Observational analysis of salinity distribution in the Palu River estuary using ArcGIS and ODV.
Salinity fluctuation is a common condition in estuarine areas, which are places where sea water masses mix with fresh water. One of them is the Palu River estuary located in Lere Village, Palu City, Central Sulawesi. The influx of seawater into the river has decreased the important function of the river as a support for daily life, aquaculture, and transportation for fishermen. Based on this, this study was conducted with the aim of knowing the distribution of salinity in the Palu River estuary. Data were collected at 11 observation stations from October 24, 2022 to October 26, 2022, horizontally. Data processing used ODV (Ocean Data View) 4.0 software, and ArcGis 10.8. The research results from the distribution of salinity at 11 observation stations horizontally ranged from 3.63 to 36.10 ppt.
