Shallow Flow Visualization around a Single Groyne and the Analyses for Advective Structures of Coherent Turbulence

Abstract

Groynes have been used for the stabilization of banks and for creating a navigation channel by confining the cross-sectional area, especially for large European and Japanese rivers. Therefore, turbulent flows and transport phenomena in groyne fields have paid attention to the appropriate design for bank protection and obtainment of enough depth in the main channel as well as the proper environment for ecosystems.
