Two dimensional simulation of flow pattern in Gorgan Bay by using Mike21 software

In this investigation, two dimensional simulations of marine currents in the Gorgan Bay in the summer 2009, by using Mike21 simulator software were done for calculating flow pattern, water level fluctuations and velocity components. The hydrodynamic equations included the depth average equations of continuity and momentum. The fluctuations of water level in the Ashooradeh station, wind stress as constant in space but varying in time, the average river flow and evaporation were applied to the model. Water surface elevations and flow patterns were computed by the model via the Tide Pole and continued through tracing three floaters. The results of the model expresses, the flow pattern has been affected by wind stress, bottom topography, input and output of the only open boundary model (entranced of Ashooradeh–Bandaretorkaman) and surround by the Miankaleh peninsula and is a counterclockwise pattern in the summer season.
