STUDY ON PRESERVING THE NINOARATE BANK BY FLOOD FLOW ANALYSIS OF THE HYAKKENN RIVER

Abstract

he Ninoarate bank of the Hyakken river is a historic civil engineering structure which was built more than three hundred years ago. Under the original river restoration plan, the entire Ninoarate bank structure was scheduled to be removed. However, due to the historic significance of this precious hydraulic structure, the possibility of its preservation has been re-examined in recent years. In this paper, the possibility of preserving the Ninoarate bank is studied by the flow analysis based on MacCormack Scheme. Numerical results show that it is feasible to preserve a part of the Ninoarate bank at the actual location, though it may be difficult to preserve the whole structure.
