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. Sweden Sverige Other Access to data through SND. Data are freely accessible. Åtkomst till data via SND. Data är fritt tillgängliga. openAccess
