[0051] In this embodiment, when the sand wave simulation test system provided by the present application is used to perform a sand wave simulation test, the water in the second water tank 300 flows into the sand wave water tank 200 through the water inlet 201 of the sand wave water tank 200, and flows into the first water tank 100 from the water outlet 202 of the sand wave water tank 200.
