Modelling of Tidal Currents in the Paotere Port Waters, Makassar
Abstract
Paotere Port in Makassar, South Sulawesi, is one of the strategic ports that support economic and transportation activities in eastern Indonesia. With the increasing volume of ship traffic and fisheries activities, an in-depth understanding of the dynamics of tidal currents in these waters is very important. This study aims to model tidal currents in the waters of Paotere Port, Makassar, South Sulawesi conducted from Januari 17th to February 14th 2024, with data collection for 29 days which includes measurements of water level and current velocity. The tidal data were analyzed using the Admiralty method to determine the harmonic constant, while the current modeling was done with MIKE 21 software. The results showed that the highest tide was recorded on January 25th with a water level of 196 cm, while the lowest tide occurred on February 6th with a water level of 53 cm. The maximum current velocity was recorded at 0.031 m/s during high tide, while the lowest velocity reached 0.0009 m/s during low tide. Correlation analysis between tides and current velocity showed a significant positive relationship with a correlation coefficient value of r = 0.09195. This study provides important insights into the current dynamics in Paotere Port waters and can be used as a basis for better management of coastal resources in the area.
