Station Hydrologic Model Output

The Station Hydrologic Model Output page provides access to simulated streamflow data for locations throughout British Columbia, Canada. The streamflow data were simulated using runoff and baseflow generated with an upgraded version of the Variable Infiltration Capacity (VIC-GL) model that is coupled to a glacier model (Schnorbus, in prep) and routed with RVIC (Lohmann et al., 1998, 1996; Hamman et al., 2016).

The simulated data includes daily streamflow time series for 190 locations corresponding to a combination of Water Survey of Canada and US Geological Survey hydrometric gauges and dam sites in the Peace, Fraser and Columbia watersheds. For each site, streamflow for the historical run, as driven by PCIC's gridded meteorological data for northwest North America (PNWNAmet), is available from 1945 to 2012. Additionally, streamflow for 12 scenarios, as driven by six GCMs from the Coupled Model Intercomparison Project Phase 5 (CMIP5; Taylor et al., 2011) run under two Representative Concentration Pathways (RCPs), 4.5 and 8.5, statistically downscaled with the Bias Correction/Constructed. Analogues with Quantile mapping reordering (BCCAQ) method  using PNWNAmet as the target, is available from 1945 to 2099. See Gridded Hydrologic Model Output for more details on Global Climate Model (GCM) selection and downscaling. The simulated data represents naturalized flow conditions (i.e. with effects of upstream regulation removed) for those sites affected by storage regulation.

 

Simulated data includes routed Daily Streamflow (m3s-1).

Usage Notes

One CSV file that contains streamflow for the PNWNAmet historical run and 12 CMIP5 scenarios is provided for each station. The first column is the date, followed by PNWNAmet-driven streamflow and then a column each for the 12 CMIP5 scenarios listed by GCM/RCP/run (i.e. ACCESS1-0_rcp85_r1i1p1). Streamflow is provided in cubic metres per second (m3 s-1).

To test the ability of the VIC-GL RVIC model to replicate streamflow in your watershed of interest, compare PNWNAmet values to observed streamflow. To look at the impact of climate change on streamflow, it is suggested that one compare the future to the past within the same GCM/RCP/run, such as mean daily streamflow from 2041-2070 versus 1971-2000 for ACCESS1-0_rcp85_r1i1p1.  

The user interface features an interactive map of northwestern North America that allows users to zoom, pan and select their region of interest using a rectangular selection tool. Alternatively, stations can be selected by Water Survey of Canada station name or ID, US Geological Survey station name or ID, dam or project site.
