A review on longshore sediment transport rate formulas in sandy coast

Accurately predicting the coastal sediment transport rate under wave action is an important scientific problem in the field of sandy coast research. According to the research progress of the longshore sediment transport rate formulas for decades, the development process of various research methods and their representative results are reviewed by classifying the results according to the research methods, taking into account the time logic. The theoretical basis, consideration factors and data sources of each achievement were discussed, and the prediction accuracy of commonly used formulas were tested by using measured data such as field prototype sand, indoor prototype sand and indoor light weight sand. The results show that the Sun Linyun formula has the best agreement with the measured data, and has obvious advanced characteristics compared to the other longshore sediment transport rate formulas. On this basis, the direction in which research can be further deepened in the future is discussed.
