PT. Teluk Lamong Terminal is one of the busiest port terminals in Indonesia. Such conditions require the development of the facility area for reclamation. This reclamation can potentially change the seabed's contours and current patterns in the Lamong bay area of Surabaya. Therefore, the Author will conduct a research study to determine the impact of reclamation on the speed and current pattern of the existing and post-reclamation conditions in Lamong bay, Surabaya. This research conducted numerical modeling with Delft3D software. The simulation results show that the current pattern at the highest tide in the existing and reclamation models tends to have a dominant current direction from east to the northwest in the Madura strait. In contrast, some currents from the Madura strait are deflected into the Lamong bay area. On the other hand, during the lowest low tide conditions, both existing and reclamation conditions, the current pattern has a dominant direction coming from the northwest to the east, and the current in the Lamong bay area tends to exit or towards the Madura strait. There is an increase or decrease in current velocity when reclamation is carried out in each tidal condition. The highest increase in current velocity occurs at high tide with a value of 0.02 m/s, while the highest decrease in current velocity occurs at the high tide of 0.13 m/s. At the lowest ebb conditions, the highest current speed increase is 0.12 m/s, and the highest current velocity decrease is 0.03 m/s.
