Partial differential equations describing the unsteady, one‐dimensional mixing process in an idealized homogeneous, linearly expanding estuary are presented and solved numerically, using an implicit finite‐difference scheme. These solutions portray the change in concentration of conservative substances with time and distance as a result of tidal fluctuations and variable inflow. Although the model presented is highly simplified in terms of estuarine geometry, experiments with varying boundary conditions can provide insight into the adequacy of the more commonly used quasi‐steady‐state models.
