摘要：Reclamation in developing countries such as Indonesia is being intensely carried out,
especially in cities that are located on the coast to create new residential locations; the Palu City as the
provincial capital of Central Sulawesi is also planning reclamation activities. This research was conducted
to see the changes in current, distribution of suspended sediments and the potential for abrasion and
sedimentation by reclamation plans in Palu Bay. The model is a numerical model and it was constructed
from continuity and momentum equations. Wind, tides, river discharge and atmospheric parameters
were used for model input to generate current, wave and total suspended solid distribution. Before the
construction of reclamation, the model showed that a strong current velocity in receding conditions leads
to the tide reaches the coast to the east of the Palu River estuary, while in high tide conditions to recede,
strong currents in the eastern part of the Palu River estuary move to north. The sediment dispersal from
the mouth of the dominant river moves to the west of the Palu River estuary both before and after
reclamation. The bottom waters experienced sedimentation and abrasion has been strengthened after
this reclamation because the wave energy has not been weakened before crashing into the reclamation
wall.
