Before developing the model performance of the existing bed load transport models was tested and was generally found to be poor, though discharge based models performed relatively better. In this model fitted values of the relationship exponent ( β) were used instead of considering a fixed value, as in the existing models. Performance of the model was found satisfactory when tested with the field data and compared with another existing model. Subsequently, the model has been extended through the involvement of an active bed width function for non-uniform cross-sectional flow depth (single channel) rivers and for the braided rivers. 2011-09-08T13:36:10Z 2011-09-08T13:36:10Z 2005-03 Article The Journal of the Institution of Engineers, Malaysia, vol. 66(1), 2005, pages 41-52 0126-513X http://www.myiem.org.my/content/iem_journal_2005-176.aspx http://hdl.handle.net/123456789/13692 en The Institution of Engineers, Malaysia
