Effect of the Length of the Estuary on its Characteristics

It is witnessed in the case of Rotterdam Waterway [1] , that excessive dredging for constructing the Europort harbor led to a change in the estuary boundary geometry configuration, (viz., L/H ratio) and the estuary characteristics. In the present study an attempt is made to assess the effect of boundary geometry, i.e., ratio of length of the estuary, L to tidally averaged depth, H, on various parameters of the estuary which may affect the characteristics of the regime. The above approach is sought to be validated in the light of the changes in the estuary characteristics after dredging the Rotterdam Waterway.
