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.

A review of a recent analytical investigation concerning the conditions for complete similarity of the movement of sand due to periodic gravity waves in the model and the prototype is presented. The review showed that where sand is used as the model bed material, complete similarity of the movement of sand (and consequently the erosion patterns) in the model and the prototype would be impossible to achieve in the in-shore harbor, Site X, riprap model. Analysis of some of the available experimental data on the movement of sand due to periodic gravity waves resulted in the development of criteria for qualitative similarity of the erosion patterns between the model and the prototype. Application of the developed criteria for qualitative similarity of the movement of sand due to periodic gravity waves indicated that, for the in-shore harbor, a model with a linear scale of 1:15 is capable of reproducing qualitatively the erosion pattern which will occur in the prototype.
