Hydrology & Surficial Geology

Structurally damaged house resulting from permafrost degradation.

The Hydrology and Surficial Geology section applies the science of geology to understanding the engineering considerations of geologic materials and other geologic problems for society.

Here at the Alaska Division of Geological & Geophysical Surveys we determine the locations and supplies of groundwater and construction materials. We collect, analyze, and compile geologic data useful for engineering and hydrologic purposes needed for managing Alaska's water resources and building infrastructure. We also identify where geologic processes are most likely to have an impact on humans, the structures we build, and the environment.

Surficial-geologic maps portray the distribution of unconsolidated surficial-geologic materials and provide information on their engineering properties and potential as sources of construction materials and placer minerals.

Engineering-geologic maps depicting construction materials resources are useful for building infrastructure to support resource exploration and development, and for locating valuable placer-mineral deposits.

Groundwater analysis and aquifer modeling and mapping in oil and gas basins and other areas of high development potential are essential to ensuring an adequate and safe supply of water for development and resource access.
