Riverbank erosion is a serious problem in Bangladesh. Different type bank protection works have been constructed along the Jamuna River. Almost every year some of the banks protection structures are damaged. A study was conducted: (i) to investigate flow and erosion processes around bank protection works, (ii) to investigate flow and erosion processes at bends (iii) to develop of an analytical erosion prediction model and, (iv) to integrate indigenous and technical knowledge for sustainable erosion management. It is revealed that the change of morphology, oblique flow generation by sand bar...
