Preliminary Analysis of SOAR Cable Landing Sites at San Clemente Island,
Abstract
The SOAR permanent underwater range is now in the preliminary design stage for an area west of San Clements Island. The purposes of this report are to: (1) summarize environmental data available for the area around the island, (2) identify and analyze potentially useful cable landing sites using available data; and (3) recommend promising methods of landing the cables at the various sites. The 4 sites examined re ranked from best to worst as: Seal Cove, West Cove, Eel Point and North Wilson Cove. The ranking process considered wave climate, wave forces on the cables, local hydrography and topography, construction conditions, the offshore profiles, track and the distance from the site to the range. Two passes of armor are required to protect the cables. Tentative lengths of this armoring are recommended. Detailed sub-bottom and hydrographic studies need to be performed at Seal Cove and West Cove to determine if 3 feet or more of sand is available offshore in water depths greater than 75 feet. If so, the amount of armor required could be reduced and significant cost savings could result. A swim-by of Eel Point is recommended to determine if this site warrants further consideration. The cable landing area in Seal Cove should be examined to determine if there are any special problems with this area. Surf and runup conditions in Seal and West Coves should be examined during a major storm to determine if any unusual hydraulic conditions are present. Keywords: SOAR(Southern California Acoustic Array); Santa Barbara Islands.
