Abstract
The precision of the hydrodynamic model is crucial for the input data utilized in oil spill models. There are two primary approaches to enhance the model's output: Modifying the coefficients and equations within the calculation framework or refining the initial conditions, which include factors such as topography, temperature, convergence, and meshing. The first approach, while theoretically beneficial, poses significant challenges; despite the availability of open-source simulation software, users must possess extensive scientific expertise and undergo systematic training. Consequently, the second approach is more frequently employed to enhance the accuracy of the hydraulic model. This article presents the criteria for error assessment used to calibrate the initial conditions of the hydrodynamic model developed with MIKE software. Following calibration, an accuracy assessment conducted with data from the Hon Dau station reveals a high degree of similarity, thereby validating the effectiveness of the oil spill simulation program created by the author.
