These data are summarized in figures and tables prepared for each streamflow site discussed in Section 4.

Les plus fortes augmentations dans les crues sont dans les bassins de pluie et neige mles dont les tempratures actuelles au milieu de l'hiver sont quelques degrs du point de conglation. Differences in the impacts in the US and Canadian portions of the basin are striking, confirming results reported in two previous studies (Hamlet, Citation2003; Hamlet & Lettenmaier, Citation1999b).

Summary information and statistics: geographic location, basin area, calibration statistics (if available), links to the USGS or ECAN websites, and so forth. But as researchers continue to fine tune climate models, shifting demand for water now must be accounted for, say Washington State University scientists. Bias corrected inflows were produced to support the GENESYS and HYDSIM reservoir operations models, which are used by the NWPCC and BPA, respectively, for main-stem studies in the CRB (e.g., NWPCC, Citation2005). Building the Columbia Basin-Boundary Region's Capacity to Adapt to Climate Change. A number of sub-basins are nested within each other, as shown in the right panel along with their relative sizes. Until recently, a climate-change induced shift in water supply was the story of the Columbia River Basin's future. Gridded meteorological datasets (daily total precipitation and maximum and minimum daily temperature) at 1/16 degree latitude-longitude resolution (approximately 7km by 5km) were constructed for the study from observed station records for the period 1915 to 2006. Each of the six panels in the figure shows the long-term monthly mean for the 10 (9 for B1) HD GCM scenarios (red lines) and the historical simulations (blue lines). If neither naturalized nor modified flow is available, no bias-adjusted data were provided. The largest increases in flooding are in mixed-rain-and-snow basins whose current mid-winter temperatures are within a few degrees of freezing. Blue lines show average historical values (19162006) (repeated in each panel). Lows in the upper 30s to lower 40s. 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. 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. Columbia River Basin Basin Overview . 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.

For each streamflow location (and its associated contributing basin area), a set of identical products is available on the study web site (CIG, Citation2013b). Saturday Night And Sunday: Cloudy with a 50 percent chance of rain. A comprehensive assessment of hydrologic extremes such as Q100 and 7Q10. 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. 2013a. 12). 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. 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. Full knowledge of the preceding steps is not required to use the products obtained at any level of the study, which increases the utility of the products. 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. Among its most useful features is the predominantly physical basis of the model, which largely avoids concerns about parameter stationarity in a changing climate. These extended meteorological data have proved particularly useful in supporting ecological studies (e.g., Littell et al., Citation2010). are estimated by the VIC hydrologic model (discussed below) using empirical methods described by Kimball, Running and Nemani (Citation1997) and Thornton and Running (Citation1999). Lows in the lower 50s. 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). Weather for Monday, Feb. 27. Source: NOAA Fisheries. The CBCCSP had a budget of about US$500 thousand (in 2010 dollars) over two years. Cooper, R. M. (2002). 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. This is a good example of the use of the study data to support relatively fine-scale planning needs. 6. 1990 level modified streamflow 19281989. 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).

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. Littell, J. S., Elsner, M. M., Mauger, G. S., Lutz, E. R., Hamlet, A. F., & Salath, E. P. (2011). 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). Note the relative insensitivity of SWE to warming in the coldest, and most heavily snowmelt-dominant, areas in the northern tip of the CRB in British Columbia in comparison with the rest of the domain. Northeast wind 5 to 10 mph. Sunday Night: Mostly cloudy with a 20 percent chance of rain. The VIC model has been widely applied in climate change studies at both the regional scale (e.g., Christensen & Lettenmaier, Citation2007; Lettenmaier, Wood, Palmer, Wood, & Stakhiv, Citation1999; Maurer, Citation2007; Maurer & Duffy, Citation2005; Payne et al., Citation2004; Van Rheenen, Wood, Palmer, & Lettenmaier, Citation2004) and global scale (e.g., Adam, Hamlet, & Lettenmaier, Citation2009; Nijssen, O'Donnell, Hamlet, & Lettenmaier, Citation2001). The approach used a refined version of the methods established by Hamlet and Lettenmaier (Citation2005), which created a hybrid historical meteorological dataset based on three primary data resources: a) monthly HCN data in the United States and the similar AHCCD datasets in Canada, b) daily data from the cooperative station network in the United States (co-op stations) and similar data from Environment Canada, and c) a monthly climatology (19712000) for precipitation and daily minimum and maximum temperatures at 30 arc-second resolution produced using the PRISM (Daly, Gibson, Taylor, Johnson, & Pasteris, Citation2002; Daly, Neilson, & Phillips, Citation1994; DiLuzio, Johnson, Daly, Eischeid, & Arnold, Citation2008).
