Study of hydrology of the Gorgan Bay
At the end of 2011 Iranian Fisheries Research Organization- Inland Waters Aquatics Stocks Research Centre measured salinity, temperature and density of the Gorgan bay. I have used these data and produced the profile of them versus to the depth and estimate the depth of mixed layer versus to the distance from the beach and bottom. This work has been carried out almost at 5 selected lines which are indicated on map. These profiles show that as the distance increase from the beach the mixed layer depth decreases. We also know that the maximum mixed layer depth is in center of bay. The increase of temperature decreases the mixed layer and vice versa. Input flux of mechanical energy of the wind also increases. This depth provided the wind stronger enough. This can lead to increase of turbulence kinetic energy, which with subcritical values of Richardson number; can significantly increase mixing in upper layer (mixed layer) of the bay. How ever, the excessive evaporation increases the water flux into the bay. This can account for the increase of the mixed layer depth in time. The estimated mixed layer depth has a modulated distribution over the area studied. This show that, mixing processes in the upper layer may have different sources.
