Core P11, which we drilled in the lowermost swampy region of the Peneus River floodplain south of Gastouni, behind a broad coastal barrier dune field, sheds considerable light on the pre-diversion morphology of the region.
Currently, the Peneus River carries a large volume of sediment into the Ionian Sea.
Our studies of the strandline on the northwest coast of Elis were limited to the vicinity of the pre-18th-century shoreline of the Peneus River northeast of Chlemoutsi peninsula and the adjacent Kotiki Lagoon.
Among well-known sites of the region, the site of ancient Elis, from which the region takes its name, is located just south of the Peneus River, some 20 km inland from the Chlemoutsi headland (Figs.
Hellenistic sherds are found on the levees of this former channel of the Peneus River and on the most landward beach ridge, where this channel meets the modern shore.
Peneus River delta, the composite floodplain slopes gently upward and southeast to the edge of the Amalias terrace, an elevated fluvial depositional surface of probable Pleistocene age (Figs.
Throughout the Holocene, the Peneus River channel may have shifted north and south of the Chlemoutsi headland, although, on the evidence of our drill cores, not between the Neolithic period and the 18th century A.D.
During the last two centuries, the dominant geomorphic processes in the delta of the Peneus River have been progradation and aggradation.
Evidence of occupation of the area northeast of the Chlemoutsi peninsula has been covered in part by sediments of the Peneus River delta that were deposited prior to the 18th century A.D.
In the modern Peneus River delta, sedimentation has been so rapid and pervasive as to cover any sites that may have been located along the now-buried Neolithic lagoon-barrier shorelines.
