Abstract

In this study a numerical model was developed to determine the tidal regime and its power in any location of the seas and the oceans. The methodology employed is firstly to use the measured water level data for a limited period and then to use the least square method and low pass FIR filter with a suitable cut frequency, to calculate components and phases of tides. Next by using the calculated amplitudes of tidal components the tide form number of the study area is calculated. In this way the type of tide of the area and its efficient component and astronomical period is determined. Finally using these information as well as gravity acceleration and water density the tidal power is estimated. In a case study the change of water level was measured in Bandar Abbas Coast of Persian Gulf for 29 days. Then using the developed model the tidal power in the study area was estimated. Considering this power it can be decided if devices for absorbing tidal energy can be economical to install in this area
