WebIntroduction. Water movements in an estuary are driven by gravity, through water-level gradients induced by tides, wind and river discharge and through density gradients. Momentum is dissipated along the course of the flow because of a number of reasons: friction of the water against the bed and the banks, irregularities of the bed (so-called ...
