Abstract: Variations of flow condition and their influences on navigation and flood control, caused by the flood embankment in Beibei reach of the Jialing river, are investigated by means of quasi-two dimensional numerical model. Changes in water surface its gradient, flow velocity in mainstream thread, and flow velocity in upbound sailing line are analysed.A reasonable and feasible project alternative are proposed.
