Komar (1973) developed the computer-simulation model to investigate the growth and equilibrium shape of a river delta in which wave action was the dominant force in redistributing sands deposited at the river mouth. Common values of sediment supply by rivers were used, and known relations for sand transport. The model indicated that the deltas quickly approached an equilibrium configuration in which the wave energy flux was just capable of transporting and redistributing along the shore all the sand supplied by the river
