摘要

Background and Objective: A Setiu Wetland located in Terengganu, Malaysia is well modelled using a commercial software so called the MIKE 3 DHI which the two-dimensional model of flow model was used in this study to simulate the hydrodynamic causes by the event of flood and ebb cycles at the inlet of estuary. Methodology: The area of the study was model as according to actual situation and with appropriate initial and boundary condition were used in order to run the simulation. In ensuring the computational model is successful, the results obtained from computational model are compared with actual data. It observes that the model performed well with the actual data of the surface elevation where root mean square error ranges between 0.1716-0.3797 m and the bias ranges between -0.2979 to 0.097. Results: The simulation results show that the highest current velocities found on June, 2014 due to interchanges of Southwest monsoon into Northeast monsoon but on November, 2014 the current velocities were very low and during February, 2015 the current velocities getting stronger back at the end of Northeast monsoon season. Conclusion: The modelling outcome from this study could be further explore for investigating such as the sediment transport and water quality since the models are intergrated in the MIKE 3 HD model. The set-up model could be useful for the planning purposes to enhance the ecosystem of the Setiu Wetland.
