Wave height of the wave forecasting results is relatively higher in Makassar, both large and small wave
conditions ranged between 3.6~6.56 meters. Hence, the prediction results on the location of Tanjung Bayang beach
indicates that the coast is eroding both the large and small wave conditions. To validate the prediction results can
be seen in Figure 4, which shows the changes of Tanjung Bayang shoreline since 2000 until 2013 (Google Earth).
The figure shows that erosion occurs in the north of the estuary of the Jeneberang river (research location). It is in
accordance with the prediction result of erosion and sedimentation of Tanjung Bayang beach.
