A key design element of the CBCCSP from the outset of the project was to produce a well-organized and well-documented end-to-end (i.e., GCM to hydrologic products) data processing sequence and a web-accessible data archive that would greatly reduce the cost of producing updates in response to each subsequent CMIP/IPCC cycle. Highs in the lower 80s. Bias-corrected streamflow values are useful in water planning studies, especially for providing inputs to reservoir operations models that are calibrated on a particular naturalized or modified flow dataset (e.g., Hamlet, Lee, et al., Citation2010b; NWPCC, Citation2005; Vano et al., Citation2010).

Impacts of 21st-century climate change on hydrologic extremes in the Pacific Northwest region of North America. 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. Wind speed data are based on interpolated NCEP reanalysis data (Kalnay et al., Citation1996) using methods described by Elsner et al. 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. 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. The Assessment will result in a better understanding the potential impacts of climate change on the eight components identified in SECURE in the Columbia River Basin. Current weather in Queens Cup Basin and forecast for today, tomorrow, and next 14 days 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. A flight of geese circle over Moses Lake Saturday morning. As mentioned above, 20062007 was something of a turning point for regional stakeholders considering future actions to prepare for climate change. One of the fundamental difficulties with this task was that there was not, at the time, an available database of hydrologic projections that could support such planning, and regulatory agencies such as WDOE did not have the capacity or expertise to produce these resources themselves. 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. The most sensitive basins are mixed-rain-and-snow basins. A subsequent study in the Skagit River basin (Lee and Hamlet, unpublished manuscript) has demonstrated that substantial improvements in the simulation of high flow extremes can be achieved by calibrating the routing model, but it is not yet clear whether these conclusions can be generalized to other areas of the domain. Basin topographic map and smoothed basin boundary at 1/16 degree resolution. 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. 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. Northeast wind 5 to 10 mph. Explore the basics of climate science arrow . The results were only slightly better than those achieved in the large-scale calibration. Although not as extreme as A1FI, the high-end A2 scenario was archived by most GCMs and could have been used in the CBCCSP in place of the A1B scenario. 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.

These basins experience dramatic losses of snowpack and substantial changes in seasonal flow timing (Fig. 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. 5; Yakima River at Parker in Fig. Southwest wind 5 to 15 mph with gusts to around 25 mph. 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. Hydrologic climate change scenarios for the Pacific Northwest Columbia River basin and coastal drainages. 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). Those who lack their own hydrologic model, but wish to make additional runs themselves, can obtain the calibrated VIC model implementation. 7). 5 Howick Place | London | SW1P 1WG.

An overview of the Columbia Basin Climate Change Scenarios Project: Approach, methods, and summary of key results. Thursday Night Partly cloudy. 2013b. are estimated by the VIC hydrologic model (discussed below) using empirical methods described by Kimball, Running and Nemani (Citation1997) and Thornton and Running (Citation1999). 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. 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 WDOE was also directed to incorporate climate change explicitly in these comprehensive assessment efforts. 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). 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. USFWS (US Fish & Wildlife Service). Thanks to Shrad Shukla, at the UW for 1/16 degree VIC model calibration over the Yakima basin. completed or are ongoing in the Columbia River Basin. Fig. However, our goal in this case was not to reduce the range of uncertainty by selecting a smaller group of GCMs. Daily and monthly streamflow for each streamflow site are provided in two formats: a) raw VIC simulations, and b) bias-adjusted simulations.

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. 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. 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 data is accessible for decision makers, researchers, students, professionals and the public. 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. Contract # DE-AC79-92BP21985. 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.

(1 April SWE and SWE2PR values were calculated using the CD VIC scenarios.). Fig. 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.

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. (2005). 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. Yakima River Basin Study Impacts of Near-Term Climate Change on Irrigation Demands and Crop Yields in the Columbia River Basin, Impacts of climate change on the state of Indiana: ensemble future projections based on statistical downscaling. These emerging needs ultimately led to the CBCCSP, and similar efforts in BC led by PCIC (Werner, Schnorbus, Shrestha, & Eckstrand, Citation2013). The CRBs cover an area over 87,000 miles 2, with an estimated volume of 50,000 miles 3, and cover about 36 percent of the state. Fig. Highs in the lower to mid 60s. The authors would like to acknowledge the contributions of two anonymous reviewers and the lead and associate editors for Atmosphere-Ocean, whose constructive suggestions substantially improved the paper during the review process. Final calibration results for the model are shown in Fig. 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.

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. Evidence includes increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level. Why is a 1C increase such a big deal? Because of space limitations, we will not be able to cover these alternative modelling efforts in this paper. Crook, A. G. (1993). The interested reader is directed to the CBCCSP report (Hamlet, Carrasco, et al., Citation2010a, Chapter 6) for a detailed discussion of methods and results. The regional report for the National Assessment was supported by two detailed water management studies focused on the CRB by Hamlet and Lettenmaier (Citation1999b) and Miles, Snover, Hamlet, Callahan and Fluharty (Citation2000). Daily streamflow data from the CD and HD downscaling methods are first processed to extract the peak daily flow in each water year of the simulations (91 years). Both calibration and validation periods were chosen to test model performance over a wide range of climate and streamflow conditions. 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.

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).. 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. 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. 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. Did you know that with a free Taylor & Francis Online account you can gain access to the following benefits? The study employs a state-of-the-art, end-to-end data processing sequence that moves from raw GCM output to a set of final hydrological products that can be accessed by the user community from a web-accessible database. Changes in PET (PET3, see Table 2) and AET (see Table 2) are shown in Fig. (Citation2010), but the essential idea behind the methods is that monthly gridded data are based only on serially complete and quality-controlled HCN and AHCCD stations (thus ensuring self-consistent long-term trends based on the same group of stations), but daily variations within the month come from re-gridded daily co-op station data, which add additional spatial detail on an event basis at daily time scales (Hamlet & Lettenmaier, Citation2005).
