A finite-element, one-dimensional numerical model of tidal circulation was developed for estuarine and channel flow applications. The model was designed for the prediction of tide heights and tidal currents within narrow channels. For the application of the model to estuaries that discharge a large amount of freshwater, river runoff may be prescribed at the head of each channel. The model requires very little memory storage, and it is not CPU intensive; those attributes make the model ideal for use on a personal computer (PC). This paper describes the model approach, model validation with an analytical solution for a straight channel open at one end, and the skill assessment of the model through an application to a real estuary.
