This paper proposes a geophysical survey, consisted of onshore and into shallow water (intertidal or surface zone) geoelectrical resistivity tomography (ERT) to define the buried lithologies and geometry of the sedimentary structures. The study area is localized on the Solent estuarine system at the southern margin of the Hampshire Basin (Fareham, England), an elongated asymmetrical downwarp with mainly Tertiary deposition. The Lower Cretaceous Wealden Beds, which consist of freshwater marls and estuarine/shallow marine shales, are the oldest outcropping strata. These beds are overlain by Lower Greensand and shallow marine clays and sands of theAlbian Gault and Upper Greensand. The actual Solent System is the result of the middle section of the Holocene ‘Solent River’ system, a lowland riverine system which,
