Land reflection seismic, hydrogeological and magnetic study of an area prone to quick-clay landslides in southwest Sweden
https://doi.org/10.57804/hxj1-8b75
Quick-clay landslides are common geohazards in Nordic countries and Canada. The presence of potential quick clays is confirmed using geotechnical investigations, but near-surface geophysical methods, such as seismic and resistivity surveys, can also help identifying coarse-grained materials associated to the development of quick clays.
We present the results of four reflection seismic profiles next to the Göta River in Sweden, along which many quick-clay landslide scars exist. An extensive coarse-grained layer exists in the sedimentary sequence and is interpreted and modeled in a regional context. Hydrological modeling of the coarse-grained layer is performed. Magnetic data are also studied within this investigation.
Four reflection seismic profiles collected in 2013 (line 5 has two parts, cabled geophones and wireless stations).
