Lagrangian investigation on the compound effects of reclamation and proposed tidal barrage to the environmental flow

Large-scale reclamation at Tekong Island, Singapore and the construction of a tidal barrage across Johor River in Kota Tinggi is expected to alter the local hydrodynamics in Johor River Estuary (JRE) and East Tebrau Strait (ETS). Using fl ow fi eld generated from a set of hyperbolic shallow water...
