| Abstract | Buried valleys occur across Canada yet no systematic study has been completed of the scale, style, and hydrogeological significance of this aquifer type. This paper reviews geological and
hydrogeological knowledge of buried-valley aquifers in Canada. Buried valleys are placed in a stratigraphic classification: i) bedrock, ii) bedrock interface, and iii) Quaternary sediment. The distribution, geometry and scale of valleys and the
sediment facies of valley fills are briefly discussed. Important hydrogeological characteristics for buried-valley aquifers include aquifer extent, aquifer continuity and several hydraulic characteristics that influence flow and hydraulic response.
The wide range of hydrogeologic settings and functions for buried-valley aquifers explains their variability as groundwater resources, thus emphasizing the need for greater monitoring and understanding of buried valleys at several scales. Knowledge
gaps are identified and the need for improved integration of geological and hydrogeological studies to improve understanding of Canada's buried-valley aquifers is advocated. |
