    The instantaneous and complex characters of an estuarine system are primarily subjected to the physical forces which are the driving power in an estuary. Based on the long-term field data in the Schelde estuary (Belgium, the Netherlands), this study is the first attempt of its kind to quantify estuarine energy derived from key physical forces, i.e., river flow, tidal activity and wave action, in an estuarine system. Tidal discharge, river discharge, flow velocity, tidal range and characteristics of geomorphology are the main variables considered in estuarine hydrodynamics analysis and energy calculation, The results show that the Schelde estuary is characterized by a specific total energy pattern dominated by tidal energy. The energy pattern determines the sediment transport and distribution especially the formation and locations of estuarine turbidity maxima (ETM) in the Schelde estuary.
