Description :
The AA. investigated the effectiveness of a multi-receiver apparent electrical conductivity (ECa) survey for mapping the trace of tidal paleochannels in the western part of the coastal plain of Belgium. From a limited number of augerings, a three-layered soil was observed. A fitting procedure allowed modelling the conductivities of both subsurface layers, after which the 4 simultaneous ECa measurements were combined to model the depth of the interfaces between the three layers. The predictions were validated by depth observations along a 150 m transect. This methodoly allowed a precise prediction of the depth of the interfaces between the contrasting layers in this three-layered soil.
