What Does Climate Change Mean for Flooding in the Columbia River Basin 0 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. Determining surface water availability in Oregon. The largest increases in flooding are in mixed-rain-and-snow basins whose current mid-winter temperatures are within a few degrees of freezing. A number of high-visibility studies have made use of the CBCCSP database to date, a few of which are summarized below. Typical month of historical flooding events is shown by the colour of the dots in the scatter plot (legend inset in the upper right corner), by permission of I. Tohver, A.F. 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 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. Sites without modified or natural flow estimates are shown in yellow. USFWS (US Fish & Wildlife Service). These data were compiled from naturalization studies prepared for the BPA (Crook, Citation1993), WDOE (Flightner, Citation2008), OWRD (Cooper, Citation2002), IDWR, and the USBR. Act relating to water resource management in the Columbia river basin, H.R. 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). 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. hL4+ze It is important to acknowledge that opinions differ on the utility or even possibility of improving ensembles of future projections based on the ability to simulate the past climate (e.g., Gleckler, Taylor, & Doutriaux, Citation2008). As mentioned above, 20062007 was something of a turning point for regional stakeholders considering future actions to prepare for climate change. 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. However, some areas west of the Cascade Range and in the northern Rockies show increasing AET. Thanks to Shrad Shukla, at the UW for 1/16 degree VIC model calibration over the Yakima basin. Demand factored into Columbia River Basin's future - WSU Insider Building the Columbia Basin-Boundary Region's Capacity to Adapt to Climate Change. 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. 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). Figure 1. 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. 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. 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. 1 Map of the selected streamflow locations supported by the CBCCSP. Naturalized or modified flow data were available at a number of locations in the PNW. Weather for Queens Cup Basin, British Columbia, Canada Hamlet, A. F., Carrasco, P., Deems, J., Elsner, M. M., Kamstra, T., Lee, C., Lee, S-Y, Mauger, G., Salathe, E. P., Tohver, I., & Binder, L. W. (2010a). Changes in snowpack are a key driver of hydrologic impacts in the PNW (Elsner et al., Citation2010; Hamlet & Lettenmaier, Citation1999b). Blue dots represent the historical values; the red dots show the range of values from the HD ensemble (10 or 9 values); black dashes show the mean of the HD ensemble, and the orange dots show the single value calculated for the CD projections. Incidence of Bactericera cockerelli (Hemiptera: Triozidae) under different pesticide regimes in the lower Columbia basin. Observations around the world demonstrate that the global atmosphere has been warming rapidly since the 1970s, with temperatures up an average of 1.7 degrees Fahrenheit in that time and expected to increase between 1 and 4 degrees by the 2030s, Pytlak said. Daily and monthly average streamflow for all projections listed in Table 1 and, where possible, daily and monthly bias-corrected streamflow values. 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). 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. Corresponding shifts in the seasonal timing of streamflow are also relatively small in the Canadian CRB until late in the twenty-first century.

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. 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. Warming of the global climate is unequivocal. The CBCCSP database has been a valuable resource which has dramatically reduced the cost of a number of high-visibility planning studies in the PNW, including the RMJOC water resources planning studies conducted by the BPA, USBR, and USACE, WSU integrated crop modelling and irrigation water demand studies under HB2860, the WA Integrated Climate Change Response Strategy, and west-wide extensions of the CBCCSP supported by the USFS and USFWS. 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. These results point to extensive, landscape-scale transformations in hydrologic behaviour associated with climate change. 2013b. 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. 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. 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. Why is a 1C increase such a big deal? 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. The DOI via the USFWS has recently established a set of LCCs across the United States (USFWS, Citation2013) and has generated additional funding to support a group of regional CSCs, one of which was recently established in the PNW (PNWCSC), combining the efforts of about 15 PNW research universities, jointly led by the USGS, Oregon State University, the UW, and the University of Idaho. 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. Dark red lines show the average of the climate change ensemble. Because both these effects increase flood risk in the simulations, the effects are unusually large in these basins (Fig. For the future scenarios, the range of the projections (pink shading) is plotted. Fig. 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. This is a good example of the use of the study data to support relatively fine-scale planning needs. Tonight Mostly cloudy. YAKIMA Lower Columbia returned to the diamond on Friday with a double-header split against Yakima Valley. 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. The magnitude of flooding the term used to describe flooding severity is expected to increase throughout the basin, which includes the Columbia, Willamette and Snake rivers . Clima em Guarant do Norte, Mato Grosso - weather.com 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 . 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. 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. The Hot and the Cold of It Summer comes on strong. This web site provides streamflow information for the Columbia River and coastal drainages in Washington and Oregon State for the 21st century based on a large number of climate scenarios and model experiments. How essential is hydrologic model calibration to seasonal streamflow forecasting? 3. IPCC Special Report on Emissions Scenarios (Nakienovi et al. 7-Day Zone Forecast for Upper Columbia Basin (Text-Only) For each streamflow location (and its associated contributing basin area), a set of identical products is available on the study web site (CIG, Citation2013b). Reductions in spring snowpack and summer streamflow, for example, are relatively modest in the Canadian portions of the basin because of cold winter temperatures that delay warming-related impacts to seasonal snowpack (Elsner et al., Citation2010). Even with substantial cuts to greenhouse gas emissions, scientists expect our climate to continue changing over the coming decades. The Columbia Basin-Boundary region is already experiencing a climate thats different from 50 years ago. Hydrologic sensitivity of global rivers to climate change. Because of space limitations, we will not be able to cover these alternative modelling efforts in this paper. After fitting three-parameter generalized extreme value probability distributions to the annual peak flow data, the daily 20-, 50-, and 100-year floods (under natural flow conditions) are estimated for both historical and future periods. 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). 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. 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. 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. Basin topographic map and smoothed basin boundary at 1/16 degree resolution. Fig. The Columbia Basin Climate Source is your one-stop destination for information about climate change, impacts, and action in this region. One of the first major efforts of CIG in this area was focused on the preparation of a detailed and comprehensive regional assessment report for the PNW for the 1999 National Assessment of the Impacts of Climate Variability and Change in the United States (ultimately published as Mote et al., Citation2003). 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. Columbia Basin Care is the region's only independent nonprofit skilled nursing facility for long-term care and short-term rehabilitation. 9. 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. Among its most useful features is the predominantly physical basis of the model, which largely avoids concerns about parameter stationarity in a changing climate. 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). Ten GCM projections for the A1B scenario and nine projections for the B1 scenario (Table 1) were selected based on a ranking of the GCMs reflecting the combined ability of each GCM to reproduce key features of PNW climate variability, including the seasonal cycle of precipitation, observed trends in temperature in the late twentieth century, bias in reproducing historical temperature and precipitation, and ability to capture key features of observed climate variability (spatial patterns of temperature, pressure, and precipitation) over the North Pacific (Mote & Salath, Citation2010).
