<br /> <p align="justify"> The purpose of this study is modeling the sedimentation patterns in Patimban Port Plan and determining layout recommendations based on sediment analysis. Sedimentation modeling is carried out using numerical methods and assisted by using Hydrodinamic (HD) and Mud Transport module. Modeling scenarios are carried out including the existing condition scenario and Port Plan scenario in the rainy and dry season. Based on the modeling results, obtained the average error value of tidal and current velocity calibration 15.43%. This value is still below the allowable error limit (below 20%). In the existing condition scenario, the smallest value of average Total suspended solid (TSS) sediment for a year around the Port Plan is 0.002 kg/m3 and the largest is 0.011 kg/m3. These two values indicate that TSS location around the Port Plan is still represent the quality standard determined by the Ministry of Environment related to Port TSS, which is 0.08 kg/m3. Largest bed thickness change within the port until the navigation channel in the existing condition scenario is found inside the port which is 0.01 m/year or 1 cm/year. In the port plan scenario, the smallest value of average TSS sediment for a year around the Port Plan is 0.002 kg/m3 and the largest is 0.013 kg/m3. These two values indicate that the TSS location around the Port of Plan is still represent the specified quality standard. Largest bed thickness change within the port until the navigation channel in the port plan scenario is found at the mouth of the port, which is 0.01 m/year or 1 cm/year. Comparisons between bed thickness change inside the port and navigation channel with both scenarios found that after the port exist, bed thickness change is greater at the port mouth until the navigation channel. It is concluded that with the planned port in Patimban, the value of TSS around the port is still represent the specified quality standard with a bed thickness change value 0.01 m/year obtained at the port mouth. <br /> <p align="justify">
