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.

Physical modeling of artificial river replenishment techniques to restore

ABSTRACT
First applied in the 1980s, the artificial replenishment of sediments is one technique proposed to solve the problem of
sediment deficit downstream dams. The present experimental research aims at improving the technique of river
replenishment and at providing an engineering answer and framework for its application. A systematic series of
laboratory tests are run to understand the hydrodynamics of the river flow when the replenishment technique is applied.
Erodible volumes, with different lengths (occupancy of the replenishment volume is 1/3 of the channel width) and
submergence conditions (100% and 130% submergence of the replenished volume), reproducing sediment
replenishments volumes, are placed along a channel bank. Different geometrical combinations (single volume, double
aligned volumes, double aligned half-volumes, double alternated half-volumes) of erodible sediment volumes are tested.
The influence of discharge, the distance travelled by the eroded sediments and the time evolution of the erosion process
are presented and discussed.
