Abstract
This paper presents new results of geophysical measurement in coastal area of Nam Dinh province. Resistivity imaging was carried out to map the resistivity distribution along a 2 km long profile. Two boreholes were drilled on the same profile. The resistivity of 26 soil samples was determined in laboratory. A comparison between the resistivity of well logging, resistivity imaging and samples shows a good agreement. The resulting resistivity section provides promising 2D image of geological structures. Regarding the resistivity values, fresh water bearing areas can be identified in the Holocene and Pleistocene aquifers. Resistivity imaging has proved to be an appropriate tool to investigate hydrogeological structures in coastal areas.
