Mayo Landscape Hazards: Geological Mapping for Climate Change Adaptation Planning
Project Completed: March 31, 2010
The goal of community-based hazards mapping projects is to identify landforms, sediments and landscape processes that may pose a threat to ongoing and future development, under current and changing climate conditions. Factors under such consideration include permafrost and ground ice; surface water drainage; surficial geology; and slope stability. These factors combine to create landscape hazards for infrastructure and foundation conditions, which may be exacerbated within a changing climate. Such insights can be used to guide investigations supporting future adaptation and town planning guidelines.
Surficial mapping studies were undertaken to determine the stability of surface sediments, detailed studies of hydrological processes; as well the characteristics of permafrost were carried out. Final hazard identification was completed by combining the results of the hydrological and permafrost studies with surficial geological mapping to create a ranking of potential landscape hazards for distinct geological units within, and surrounding, the community of Mayo. Hazard rankings also include projected changes in climate variables such as temperature, precipitation and seasonality.
The geoscience data from the various field studies and scientific reviews was used to create a final stop-light map of landscape hazards that delineate low, moderate, and high-risk areas in the Mayo region. The final report, Ranked Hazards Classification Map, and the Surficial Geology Map are all available online.
