This paperdescribes the geotechnical properties of the clayey layers that have wide exposure in the lowlands of thePersian Gulf coast. Studied layers are generally clay sized and consist of a lesser percentage of clay minerals.Most of the clayey layers have intermediate plasticity, and low potential for expansion. The variation ofphysical and engineering properties of the layers from base to top and along the Bahmanshir River isinvestigated in this research. The engineering properties of the beds seem to be affected by tidal and riverflow currents and totally by their formation sedimentary environments. Links of the geotechnical data withgeological features as formation sources in the upstream of the basin, the cementation due to the capillaryfeature in the floodplain sub-environment and the flocculated texture of clays in the brackish water, have been discussed in this paper. Overall, it is observed that the geotechnical data could be correlated with thegeological features of the Bahmanshir Series.
