Landscape Hazard Maps for Dawson Community Under Future Climate Conditions

Dawson, Yukon landscape hazard maps assess geological risks like landslides, permafrost stability, and flooding. The maps integrate multiple data inputs including surficial geology, topography, permafrost distribution, and future climate projections. They are designed in stoplight colors to support community land-use and adaptation planning.

Use Cases

• Identify areas of permafrost stability risk for infrastructure planning using integrated permafrost distribution data.
• Model landslide susceptibility by analyzing topography (slope and aspect) layers against surficial geology.
• Assess flood hazard potential under changing future conditions by incorporating hydrological trend analyses and climate projections.
• Support land-use management decisions by interpreting the stoplight-colored hazard map within an adaptation planning framework.

Strengths

• Maps are based on integration of multiple specialized data sets including ground penetrating radar and borehole data.
• Includes future climate projections to assess potential hazards under changing conditions.
• Accompanied by a detailed report and a surficial geological map describing landscape characteristics and methodology.

Limitations

• Spatial coverage is limited to the Dawson community area in Yukon, Canada.
• Data is presented as map services (ESRI REST) rather than a tabular dataset, limiting direct statistical analysis.
