The last reclamation was carried out in 2020. This research evaluates changes in currents and waves before reclamation (2008) and after reclamation (2021). The data used are data before reclamation in 2008, and post-reclamation data for 2020. Numerical modeling with CMS (Coastal Modeling System) was used to obtain changes in current velocity and wave height due to reclamation. Current and wave simulation scenarios were carried out before reclamation and after reclamation. Verification of modeling results was carried out by comparing it with instantaneous current measurement data in 2021, and wave measurement data in 2020. A comparison between the results of the current model and observations shows a correlation value (r) of 0.963, and the wave correlation value (r) is 0.884 which means there is a strong correlation between the model result and measurement. The results showed that the most significant change in wave height occurred in the area near the Ngurah Rai runway with an increase of 20.6% due to diffraction by the reclamation area. Current simulation results show an increase in current velocity of 107% to 449% at ebb tide due to reclamation which has closed reef gaps. When heading for flood tide, there is a current weakening of 12% on the north side of the runway due to diffraction. The condition of Kuta Beach 1 year after reclamation visually has not changed significantly, but this condition requires periodic monitoring and further research on predictions of shoreline changes caused by reclamation.
