A COMPREHENSIVE STUDY ON THE PERSIAN GULF HYDRODYNAMICS USING PMO DYNAMICS NUMERICAL MODEL

Tides, winds, wave radiation stresses and density and thermal gradients are the main factors that affect the circulation pattern in the Persian Gulf. In shallow waters,sharp gradients in bathymetry make the hydrodynamics more complicated. Since numerical modeling is highly dependent on the input parameters, i.e. coastline,bathymetry, and open boundaries, model calibration is also required to optimize unknown parameters i.e. bed roughness. This study utilizes an Iranian numerical model (PMODynamics) for simulation of hydrodynamics in the Persian Gulf. For the wind field the model uses the simulated results of WRF model Ghader et al. (2016), and radiationstresses are imposed from WaveWatchIII modeling results Jedari Attari et al. (2016). A new approach for bed friction calibration is also presented.
