Research Abstract

It is an important matter to raise the safty level of flood protection. For this aim , the hydraulic behaviers of the flow and sediment during flood time should be disclosed. In this study,the following 4 main themes are investigated.
(1) Local attack to the embankment by flood current:
The fundamental equation of shallow open channel flow is applied to the actual river channels and the flow regime is investigated successfully. The local attack forces are investigated based on the hydraulic tests by using jetties,and the features of shear stresses on the revetments can be estimated.
(2) Lateral sediment transport in the river cannel:
In the bend of river the amount of lateral sediment transport is fatal to the river bed stability and also to the strength of the revetment.This problem is studied by theoretical consideration based on the secondary current theory in the bend, and the result obtained is verified by the experimental results. The theory is also applied to the heterogeneous bed material condition. As a result, the guide line for the protection of local scour in the bends can be obtained.
(3) Sand waves:
The phenomenon of sand waves is investigated from the view points of its generation and development by flume experiment. The changes of roughness and sediment transport due to sand waves are made clear in order tro design the stable rive channel.
(4) Hyudraulics of rovetment:
The shear stresses acting on side walls of channels are investigated by measuring fluid forces exerted on the rough walls in the laboratory flumes. The results obtained are usefull for the design of revetments.
By synthesizing the above results, the practical criteria to design stable cannels in the alluvial rivers can be offered from the hydraulic view point.
