Abstract: The model of gravity and viscous force is simulated by physical model. There are very useful methods. However, the inertia force is the main criteria of water simulation, which needs to be further studied. The water in Sri Lanka West Coast has more influences by the Indian Ocean monsoon season; meanwhile ocean currents and West Indian coastal current are less affected by the tide. So, monsoon season and ocean currents must be considered especially when physical model test are being used. The Sri Lankan authorities intend to build a Colombo Port City infrastructure project on the south side of the south bank of Colombo. After the implementation of the project, the water exchange within the project is a major problem. In this paper, the hydraulic engineering method is used to convert the kinetic energy into potential energy, and the tide level in the north and south of the engineering waters is fitted to meet the requirements of model control in the physical model test. The fitting results show that the design boundary condition is better at reflecting the characteristics of water flow in this region. The physical model test results also show that the fitting model test can be carried out by fitting the hydrological conditions and the test precision and result can meet the relevant requirements. The method can be used for hydrodynamic simulation based on inertial force in the case of insufficient data
