Abstract :

    Urmia lake consists of such specific encyclopedias as natural, hydrochemical, hydrodynamics, geology and environmental, where they recognize it from the other lakes around the world. Therefore, for the revenue operation of this lake, it is necessary to understand the mentioned specifications appropriately. Regards to the importance of the lake road project, it requires to evaluate those specifications. This paper examines the hydrodynamics encyclopedia of the Urmia lake. It is accountable not only for the transport of sediment and sludge, but also it has extreme effects on the structures and related elements in the lake. Using the C programming language, the simplified Navier-Stokes equations have been solved numerically. On the basis of the results, it can be found that the water circulation includes two circulation cells located at each sides of the constructed freeway, which is responsible for the transportation of a higher volume of sediments. In comparison with the constant water depth at the lake, flow potential functions and velocities due to the dominant winds stress, has been found to have some similar patterns, except in their magnitude, quantity and direction.
