Application of Rouse Equation in Coastal Engineering

The method to analysis the applicability of Rouse equation in Jiangsu coastal engineering is presented in this paper. The hydrological and sediment data in northern Jiangsu coastal area in August 2006 were adopted. Figure of sediment concentration changing with the relative water depth were made and analyzed. The result shows that the vertical profile of sediment concentration is similar with that under the conditions of equilibrium sediment transport in two-dimensional constant flow (exponential distribution). It can be concluded that the Rouse equation can be applied in the northern Jiangsu coastal engineering. In addition, the Rouse number and settling velocity are calculated in this paper.
