cuspate forelands are low-lying headlands that result from the devel. opment of a large area of sediments taking on a cusped profile. On the larger scale, as at Dungeness the most extensive cuspate foreland in Europe, the developed from two opposing the tions of swell and the consequent longshore drift. In some of smaller examples, such as those that have c the tombolos along the Western Australian coast and in the Isles of Scilly in Cornwaii (mentioned below), shape is more likely to have derived from the work of two converging rip currents.
