Increasing accuracy of TPXO global tidal model using TELEMA numerical model in Bushehr Bay
Abstract:   (5286 Views)
Abstract
Several methods have been developed such as experimental methods, numerical and computational models for studying the prediction of water level. The purpose of this research is to evaluate and verification Telemac's numerical tidal model in Bushehr Bay waters using measured data. In this regard, the Telemac 2D module has been used to simulate the tide in a A course, 15 days from 01/08/2011 in Bushehr Bay Area. After the preparation of hydrographic data, the creation of irregular triangular mesh, the application of tidal data as astronomical force on the border, water level and tidal current velocity was modeled. In order to verify the water level, tidal range, flow rate and friction coefficients of the model, the data from water level measurement and tidal current velocity recorded by the port authorities were used. In the next step, the water level, the tidal current velocity were extracted by the global TPXO model using Matlab software. The tidal analysis results from the global ocean drag model were compared with the results of modeling. The results of the research indicate that the RMSE error rate decreased from 14% to 7% for the water level and from 20% to 5% for the tidal current velocity after modeling on the TPXO data. The shape factor value was 1/1 that showed tide in Bushehr Bay mixed, often half a day.
Keywords: TELEMAC Model, Water Level, Bushehr Bay, TPXO, Tide.
