1 INTRODUCTION Fluctuations in large amplitude waves (ie, large-amplitude waves) outside the tidal cycle have occurred in Tiger Beach and Oman. Tiger Beach is located on the side of the Gulf of Dalian, is half closed shallow depth of the triangular cove (Figure 1). Tide gauge station is located in the left bank of the bay, about 1km from the top of the bay, the water depth of 2.8 m. According to statistics, a total of 61 counterfeit tides of wave height greater than 20 cm occurred between 1980 and 1994 in 15 years
