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, by selecting 10 GCM scenarios with good historical performance that also spanned the range of impacts, we effectively reduced the computational and storage requirements of the CBCCSP by approximately a factor of two. 'High Uncertainty' is indicated when Mahalanobis Distance is >1. 2 Eleven sub-basins in the CRB used for large scale calibration (left panel). Changes in snowpack are a key driver of hydrologic impacts in the PNW (Elsner et al., Citation2010; Hamlet & Lettenmaier, Citation1999b). These areas are so cold in winter (DJF average on the order of -10C temperature) that a change in temperatures of 23C has relatively little effect on seasonal snow accumulation in the 2020s and 2040s. 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. Home | Columbia Basin Climate Source 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). A 20 percent chance of rain showers in the evening. The Columbia Basin Climate Source is your one-stop destination for information about climate change, impacts, and action in this region. Monthly hydrographs in different portions of the domain primarily reflect changes in snow accumulation and melt processes and seasonal changes in precipitation (generally wetter falls, winters, and springs and drier summers).

Sites without modified or natural flow estimates are shown in yellow. Text files (six per figure) providing all the ensemble data used to construct each panel in the figure are also provided on the CBCCSP website. 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. Retrieved from, Climate change and resource management in the Columbia River Basin.

Clima em Guarant do Norte, Mato Grosso - weather.com 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. 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). 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. 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). 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. Those who wish to do additional post-processing of the existing VIC data can access the archived model output. 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. Instead our primary goal was to encompass the approximate range of all available scenarios while reducing costs by downscaling projections from a subset of the larger group of 20 GCMs (Hamlet et al., 2010a). 8).

These products are based solely on the CD and HD projections listed in Table 1. Thus, each site is bias-corrected using either naturalized or modified flow but not both. 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. But as researchers continue to fine tune climate models, shifting demand for water now must be accounted for, say Washington State University scientists. By that same year, a large number of natural resources management agencies in the US federal system (e.g., the USFS, USNPS, USBR, USFWS, FERC, FEMA, NMFS) were actively engaged in educating and training their upper-level leadership and staff about climate change and were attempting to acquire appropriate data and information to support long-term planning and develop long-term climate change adaptation strategies. Detailed forecast for Upper Columbia Basin Tonight Mostly clear. The RMJOC is specifically dedicated to reviewing the practices, procedures, and processes of each agency to identify changes that could improve the overall efficiency of the operation and management of the Federal Columbia River Power System projects. Although results could potentially vary in different areas of the model domain, these results support the hypothesis that only modest improvements in validation statistics would result from individual calibration of additional streamflow sites within each sub-basin. 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. Climate Adaptation | Columbia Basin Rural Development Institute Has spring snowpack declined in the Washington Cascades?

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. Each product is provided as a gridded file (one file for each variable and calendar month) in ASCII format. This approach was partly based on practical limitations on time and computational resources but was also informed by previous experience using the VIC model at finer spatial scales. Many locations could see increases of 100% or more in the 50-year and 100-year flood magnitude, with some smaller tributaries potentially seeing increases of as much as 175%. Small black dots indicate streamflow sites where naturalized flows were not available.

The CBCCSP provided climate change projections of meteorological drivers and a calibrated VIC implementation in support of the study. Building the Columbia Basin-Boundary Region's Capacity to Adapt to Climate Change. Naturalized and modified streamflow data were used to produce bias-corrected streamflow realizations (see below).

Results from the study show profound changes in spring snowpack and fundamental shifts from snow and mixed-rain-and-snow to rain-dominant behaviour across most of the domain. The most sensitive basins are mixed-rain-and-snow basins. West-wide studies to support USFS and USFWS needs (including current efforts to include California) will have a budget of less than half this amount, a level of efficiency that would not have been achievable without the CBCCSP pilot effort. unpublished manuscript). Since 2014, the RDI has engaged in applied research related to community climate adaptation. 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). The HD method was also selected as the basis for the main summary products derived for each river location (see description below), primarily because it was capable of providing good performance over the complete range of products produced by the CBCCSP (Hamlet et al., 2010a). Columbia River | Location, Length, History, & Facts | Britannica These lands are those without any sort of status that provides government protection, such as an indigenous territory, or that have not . To explore how much the model simulations might be improved by additional fine-scale calibration, we also recalibrated three additional smaller sites within the Pend Oreille River basin. As mentioned above, 20062007 was something of a turning point for regional stakeholders considering future actions to prepare for climate change. 8) and warmer and drier summers (which increase PET) (Fig. The dark red lines show the average of the climate change ensemble. In addition, some observed streamflow data are suitable for use as natural data if the effects of storage and diversions are relatively small (e.g., for the USGS Hydro-Climatic Data Network streamflow sites). Colombia - Climate | Britannica Changes in PET (PET3, see Table 2) and AET (see Table 2) are shown in Fig. 2860, 59th Legislature (WA 2006).

Cited by lists all citing articles based on Crossref citations.Articles with the Crossref icon will open in a new tab. The Columbia River is the fourth largest river in North America and the largest river in the Pacific Northwest. 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. Detailed forecast for Lower Columbia Basin of Washington Rest Of Today Partly sunny. 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. 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). About 15 sites in western Washington, outside the CRB, were also included in support of the 2009 WACCIA.

Regional summaries were prepared by Tohver et al. Act relating to state agency climate leadership, S. 5560, 61st Legislature (WA 2009). 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. 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.

Additional products such as bias-adjusted inflow sequences for specific reservoir operations models are also included. Elsner et al. By late 21st century, annual precipitation increases by 5% (8%), with an 8% (14%) winter increase and a 4% (10%) summer decrease, but because . Hydrology and water resources research at CIG was particularly focused on the use of experimental climate and hydrologic forecasts for the CRB (Hamlet & Lettenmaier, Citation1999a, Citation2000; Lettenmaier & Hamlet, Citation2003; Leung, Hamlet, Lettenmaier, & Kumar, Citation1999) in the context of decision support for various water management applications (Hamlet, Huppert, & Lettenmaier, Citation2002; Lee, Hamlet, Fitzgerald, & Burges, Citation2011; Voisin et al., Citation2006). The process was also significantly improved by researchers at PCIC who reconfigured and optimized the code to run more efficiently on a Linux cluster (Schnorbus, Bennett, Werner, & Berland, Citation2011). 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. Here we will review a few important aspects of the basic implementation to help orient the reader and will then focus most of our attention on the additional implementation and calibration tasks carried out during the CBCCSP.

Cooper, R. M. (2002). During initial model development steps, Elsner et al. The changes in the importance of snow in some areas of the United States are particularly striking. 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. These annual peak daily flows are then ranked and assigned a quantile value using an unbiased quantile estimator based on the method of Cunane (Stedinger, Vogel, & Foufoula-Georgiou, Citation1993). These approaches are also useful for avoiding biases in the streamflow simulations that result from systematic errors in gridded precipitation or temperature data. 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. All of the meteorological forcing data, except wind speed, are reproduced in the output files produced by the hydrologic model. 95 0 obj <> endobj NWAC Softball: Lower Columbia splits double-header at Yakima Valley to Impacts of 21st-century climate change on hydrologic extremes in the Pacific Northwest region of North America.
