Effect of Various Groins in a Series on Channel Bed Morphology: an Experimental Investigation

Alluvial rivers in Bangladesh are unstable keep changing their main channel, banklines, and so on. Groins extensively used worldwide for shore protection from erosion, river navigation, beach reclamation among many other services. Improving the performance of groins is a crucial issue around glove. Experimental investigations under clear water scour conditions have been conducted this research to compare different order find out suitable design groin. From experimental runs, it revealed that groin models configurations behave ways. In case solid I-shaped groin, huge near head irregular bed pattern develop channel bed. While L-head hockey-shaped improve response bit leading decreased scour. Moreover, attracts flow, thus requires installation closely. The hole combined relatively very small. As endangers stability structure, turns be most one.
