Because both these effects increase flood risk in the simulations, the effects are unusually large in these basins (Fig.
Columbia Basin Care It reaches a thickness estimated at 16,000 feet in places. 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. 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. Pink bands show the range of nine or ten HD climate change scenarios for B1 and A1B emissions scenarios for three future time periods.

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. Nakienovi, N., Alcamo, J., Davis, G., De Vries, B., Fenhann, J., Gaffin, S.,Dadi, Z. Naturalized and modified streamflow data were used to produce bias-corrected streamflow realizations (see below). 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 . A calibrated 1/16 degree latitude-longitude resolution implementation of the VIC hydrologic model over the Columbia River basin was used to produce historical simulations and 77 future hydrologic projections associated with three different statistical downscaling methods and three future time periods (2020s, 2040s, and 2080s). 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. 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). Les simulations dcoulements de crue et dtiage augmentent en intensit pour la plupart des sites fluviaux compris dans cette tude. 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). Since 2014, the RDI has engaged in applied research related to community climate adaptation. Statistics for hydrologic extreme events (as discussed above) are presented in a different format, shown in Fig. Simulations of floods and extreme low flows increase in intensity for most of the river sites included in the study. Cooper, R. M. (2002). The multi-model ensemble 30-year mean annual temperature increases by 2.8 C (5.0 C) by late 21st century under RCP4.5 (RCP8.5) over the 1979-1990 baseline, with 18% (24%) more warming in summer. Each product is provided as a gridded file (one file for each variable and calendar month) in ASCII format. 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. Results from the study show profound changes in spring snowpack and fundamental shifts from snow to rain-dominant behaviour across most of the domain. A family of greenhouse gas emissions scenarios used in the IPCC effort (Nakienovi et al. Columbia Basin Care is the region's only independent nonprofit skilled nursing facility for long-term care and short-term rehabilitation. 2013b. These extended meteorological data have proved particularly useful in supporting ecological studies (e.g., Littell et al., Citation2010). 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. The VIC model (version 4.0.7) was implemented at 1/16 degree resolution, with three active soil layers and up to five elevation bands with an approximate spacing of 500m. The model was run in water balance mode with a snow model time step of 1h and a water balance time step of 24h. The model was coupled to a simple daily-time-step routing model (Lohmann, Raschke, Nijssen, & Lettenmaier, Citation1998), which was used to produce daily flow estimates at each of the approximately 300 streamflow locations included in the study. 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).
Climate Change Impacts on the Columbia Basin 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). 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. Special thanks to Kurt Unger and Ken Slattery, who were the primary architects of the CBCCSP at WDOE. 6. For information on past projects, see our Projects Archive. Mostly cloudy, with a high . Elsner MM, et al. Hamlet, and S.-Y. Bias adjustment was also used in preparing the specific reservoir modelling support products discussed below. Fig. Atmosphere Ocean 51. Fig. Columbia Basin Dive Rescue has been serving the community for almost 50 years. Detailed water balance summaries and streamflow data for up to 300 river locations to be specified by WDOE and other stakeholders in the region. The bias-corrected monthly values are then used to rescale the simulated daily flow sequences produced by the hydrologic model to produce bias-corrected daily streamflows. Click the download link to get the current station data. The largest reductions in low flows occur west of the Cascade Range in the simulations. Twenty-one daily time-step output variables were archived for the VIC simulations (Table 2). 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. Incidence of Bactericera cockerelli (Hemiptera: Triozidae) under different pesticide regimes in the lower Columbia basin. This choice was imposed by WDOE. Thus, each site is bias-corrected using either naturalized or modified flow but not both.

Hamlet, and S.-Y. The PRISM data for Canada were interpolated to 30 arc-second resolution data from a 2.5 arc-minute (approximately 4km) product and were statistically adjusted to remove the bias associated with the different time period (19611990 means for the 4km product). But as researchers continue to fine tune climate models, shifting demand for water now must be accounted for, say Washington State University scientists. Note that unlike the raw VIC flux files discussed above (Table 2), imperial units are used for these products on the study website (cubic feet per second, inches, degrees Fahrenheit). Daily and monthly streamflow for each streamflow site are provided in two formats: a) raw VIC simulations, and b) bias-adjusted simulations. Building the Columbia Basin-Boundary Region's Capacity to Adapt to Climate Change. About 50 of the 80 sites evaluated show monthly NSE scores greater than or equal to approximately 0.7 (good to excellent fit). Impacts assessments from the WACCIA played a central role in these planning activities, but updated and extended data from the CBCCSP also materially supported these efforts. 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. Climate change effects on stream and river temperatures across the Northwest U.S. from 1980 - 2009 and implications for salmonid fishes. Naturalized streamflow data were used exclusively in the CBCCSP to calibrate the hydrologic model.

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). The study also used the ColSim reservoir operations model (Hamlet & Lettenmaier, Citation1999b) to estimate water deliveries to the Columbia Basin Project (the primary irrigation project supplied by water from Grand Coulee Dam) under future climate scenarios using streamflows generated by the integrated VIC/CropSyst model. Isaak DJ et al. 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). 2012.

