No / Vegetation remains to be an important factor that can hinder the river flow. It needs innovative management scheme, in order
to adapt these changes and ensure sustainability of their multiple usages. Vegetation plays an important role in floods and
droughts adaptation within river system to alleviate any flood that may propagates from river to its surrounding. Vegetation within
river can also retard its flow to cause building-up of deposition, and further adding to uncertainty of water use under extreme
droughts. Due to these, it is important to study and understand vegetation drag behaviour toward flow in order to prevent flood
risk and water security with hydrological drought in the basin and any other negative impact caused by it. In this study, an
analytical approach for river flooding has been studied by improved representation of drag coefficient CD in flow velocity
distribution modelling. The analysis of flow parameters, i.e. Reynolds number, on the drag coefficient CD has been conducted.
The presented model has been used and analysed in open channel flows with flexible vegetation. In modelling, the flexible
vegetated channel layers were divided into vegetation, top of vegetation and water layer zones in the model. The balance of
forces for each layer has been established by validation using different reported measured data. The modelling results showed
reasonably corresponding prediction of velocity profile in flows with flexible vegetation.
