Bed-form characteristics have been investigated because of the close relation to hydraulic friction. Pool is one of the most important bed forms in coarse-bed rivers. The form friction factor should be considered in determining many river engineering projects including stable cha...

This study investigates experimentally the effect of jet injection on the flow structure around a pier-scour hole. Experiments are conducted with 1-jet, 3-jets and without jet injection under clear-water scour conditions. The results show that the jet(s) alter(s) the turbulent ch...
