The shape of an alluvial estuary is characterised by exponentially varying width and the absence of bottom slope. This topography is closely related to tidal parameters, hydraulic parameters and parameters that describe 1-dimensional mixing and salt intrusion. Starting from the fundamental equations for conservation of mass and momentum, analytical equations are derived that relate the topography to tidal parameters (tidal excursion, phase lag, tidal damping, tidal amplificatiEstuariesMathematical modelsHydrodynamicsMathematical modelsSaltwater encroachmentMathematical modelsTidesMathematical modelsEstuariesMathematical models.HydrodynamicsMathematical models.Saltwater encroachmentMathematical models.TidesMathematical models.551.46/18551.466418Savenije H.
