Description

Mosvatnet is a lake located within Stavanger, Norway, and it is considered a national bird sanctuary. In the eastern side of the lake lies an islet that acts as a bird nesting ground. The expansion of Stavanger has forced more construction of important transport infrastructure. Such urban developments have altered the lake footprint and the surrounding landscape along with the geological record. For example, aerial imagery has revealed that the eastern shoreline of the lake has artificially prograded about 100 m since the mid-1930s.

Urban landscape affects species of plants and animals. Therefore, urban planning of smart cities contributes to preserving wildlife and biodiversity within those urban areas. The Stavanger municipality plans to extend the Mosvatnet islet by one third to provide a larger habitat for migrating birds. The project requires conducting advanced geotechnical investigations in the surface and subsurface to analyse feasible and cost-effective technical solutions.

The present study delivers a geological model of Mosvatnet subsurface and provides a basis for further geotechnical studies. However, modelling natural geological structures in this area is challenging due to environmental restrictions, lack of natural rock exposures, and the presence of artificial infill material added by anthropogenic activities over time.

To generate the model, we employed non-invasive and environmentally-friendly techniques that were combined with public data collected by the Norwegian government. This interdisciplinary study involves geomatics, geotechnics, geophysics, and geology. It integrates historical aerial imagery, light detection and ranging (LiDAR), on- and off-shore ground penetrating radar (GPR), geotechnical boreholes, and geological field mapping.
