Abstarct: Sea waves usually pass large amount of water toward the beach. This amount of water must come back toward the sea again, And for this purpose, In some areas of the beach, unpredictably, Sea water make waterways to the sea Where water flows With great speed against the waves (ie, from the beach to the sea). this flows are completely different from the sea waves this kind of waves call coastal currents, rip currents or deadly currents which is caused by different reasons but the same property in all cases is wave breaking and moving it toward the sea from the point where the water level is higher to the point where a lower height until reach to balanced level. In this study effecting factors of rip current and power has been investigated in order to slow down the rip current. Rip current is dependent of wind characteristics, wave bed and tidal energy. Mike 21 software modules Spectral Waves Fm (SW) and Flow Model Fm (FM) was used to investigate the factors listed in Anzali coast and it was found that the rip current velocity is directly related with wave height, wave period, wind speed, the number of sediment bar and length rip channel and has reverse relation with width rip channel and water depth. To ensure that the results of the software are correct the results have been compared with the results of the air cushion in the depth of 10.5 m Bandar Anzali And it have been proved that the results were correct.
