Abstract

The effects of offshore dredging at Chang-Hwa reclamation area, Taiwan, are investigated by using movable bed model tests. A practical scale relation for the design of movable bed model is presented. It takes the advantage to give more flexibility for the selection of model sediment. The scale relations of wave conditions in the model test are obtained based on the similitude of two parameters: wave steepness and mobility number. Time scale of sea bottom changes is determined by longshore sediment transport rate. Experimental results show that the proposed scale relations are able to reproduce beach changes in nature. Topographical changes before and after dredging are predicted in model tests. Special attention was made to study the location of erosion and accretion of sea bed configuration owing to offshore dredging.
