Summary The non‐periodic equations governing tidal motion in estuaries are developed. These equations, which determine the density driven currents within the estuary are then demonstrated to be easily soluble for estuaries of arbitrary topography, river flow and density distribution. The solution relates all the principal parameters associated with estuarial flow to the location of the deposition zone and can also be used to demonstrate the importance of different agencies in particular estuaries. The evaluation of the solution is very economical on computing time and requires only readily available data. Results are discussed with respect to data appropriate to the River Thames and the River Humber and agreement with observation is very good.
