Project Spotlight: Rivers Climate Change Indicators
In August of 2017, interactive maps that show changes to the timing and volume of river flow, using data from analysis performed at PCIC, were published. These accompany updates to a British Columbia (BC) Ministry of Environment and Climate Change Strategy (MoECCS) report on climate indicators in BC, to which PCIC has also contributed. Rivers and the ecosystems that they support provide a variety of services to communities in the province. Changes to river flow can result in impacts, such as floods, that affect these services.
Seventeen stations—places where river flow data is recorded using gauges—were suitable for trend analysis, six with records extending back for about 100 years and 11 with records for about the last 50 years. Most stations showed significant increases in minimum daily flow and insignificant decreases in maximum daily flow over 1912-2012, while the magnitude and direction of change in mean annual and seasonal flow varied by river basin. Changes in river flow depends on a basin’s location, size, elevation, and flow regime. Changes in flow volume for the 55-year period, 1958-2012, were similar to those f Referee of the Journals...
