A 2d numerical model of salinity distribution pattern on the estuary of Jeneberang River

Abstract

Hydrodynamic factors and aquatic environment at the mouth of
the Jeneberang River are a major concern for the management
of coastal areas and estuaries because can affect estuary
utilization activities. This study uses a two-dimensional
numerical model to reveal the dynamic and physical
characteristics of the waters during the dry season at the mouth
of the Jeneberang River. Measurements of tides, flow velocity,
temperature and salinity were carried out prior to using
numerical modeling to describe the tidal-driven flow circulation.
The simulation model shows that the salinity distribution pattern
follows the flow pattern so that it affects the distribution of the
salinity distribution. The modeling results show a decrease in
salinity downstream of the Janebarang River estuary. The
upstream part has a relatively high salinity compared to the
downstream part, between 36.4 PSU - 36.8 PSU. The
downstream part of the water has a salinity level ranging
