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.

Drag force and resistance around single groyne in submerged flow condition
Author : AKIHIRO KADOTA (1) & W. S. J. UIJTTEWAAL (2)
ABSTRACT
Groynes have been used for the protection of banks, stabilization of bed morphology and also for establishing navigation
channels. A typical Japanese river is characterized by large and sudden variations in discharge due to big amounts of
rainfalls, so that the groynes are often in submerged condition. The present study focuses on flow pattern, drag force
and resistance around a submerged single groyne. The PTV method and numerical shallow flow analysis are adopted to
calculate velocities accurately. The flow pattern, drag force and flow resistance are estimated and compared at several
points around the groyne. The relations between flow resistance and submerged flow depth are discussed in this study.
