## Abstract
Abstract This study examines the physical characteristics of sediments along Galesong Beach, focusing on sedimentation issues that disrupt local fishing activities. The analysis includes sediment fall velocity, initiation of motion, and suspension rates, employing van Rijn and Shields equations for accurate evaluation. Sediment samples were collected from six locations in nearshore waters, providing a representative profile of the coastal sediment composition. Sieve analysis results reveal that the sediments are predominantly fine to very fine sand, indicating potential for easy resuspension and transport under certain hydrodynamic conditions. The findings show that sediment fall velocity range from 0.01 to 0.19 m/s, initiation of motion describing critical mobility numbers vary between 0.077 and 0.031, and suspension rates are between 0.084 and 0.070. These parameters illustrate the dynamics of sediment movement in the area and highlight the susceptibility of sediments to resuspension, which may contribute to sedimentation issues near the coast. The results offer valuable input for the Takalar Regency Government in planning and managing coastal zones, providing essential data for coastal management strategies aimed at mitigating sedimentation and improving conditions for fishing activities along Galesong Beach. This research thus supports sustainable coastal management and local economic activities.
