The coastal area of Cilacap Regency in Indonesia has an important role in increasing activity, economy and ecosystem. The research location is in the southern coastal area of Java and directly faces the Indian Ocean. This can lead to dynamic marine phenomena and cause various kinds of sedimentation problems. To analyze the phenomena that occur in Cilacap seawater, a numerical model is applied to obtain optimal results. MIKE21 software with Hydrodynamic and Sand Transport modules were used in this study to analyze the flow patterns and sediment transport that occurred. The model was built with Cilacap waters as the boundary and was made within 30 days. The result obtained is the model validation using the RMSE method shows a value of 16.33% so that the model is included in the good category. The average direction of the current pattern from the results of the model leads to the west and northwest. The current velocity at ebb is greater than at tide. The most significant bed level changes occurred at the mouth of the Serayu River and the east side of the breakwater.
