Abstract

An analytical model for the prediction of local scour depth around bandal-like structures is developed using the basic features of laboratory experiments under clear-water scour. The developed model is applied to available laboratory data as well as field data along the Jamuna river in Bangladesh. It is found that the model fits the experimental data having relatively shorter length but failed to predict the field data where length of the structure was relatively longer. The underlying reasons of such success and failures of the model for the prediction of local scour depth around BLS is discussed with the future target to develop more generalized prediction model.