Fig. 5 Howick Place | London | SW1P 1WG. Starting from these parameter sets, an additional large-scale calibration was performed during the CBCCSP to improve model performance in reproducing historical streamflow. Les rsultats de ltude montrent de profonds changements dans l'accumulation de neige au printemps et des dplacements radicaux de neige ou pluie et neige mles vers principalement pluie dans presque tout le domaine.

Guarant do Norte, Mato Grosso, Brazil Today, Tonight & Tomorrow's Associated shifts in streamflow timing from spring and summer to winter are also evident in basins that currently have significant snow accumulation in winter, whereas rain-dominant basins show minimal shifts in streamflow timing. To support ecosystem research and impacts assessment, CIG extended the project to include specific meteorological and hydrological variables needed to support ecological studies (see discussion in Section 3). Treaty Relating to Cooperative Development of the Water Resources of the Columbia River Basin, United States of AmericaCanada, January 17, 1961September 16, 1964, 15 U.S.T. (2000). The largest increases in flooding are in mixed-rain-and-snow basins whose mid-winter temperatures are presently within a few degrees of freezing. Figures and summary tables for flood statistics and low-flow statistics. The largest changes in flood risk are simulated in mixed-rain-and-snow basins.
Columbia River Basin Impacts Assessment, PN Region - usbr.gov This is a good example of the use of the study data to support relatively fine-scale planning needs. Retrieved from, CIG (Climate Impacts Group). In particular, it is clear that Canada will have not only about 50% of the reservoir storage in the CRB (Hamlet, Citation2003) but also an increasingly dominant portion of the natural water storage as snowpack in the future. 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. The interested reader is directed to the CBCCSP report (Hamlet, Carrasco, et al., Citation2010a, Chapter 6) for a detailed discussion of methods and results. 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. Highs around 80. (2010). 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. Inset numbers at the upper left in the future projections are the percentage changes in 1 April SWE averaged over each grid cell in the entire domain. Des accroissements gnraliss simuls de la rhumidification du sol en automne et en hiver dans les secteurs o l'accumulation de neige en hiver est importante (sous le climat actuel) appuient les hypothses de risque accru de glissement de terrain et de transport de sdiments durant l'hiver dans le futur. Also, at about this time, successful lawsuits challenging NEPA studies because they had not addressed climate change effects began to appear (Hamlet, Citation2011). A low pressure system slowly moving offshore is forecast to spin moisture into the Columbia Basin Sunday as it meanders closer to the Southern Oregon Coast. 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 BCSD runs are transient runs from 1950 to 2098 or 1950 to 2099 (depending on the GCM). This daily disaggregation technique sometimes introduces an undesirable discontinuity in the bias-corrected daily values at the beginning and end of months. In addition to the time series gridded data, the long-term monthly mean data for each hydrologic variable, for each scenario, is provided in GridASCII format, compatible with ArcGIS. Climatic Change 113:499-524. Produced by, Clean Energy and Green Building Major Projects, Private and public sector clean energy and green building construction projects valued at $15M or more for the 3rd quarter of each year. For example, researchers who wish to run their own hydrologic models can do so by downloading the statistically downscaled meteorological forcings from the study. 10 Left panel: Changes in Q100 for 297 streamflow locations expressed as a ratio of Q100 for the future period to Q100 for the historical period based on the average of the nine or ten HD scenarios for the B1 and A1B emissions scenarios for three future time periods. Saturday Night And Sunday: Cloudy with a 50 percent chance of rain. Regional summaries were prepared by Tohver et al. (Citation2010) over the entire PNW (Tohver et al. Changes in PET (PET3, see Table 2) and AET (see Table 2) are shown in Fig. Right panel: Historical estimates of summer AET (upper right) compared with percentage changes for the same CD scenarios. 2), for which overall errors in meteorological driving data were assumed to be relatively small; then, using these model parameters, to check the results in smaller sub-catchments. Tague, Grant, Farrell, Choate and Jefferson (Citation2008) showed analogous differences between watersheds in the PNW based on the relative contribution of groundwater to base flows. 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. Calibration of the VIC model was carried out using an automated calibration tool called MOCOM-UA developed by the Land Surface Hydrology group at the UW, following the approach described by Yapo, Gupta, and Sorooshian (Citation1998). Red dots indicate sites that are essentially unimpaired by human use or for which there is estimated modified* or naturalized flow. 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). The Assessment was initiated in June 2013 and is expected to completed in December 2015. .. slide 2 of 5. 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. For each streamflow location (and its associated contributing basin area), a set of identical products is available on the study web site (CIG, Citation2013b). Wind speed data are based on interpolated NCEP reanalysis data (Kalnay et al., Citation1996) using methods described by Elsner et al. The CBCCSP provided climate change projections of meteorological drivers and a calibrated VIC implementation in support of the study. Either naturalized or modified flows (Crook, Citation1993) are used for bias correction of data provided in the site-specific products discussed below, with naturalized data taking precedence if available.
