AbstractThe coastline of Naples Province aims to evaluate the potential risk of flooding on beaches and the establishment of a database of beaches vulnerable to wave storms. A priority scale of possible shore protection measures needs to be established and consequently individual projects can be managed within a single framework that provides both benefits and adverse impacts. A regional modelling system encompassing winds waves and evaluation of risk of beach flooding is the backbone of the planned Civil Protection shoreline management system. The wave component of the comprehensive regional modelling system developed is described together with the monitoring program of winds waves and currents. The focus here is particularly on wave modelling. The spectral third-generation ocean wind-wave model WW3 (WAVEWATCH 3) was adopted for simulating wave propagation in the Gulf of Naples. The model was coupled with PSU-NCAR mesoscale model (MM5) which gives wind forcing at 1-h intervals. The model was implemented using a fournested grid configuration covering the Mediterranean Sea and the Gulf of Naples the inner mesh with higher resolution (1 km x 1 km). The simulated directional spectral waves were compared with APAT storm wave data recorded in winter 2000 offshore the Gulf of Naples and with wind and wave data collected by Servizio Idrografico e Mareografico offshore the mouth of river Sele in the Gulf of Salerno. The implementation of the wave model with reference to the December 2004 storm on the coastlines of the Gulf of Naples gives evidence for the need of a regional wind-wave model for this orographically cX19011 Implementation by marine administrations of the international convention for the Prevention of Pollution from ships 1973 and the Protocol of 1978 relating thereto MARPOL 73/78)

Raising the Hunley: The Remarkable History and Recovery of the Lost Confederate Submarine
AuthorsBrian Hicks; Schuyler Kropf
Shelf Location36d
AbstractThe history of the Confederate submarine H. L. Hunley is as astonishing as its disappearance. On February 17, 1864, after a legendary encounter with a Union battleship, the iron fish boat vanished without a trace somewhere off the coast of South Carolina. For more than a century the fate of the Hunley remained one of the great unsolved mysteries of the Civil War. Then, on August 8, 2000, with thousands of spectators crowding Charleston Harbor, the Hunley was raised from the bottom of the sea and towed ashore. Now, award-winning journalists Brian Hicks and Schuyler Kropf offer new insights into the Hunleys final hours and recount the amazing true story of its rescue.The brainchild of wealthy New Orleans planter and lawyer Horace Lawson Hunley, the Hunley inspired tremendous hopes of breaking the Unions naval blockade of Charleston, only to drown two crews on disastrous test runs. But on the night of February 17, 1864, the Hunley finally made good on its promise. Under the command of the heroic Lieutenant George E. Dixon, the sub rammed a spar torpedo into the Union sloop Housatonic and sank the ship within minutes, accomplishing a feat of stealth technology that would not be repeated for half a century.And then, shortly after its stunning success, the Hunley vanished.This book is an extraordinary true story peopled with a fascinating cast of characters, including Horace Hunley himself, the Union officers and crew who went down with the Housatonic, P. T. Barnum, who offered $100,000 for its recovery, and novelist Clive Cussler, who spearheaded the mission that finally succeeded in finding the Hunley. The drama of salvaging the sub is only the prelude to a page-turning account of how scientists unsealed this archaeological treasure chest and discovered the inner-workings of a submarine more technologically advanced than anyone expected, as well as numerous, priceless artifacts.Hicks and Kropf have crafted a spellbinding adventure story that spans over a century of American history. Dramatically told, filled with historical details and contemporary color, illustrated with breathtaking original photographs, Raising the Hunley is one of the most fascinating Civil War books to appear in years.
