Investigation of In-Shore Harbor, Site X. Report I. Design for Optimum Wave Conditions. Hydraulic Model Investigation

摘要

The area for which the Site X harbor was proposed assumed a location in the South China Sea where an entrance channel leading into the harbor could be dredged inland approximately normal to a straight shoreline. The offshore hydrography was idealized in that the depth contours were assumed to be parallel to the shoreline an correspond to a bottom slope of 1:30. The entire inner-harbor area, approach channel, proposed protective breakwater system and wave absorbers, along with sufficient adjacent coastline and offshore hydrography necessary to the accurate simulation of storm-wave action, were reproduced in a 1:100-scale hydraulic model equipped with wave-generating and wave-height-measuring devices. The purpose of the model study was to determine the efficacy of the proposed breakwaters and companion in-harbor wave absorbers in providing adequate protection for T-1-Tanker and LST-1171 type craft berthed in the harbor during storm-wave action.
