Surficial Hydrogeological Materials

Surficial Hydrogeological Materials Surficial hydrogeological materials show the distribution of sediment deposited in glacially influenced environments. Most drinkable groundwater resources in Canada occur in shallow surficial-sediment aquifers. Surface sediments, such as gravel, sand, silt and clay, or mixed sediments, are an important control on vegetation patterns and surface-water recharge to aquifers. In addition, areas with significant thicknesses of sand and gravel-large moraines and buried valleys-often host prolific aquifers. 2022-03-14 Natural Resources Canada geoinfo@nrcan.gc.ca Form DescriptorsNature and EnvironmentScience and Technologyenvironmentgeologygroundwaterhydrologymap Download the English JP2 File through HTTPJP2 https://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_6_ed/eng/6407_surficial_hydrogeological_materials.jp2 Download the English ZIP (PDF,JPG) file through HTTPZIP https://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_6_ed/eng/6407_surficial_hydrogeological_materials.zip Download the French JP2 File through HTTPother https://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_6_ed/fra/6407_materiaux_superficiels_hydrogeologiques.jp2 Download the French ZIP (PDF, JPG) File through HTTPZIP https://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_6_ed/fra/6407_materiaux_superficiels_hydrogeologiques.zip
