Water yield variability index, selected drainage regions, 1971 to 2013 This product provides the variability index for selected drainage regions in Canada. Variability is measured using a coefficient of variation (CV) to compare all months over a 42-year time period and is a measure of the dispersion or variation in the monthly yield values from 1971 to 2013 (and 1971 to 2012 for drainage region 1). It is defined as the ratio of the standard deviation to the mean or the standard deviation divided by the mean, with higher CVs indicating more variability in monthly water yields. The monthly variability was not calculated for drainage regions 5, 7, 8, 16, 17, 18, or the Labrador portion of 25. 2017-03-21 2019-09-17 Statistics Canada francois.soulard@canada.ca Nature and EnvironmentWater yield variability indexGeographic dataSurface waterWaterFresh waterWater supply Water yield variability index spatial data files (Bilingual)FGDB/GDB http://ftp.maps.canada.ca/pub/statcan_statcan/Fresh-water_Eau-douce/freshwater-variability_variabilite-eau-douce/Freshwater_Eau_douce_Canada.gdb.zip Water yield variability index, selected drainage regions, 1971 to 2013, release in Human Activity and the Environment: Freshwater in Canada (map) (English)HTML http://www.statcan.gc.ca/pub/16-201-x/2017000/sec-2/m-c/m-c-2.2-eng.htm Water yield variability index, selected drainage regions, 1971 to 2013, release in Human Activity and the Environment: Freshwater in Canada (map) (French)HTML http://www.statcan.gc.ca/pub/16-201-x/2017000/sec-2/m-c/m-c-2.2-fra.htm Human Activity and the Environment 2016: Freshwater in Canada (full publication) (English)HTML http://www.statcan.gc.ca/pub/16-201-x/16-201-x2017000-eng.htm Human Activity and the Environment 2016: Freshwater in Canada (full publication) (French)HTML http://www.statcan.gc.ca/pub/16-201-x/16-201-x2017000-fra.htm Human Activity and the Environment 2016: Freshwater in Canada (full publication) (English)PDF http://www.statcan.gc.ca/pub/16-201-x/16-201-x2017000-eng.pdf Human Activity and the Environment 2016: Freshwater in Canada (full publication) (French)PDF http://www.statcan.gc.ca/pub/16-201-x/16-201-x2017000-fra.pdf Human Activity and the Environment: Freshwater in Canada, release in the The Daily, Statistics Canada’s official release bulletin (overview) (English)HTML http://www.statcan.gc.ca/daily-quotidien/170321/dq170321b-eng.htm Human Activity and the Environment: Freshwater in Canada, release in the The Daily, Statistics Canada’s official release bulletin (overview) (French)HTML http://www.statcan.gc.ca/daily-quotidien/170321/dq170321b-fra.htm Water yield variability index, selected drainage regions, 1971 to 2013WMS https://webservices.maps.canada.ca/arcgis/services/StatCan/Freshwater_Variability_En/MapServer/WMSServer?request=GetCapabilities&service=WMS&layers=0&legend_format=image/png&feature_info_type=text/html Water yield variability index, selected drainage regions, 1971 to 2013WMS https://servicesweb.cartes.canada.ca/arcgis/services/StatCan/Freshwater_Variability_Fr/MapServer/WMSServer?request=GetCapabilities&service=WMS&layers=0&legend_format=image/png&feature_info_type=text/html Water yield variability index, selected drainage regions, 1971 to 2013ESRI REST https://webservices.maps.canada.ca/arcgis/rest/services/StatCan/Freshwater_Variability_En/MapServer/0 Water yield variability index, selected drainage regions, 1971 to 2013ESRI REST https://servicesweb.cartes.canada.ca/arcgis/rest/services/StatCan/Freshwater_Variability_Fr/MapServer/0
