columbia basin climate

Here, however, we show the same figures in metric units. 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. 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). Figures and summary tables for long-term average monthly precipitation, monthly average temperature, evapotranspiration, PET4 (Table 2), PET5 (Table 2), total column soil moisture, SWE, combined flow (runoff+baseflow). Why is a 1C increase such a big deal? Because both these effects increase flood risk in the simulations, the effects are unusually large in these basins (Fig. Rain dominant basins (DJF temperatures greater than 2C) show moderate increases in flood risk (primarily reflecting increasing storm intensity in the simulations), whereas snowmelt-dominant basins that currently flood in June show relatively little change in flood risk. A 20 percent chance of rain in the afternoon. 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). 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. Many river locations that were submitted for consideration were at gauging locations supported by the USGS and ECAN, or at locations associated with important water resources monitoring needs (e.g., checkpoints for flood control, water supply, or environmental flows) or infrastructure (e.g., dams and diversion points). Wind speed data are based on interpolated NCEP reanalysis data (Kalnay et al., Citation1996) using methods described by Elsner et al. Citation2000) were selected as the basis for the study because they provide a) a wide range of plausible outcomes while also reflecting some potential GHG mitigation by the end of the twenty-first century, and b) most of the approximately 20 GCM projections associated with the CMIP3 archived runs from both emission scenarios (Mote & Salath, Citation2010). Following the WACCIA in 2009, the WA Legislature, via the Act relating to State Agency Climate Leadership (2009), charged WDOE and other state agencies with preparing a first climate change adaptation plan for WA. The Columbia River is the fourth largest river in North America. The scope of work for the project called for hydrologic modellers at CIG to produce the following results: A suite of up-to-date hydrologic projections for the entire CRB (including portions of the basin in Canada) based on the CMIP3/AR4 (Meehl et al., Citation2007) GCM projections. In much of the CRB, however, summer AET is water limited (i.e., there is abundant surface energy to evaporate whatever water is available), and changes in AET are dominated by decreasing summer precipitation in the scenarios, which effectively decreases summer AET in most cases. 6. Impacts of 21st-century climate change on hydrologic extremes in the Pacific Northwest region of North America. 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). For each streamflow location (and its associated contributing basin area), a set of identical products is available on the study web site (CIG, Citation2013b). #! O These results support the hypothesis that widespread increases in winter landslide risks and sediment transport in rivers are likely to accompany increased winter precipitation and loss of interannual snowpack in mountain watersheds. 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. Pink bands show the range of nine or ten HD climate change scenarios for B1 and A1B emissions scenarios for three future time periods. Those who lack their own hydrologic model, but wish to make additional runs themselves, can obtain the calibrated VIC model implementation. Changes in the 1 April snowpack have been shown to depend strongly on winter temperature regimes (Hamlet, Mote, Clark, & Lettenmaier, Citation2005; Mote, Citation2006; Mote et al., Citation2005).

These include the following: Columbia River Basin Impact Assessment: Reclamation conducted the Columbia River Basin Impact Assessment to evaluate the potential effects of future climate change on river flows at 158 locations across the basin. The CBCCSP was developed to address these diverse needs. People also read lists articles that other readers of this article have read. 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. 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. 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.

Additional streamflow sites were routed from the primary VIC data, and water temperature simulations for a number of additional sites were based on temperature projections from the study. Registered in England & Wales No. Act relating to state agency climate leadership, S. 5560, 61st Legislature (WA 2009). 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. Fig. Key products from the study include summary data for about 300 river locations in the PNW and monthly Geographic Information System products for 21 hydrologic variables over the entire study domain. 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. These spatial variations in the change in AET are broadly reflective of the dominant drivers of AET in each case. 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. In other words, although at these sites the model results do not match the observations in the absolute sense (large bias), the relative changes follow the observed variations quite well (high R 2). A comprehensive website was to be developed to serve all the data produced by the study, at no cost, to the general public, management professionals agency staff members, scientific researchers, private sector consultants, etc. 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. 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). Incidence of Bactericera cockerelli (Hemiptera: Triozidae) under different pesticide regimes in the lower Columbia basin. 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. The Red Devils dropped the first game of the double-header 11-3 in five innings before . 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). 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 . Tonight Mostly cloudy. Climate change effects on stream and river temperatures across the Northwest U.S. from 1980 - 2009 and implications for salmonid fishes. 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. An understanding of the basin's transboundary nature has also informed CIG's hydrologic modelling studies, which have consistently provided complete coverage of the Canadian and US portions of the basin.
