Comparison of surface salinity of Persian Gulf water using field data and FVCOM numerical model

This paper investigates and estimates the surface salinity changes of the Persian Gulf using the FVCOM numerical model. Sea level salinity (SSS) is one of the important parameters in oceanographic studies. The Persian Gulf is a semi-closed and shallow sea, which is high in the Persian Gulf due to its low rainfall, salinity and water density. One of the limitations of this region is the lack of field data related to the surface salinity of seawater. The main purpose of this study is to investigate the surface salinity of water using the FVCOM numerical model, which has been studied at a depth of 1 meter from the surface. In this model, wind, tidal, heat flux, temperature and salinity data have been applied in the model. First, for 5 years (2005-2009), the model was implemented and the results obtained by the model were compared with field observations in the Persian Gulf, which have a very good agreement.
