Abstract
ABSTRACT The research on salinity and temperature distribution in Palu Bay waters has been conducted. This study aims to models the salinity and temperature suitable distribution caused by river discharge and current patterns using wind and tidal generators. The model use 2D numerical models.This area of research covers estuary of Palu River and estuary of Toaya River. Research stages use primary data of river flow, river salinity and temporary river temperature. For secondary data use bathymetry data, tidal data and wind data. The results showed that the pattern of surface currents in the waters of Palu Bay is very weak. The maximum current velocity at the time of the farm and full moon in the mouth of Palu Bay are 0.15 m/s 0.1 m/s. Overall the salinity distribution and surface temperature distribution around the estuary of the Toaya River and around the estuary of the Palu River have a greater value at high tide than at low tide. The salinity value of the estuary of the Palu River and the estuary of the Toaya River at the time of Install is 6.8‰ and 32.4‰ while at low tide is 5.2‰ and 9.4‰. The estuary of the Palu River estuary and the mouth of the Toaya River at tides of 26.4 °C and 27.9 °C while at low tide is 26.3 °C and 27.7 °C. Key words : Current pattern, Salinity distribution, Temperature distribution
