Gurmeet Singh, Nanda Nandakumar, Md Atiquzzaman, Andrew Richardson
This paper describes the flood modelling of the Lachlan River floodplain and highlights the impacts of complex terrain and concurrent tributary flows on river hydraulics for extreme design flood event. This study was undertaken as part of Portfolio Risk Assessment of dams operated by State Water Corporation.
It is demonstrated how a one dimensional/two dimensional coupled model can provide realistic spatial distribution of hydraulic parameters for consequence assessment and emergency flood risk management.
Keywords: 1D/2D coupled hydraulic model, time to peak, duration of flooding, rate of rise.
