Study of Channel Rip Mobility Pattern

Rip currents are the most visible features of surf zone that extend from the shoreline to the sea and are classified based on the mechanism of the controlling forces governing the surf zone. In this research, at first a pattern is presented to show the quality of the Channel rips mobility using the Mike21/3 software. In the next step, the presented pattern is verified and confirmed using the CERC equation. The results of the model are then compared with field observations of other researchers by examining the mean rip mobility rate (V) and alongshore current velocity (vl), which shows a very good agreement. The main finding of this study indicates that the longshore mobility of Channel rips depends on the bed slope and depth of the channels. In addition, it was found that the intermediate beaches are conducive to the formation of this particular type of rip currents.
