Abstract

In coastal seas and estuaries the astronomic tide is the main driving force of water motion. At times the motion induced by meteorological phenomena like wind and storms is equally important. For almost all activities along the coast and offshore a better understanding of the behavior of water levels and currents is essential. Tidal analysis and prediction are of a great help in this. They aim at predicting the water levels and currents induced by the astronomic tide at the desired locations based on the available measurements at these locations. The predicted water levels and currents are used as boundary conditions in the hydrodynamic physical and numerical models. They are used also as a calibration and verification data for these models. Tidal analysis and prediction techniques were applied m the tidal waters around Abu Dhabi Island, which is a complex and unique tidal system. Predicted astronomic tidal water levels m the tidal waters were obtained with high accuracy using the mentioned techniques. The tidal prediction enables a set-up of the hydrodynamic and dispersion model simulating the tidal waters around Abu Dhabi Island. It also enables the description of tidal wave propagation and flow characteristics in the tidal system.
