three different downscaling approaches were used in the study, each with its own advantages and limitations in the context of different natural resources management applications (Hamlet et al., 2010a). The CBCCSP was designed from the outset to support users with a very wide range of technical sophistication and capacity. Why is a 1C increase such a big deal? Daily and monthly average streamflow for all projections listed in Table 1 and, where possible, daily and monthly bias-corrected streamflow values.

Weather for Monday, Feb. 27 | Columbia Basin Herald 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).. Model calibration and validation used a split sample approach in which calibration was performed for each of the 11 primary watersheds over a 15-year period (typically water years 19751989) and model validation was performed over a separate 15-year period (typically water years 19601974). 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. These products are based solely on the CD and HD projections listed in Table 1. Columbia River Basin Basin Overview . We used 50 parameter sets to define the initial optimization parameter space, of which the 25 best parameter sets advance in each evolution of the optimization. .. slide 2 of 5. 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. However, some areas west of the Cascade Range and in the northern Rockies show increasing AET. These data are summarized in figures and tables prepared for each streamflow site discussed in Section 4.
