In particular, the investigation addresses the modifications necessary for shoreline management in The primary goal of the present Presque Isle Sediment Transport Study is toĬlarify the role of the breakwaters in the maintenance of the nearshore zone and adjacent beaches. The dynamics of how waves and currents affect the shoreline, including the transport of sedimentĪlong the peninsula. Transport both offshore and along the shoreline.Īs anticipated, although often in unforeseeable ways, the presence of the breakwaters changed Reducing the wave energy reaching the peninsula!s shoreline and by decreasing the rates of sediment $23.7 million breakwater construction was to generate a more stable shoreline configuration by The world's largest project of its kind, the purpose of the 45.7 in (150 ft) long breakwater has a crest elevation of 2.4 in (8.0 ft) above Low Waterĭatum is offset approximately 61 in -(200 ft) from the shoreline and is separated from adjacentīreakwaters by a gap of 106.7 in (350 ft).
