Abstract
One of the main and effective components in the formation of hydrodynamic conditions and characteristics of coastal areas is tidal. In this research, the pattern of fluctuations in water level and tidal flow in Arvand River is studied. The results of these studies will be used for sedimentation, erosion and coastal morphological changes. The purpose of this study was to evaluate and validate the Arvandrood plume numerical hydrodynamic model using field measurements at tidal stations and achieving a tidal plane pattern. This numerical model has been developed based on the Eulerian method and has been used to determine the pattern of flow of water flow from continuity and displacement equations. The hydrodynamic modulus is the basic modulus of the flow model, it is necessary to explain that this simulator module solves on a network with structure and governing equations using finite difference. In this research, a 70x70 depth-of-dimensional file system was networked, two open borders (the boundary of the sea and the upper boundary of the river) were considered for the model. The downstream boundary of the time series of water level changes was applied to the upstream boundary Water level changes have been applied to boundaries as a constant number. After calibration, the comparison of the model results with field measurements shows that the mean squared error for the water level level is 238 m and for the water velocity, it is 127.0 m / s.
