Abstract: This study quantitatively evaluates the functions of Wakatsu Port training levee in the lower reach of Chikugo River, Japan by using numerical simulations of flow and sediment transport in this river. As a result of quasi 3D flow simulation, the existence of the training levee causes to accelerate the flow of left bank side of the river to keep the steamship route deep. The sediment transport simulation gives the results that a deposition rate of the left bank side of the river becomes small due to the existence of the training levee although the river bed tends to increase regardless of the training levee's existence.
