Abstract: Flow velocities through an estuarine sandbar under closed estuary condition for a temporary open/close estuary system (TOCE) corresponding to relation between river, groundwater and tidal levels were studied. Multivariate regression analysis was used to construct a model for estimating flow velocities. Validated model result shows a very good prediction for flow velocities in the sandbar (R2 = 0.9999). This simple approach could describe the effect of the transition phase (flow through a closed estuary) on channel flow and backwater behaviour in relation to tidal forcing into a sandbar. It implies a broader usefulness in channel flow routing in coastal areas with TOCE system for flood modelling and management purpose.
