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). Jordskred av kvicklera är vanliga "geohazards" i Norden och Kanada. Närvaron av potentiella kvickleror bekräftas med hjälp av geotekniska undersökningar, men geofysiska metoder i närheten av ytan, såsom seismiska och resistivitetsundersökningar, kan också bidra till att identifiera grovkornigt material i samband med utvecklingen av kvickleror. Vi presenterar resultaten av fyra reflexions-seismiska profiler bredvid Göta älv i Sverige, längs vilka många jordskred av kvicklera finns. Ett omfattande grovkornigt lager finns i sedimentärsekvensen och tolkas och modelleras i ett regionalt sammanhang. Hydrologisk modellering av det grovkorniga skiktet utförs. Magnetiska data studeras också inom denna undersökning. info:eu-repo/semantics/openAccess SE http://sws.geonames.org/3337386 Uppsala University Uppsala universitet 2025-01-17T10:38:53.772559Z eng
