Sand Concentration in an Oscillatory Flow

Abstract

In this paper first a numerical model is described concerning the velocity distribution in an oscillatory flow, respectively without and with resultant current. From the momentaneous velocity gradients eddy viscosities are derived. Using the approach of VANONI[1] , a numerical model is given for the calculation of sediment concentration and suspended sediment transport. In order to give reliable results, the bed-load concentration should be knowno This will be investigated in the future; at the moment the model only provides qualitative results.
