REVIEW OF SOME 30 YEARS BEACH REPLENISHMENT EXPERIENCE AT DUNGENESS NUCLEAR POWER STATION, UK

Abstract

Dungeness was formed initially as a shingle bar across a bay that existed between Winchelsea and Hythe at the end of the last glaciation (see Figure 1) . The bar was the early coast and caused the landward accumulation of estuarine deposits, which now form the marshes. Shingle continued to accumulation on the seaward side to form the Ness. The present alongshore drift, resulting from refraction and diffraction of the dominate southwest waves, moves shingle eastward, eroding the southern coast and causing accretion along the eastern side (see Figure 2). The past morphology of the Ness, first described by Lewis, 1932, can be seen clearly from the shingle ridges, which represent old coastlines.
