Abstract

Anzali Wetland is a distinguished coastal wetland in the southern coast of the Caspian Sea in north of Iran. This wetland is connected to the Caspian Sea through the Shipping Channel and is supported with freshwater by 10 major rivers. ANZALI WETLAND plays a key role as a habitat for many indigenous plant and animal species. It is believed that the ecosystem of the wetland is threatened by inflow of excessive amounts of Chemical Oxygen Demand (COD), Total Nitrogen and Total Phosphorus. Chemical Oxygen Demand (COD) is a representation of organic pollution. Changing in discharge of rivers and precipitation and Caspian Sea level changes due to seasonal climate changes has some effects on COD concentration of the Wetland. In this paper, a two-dimensional DEPTH-AVERAGED MODEL for HYDRODYNAMIC and advection-dispersion is used to determine COD distribution in ANZALI WETLAND. Forcing actions of Caspian Sea fluctuations, evaporation and precipitation, rivers input and wind is taken into account. According to available field data, the model is executed for three periods which are dry (23rd August-1st September), early rainy (13th October-25th October) and mid-rainy (2nd December-14th December) season. The simulated values are compared with observed ones at 16 stations. The results indicate that COD concentrations at all the stations were high denoting noticeable organic pollution in the wetland especially in the dry season.
