From: From river flow regime diversity to proxies for hydrologic homogeneity a Canada-wide case study

Hydroclimate and physiographic characteristics of the study areas. Study areas do not span the entirety of Canada but are rather constrained to the interior of 2531 catchment polygons. Across the study areas, maps show the spatial variability of: (A) climate regime based on the Köppen climate classification, (B) elevation based on the DEM, (C) land cover, (D) percent clay content in topsoil, (E) percent clay content in subsoil, and (F) surface water occurrence.
