Experiences gathered from geophysical surveying in five small Harbour yards, SW Sweden

Summary Small-scale harbour yards are attractive locations for land development, and they are currently being subjected to large investments and adaption to raising sea levels. This abstract aims at showcasing the use of electrical resistivity measurements as well as single and multichannel ground penetrating radars under varied geotechnical, hydrogeologic and contaminant conditions in the nearshore transition zone. An optimal balance between drilling, geophysics and marine surveying is key in the early stages of such development projects as several potential obstacles may otherwise cause costly surprises later. Arguably geophysical surveying from land and small boats can decrease the need for near-shore drilling while maintaining project quality and adding detail.
