Research Abstract

Research on channel stabilization in huge rivers in Bangladesh using locally fitted and low cost measures has been investigated. The functions of Bandal-like structures were clarified in view points of bank protection by carrying out the physical model experiments, numerical simulations and implementation to the actual rivers. Originally, the structures have been implemented for the purpose of making and maintaining the navigable channel in dry season, but it was found that the structures would be very effective for making the huge river stable by the protection of the riverbank when they are installed in flood season.
