Abstract:

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 115 is capable of reproducing qualitatively the erosion pattern which will occur in the prototype.
