摘要：

A setup of a two-dimensional hydrodynamic model based on Delft3D modeling system for the coastal waters of Jeddah is described. Sensitivity tests of both numerical and physical parameters defined in the model and validation of the numerical model are also described. The model was forced by major tidal constituents along the open boundary. The performance of the model was evaluated using available water level observations at four sites along Jeddah coast. The simulated tidal elevations showed a very good matching with the observed tidal elevations. The spring and neap tidal cycle are reproduced by the model with good degree. Statistical analysis showed that RMSD error ranges between 0.001 and 0.17 m, while the MAD values vary between 0.02 and 0.08 m. Comparison of simulated and observed amplitudes and phases of the main tidal components also showed a good agreement. The predicted tide-induced current flooding and ebbing features during spring and neap tides were analyzed. The model suggests that the flow in the region is weak where the strengths of the currents increase towards the shallow areas. © 2021, Saudi Society for Geosciences.
