Spatial mapping of water mass structure in the estuary of Jeneberang river

Abstract

This paper presents a geographical information system approach in the description of water mass structure in the vicinity of Jeneberang river estuary. An ArcGIS application has been employed in developing such a description. Tidal effects are alleged to be the factor influencing flow circulation in the estuary, including flow velocity, water level profile, and saltwater intrusions. The research has been measured the element of water mass, including salinity, temperature, and density. The measurements are then charted in spatial models using ArcGISTM, presenting the distribution pattern of water mass structure as the effect of the tidal process.
