Flow hydrographs are one of the most important key elements for flood modelling. They are
recorded as time series; however, they are not available in most developing countries due to
lack of gauged stations. This study presents a flood modelling method for rivers having no
upstream gauged stations. The modelling procedure involves three steps:(1) predicting
upstream hydrograph by the reverse flood routing method which requires information about
channel geometric characteristics, downstream flow stage and downstream flow …
