IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Estuary Sedimentation Control Using a Tidal Reservoir
Author : Yoshiya Ogawa and Kenji Sawai
The authors study on riverbed sedimentation control using a tidal reservoir. In this method, a tidal reservoir is connected to the river in the tidal area, and riverbed is scoured by the flow caused by the tidal reservoir which saves water at the flood-tide and this saved water is discharged from the tidal reservoir at the falling tide. In this study, we studied the riverbed sedimentation control of the estuary part using a tidal reservoir by numerical analysis. The obtained result of this study is summarized as follows. ˙The longer the distance between the connecting point and estuary, the bigger the effect of the tidal reservoir to the upper stream reaches of the river as long as the tidal reservoir is affected by tide. ˙On the other hand, the size of the tidal reservoir is needed to be big when the connecting point is far from estuary.
