The invention provides a device for monitoring seabed shallow sediment erosion resuspension in an internal wave environment. The device comprises a snorkeling system, an observation platform and a supporting system, the snorkeling system comprises a glass floating ball combination, a mooring rope, a subsurface buoy, a Kelvar cable and a limiting cylinder. The observation platform comprises a middle supporting rod, a stabilizing circular ring, a supporting rod, an acoustic Doppler current profiler, a sediment capturer, a circular ring with a hole, an optical backscattering turbidity meter, a battery bin, a conductivity-temperature-depth meter, a supporting plate and an acoustic Doppler velocimetry. The supporting system comprises a buffering device, a vertical supporting rod and a gravity anchor. According to the technical scheme of the invention; the device aims to directly reach the seabed to collect and obtain accurate suspended sediment concentration information on the basis of notdestroying the seabed environment. The influence of the seabed on the internal solitary wave suspended sediments is discussed; and the device is good for evaluating the suspension quantity caused by internal solitary waves and the influence on the seabed deposition process, is good for further predicting the seabed evolution, is good for accurately describing the sediment movement and improving the sediment resuspension quantity prediction level in application, and also provides a new technology and means for sediment resuspension research.
