Abstract:With the increase of the construction of the artificial sandy beach above the tidal flats,the research of artificial beach profile’s transverse sediment transport has a very important and practical significance.It is complicated to build artificial beach on the original beach that is adapted to the coastal dynamic.The artificial beach in practical project is affected by engineering measure,so the profile form is more difficult to predict.Based on the method of physical model test,the form changes of the artificial beach profile restricted by the debris barrier and the protection of bank are studied in different water level and wave conditions.At the same time,the equilibrium profile model is used to calculate the relative stable profile,and the conditions needed to form a stable profile are obtained.The results of the experiment verify the applicability of 1:15 of the initial bank slope,and conclude that when the structure has few influence on wave,a balanced beach profile could be formed.
