Abstract

in this paper , the modeling of tidal currents at the confluence of Karoon and Arvand rivers has been modeled using mike 21 model . the numerical model is developed based on the eulerian method and is used to determine the flow pattern of water flow from continuity and momentum equations ( navier - stokes equations in depth ) . triangular unstructured mesh is used for mesh scheme . the mesh of the study area is in a way that in the range of confluence , finer grained is performed . in addition , the number of nodes and elements used in this study are 9832 and 18553. in the following , three open boundary (Karoon river, Arvand river and sea ) are considered for the model . time series of level changes have been applied to the sea border. on the boundary of rivers, the flather condition is used .at this points, the velocity and level of water and discharge are defined. the level of water level has exerted influence on the model . after calibration , the comparison of the results of the model with the observational measurements shows that the root mean square error for the water surface level is 0.14 m and for the water velocity is 1 m / s
