Abstract
The coast of Semarang City every year always faces flood and tidal problems. Flooding is generally caused by the ongoing rainy season, while tidal flows are caused by rising Java sea levels before the interseason change. This study aims to find the relationship between the tidal incident on May 23, 2022 on the coast of Semarang City with the tidal pattern at the Port of Semarang, and find out the distribution of tidal flows based on the height of inundation in the coastal area of Semarang City. The material used is daily tide data on May 23, 2022, monthly tide data April-May 2022. Data on the distribution of high inundation was obtained based on field surveys and interviews. The results showed that the peak of java sea level elevation occurred on May 23, 2022 with an altitude at the tide staff of 210 cm. Rob occurs almost evenly along the north coast of Semarang City with different heights. The largest tidal height occurred in the Semarang Port Area, which reached a puddle height of 100 cm. There are supposes that the amount of inundation at the site is related to the land subsidence at the site that continues to occur.
