The results of a case study on sand bypassing in a logistic fishing port at Kelarabad City at Caspian Sea described and discussed in this paper. The project location (51.2541E, 36.7025N) shown in Figure 1. The present study benefited from 31 years (from 1983 to 2012) wave data from Monitoring & Modeling Studies of Iranian Coasts project 1 (Fig. 2). Offshore wavestransmitted to nearshore area at a depth of 5 meters in front of the Port. The approved layout for the Port shown in Figure 2. It estimated that a distance of about 2.5 km at theeast side of the breakwater would eroded as result of Port construction. Sand bypassing proposed as a measure to alleviate this problem.
