Problems solved by technology
At present, the main methods and means to study the sediment resuspension process are laboratory tank tests, on-site tank observations and on-site time-series observations of suspended sediment concentration. Due to the complexity of ocean dynamics and sedimentation processes, on-site tank observations are limited by their own working principles , the test results sometimes have large errors, and the results of the indoor tank test are difficult to apply to the field environment
Using the time series observation data of suspended sediment concentration to study resuspension requires separating the suspended sediment concentration produced by advection and dif

Embodiment Construction
[0017] Such as figure 1 , a method for separating suspended sediment concentration in seabed sediment resuspension process, is characterized in that, comprises the steps:
[0018] a. Use the seabed base to invert the suspended sediment concentration through optical instruments (such as OBS) or acoustic instruments (such as ADV), and collect time series observation data of suspended sediment concentration;
[0019] b. Perform quality inspection on the collected suspended sediment concentration time series observation data, eliminate noise and abnormal values, and use interpolation to fill in the gaps;
[0020] c. Determine the input matrix of the observation signal according to the suspended sediment concentration time series observation data after the quality inspection; perform centralization and whitening preprocessing on the input matrix: centralization is to convert the original time series data into a time series with a mean value of 0, and whitening is Carry out a l...

The invention provides a method for separating suspended sediment concentration in a process of resuspension of submarine sediment. The method comprises the following steps of collecting one or a group of suspended sediment concentration time sequence observation data by utilizing a seabed base, carrying out pretreatment on the obtained mixed suspended sediment concentration observation data, separating mixed suspended sediment concentration by utilizing a blind source separation method, and carrying out character matching and identification on a suspended sediment concentration separation result to obtain the resuspension suspended sediment concentration of the submarine sediment. According to the method for separating the suspended sediment concentration in the process of the resuspension of the submarine sediment, which is disclosed by the invention, the suspended sediment concentration generated by advection and diffusion functions in suspended sediment concentration observation data can be separated, the resuspension suspended sediment concentration data is more accurate, the error of the observation result of the sediment resuspension process is reduced, a new manner is provided for the research on the sediment resuspension, and a new way is also provided for the source apportionment of multiple-source suspended sediment concentration.
Description
technical field [0001] The invention belongs to the technical field of marine monitoring, and relates to a method for separating the concentration of suspended sediment, in particular to a method for separating the concentration of suspended sediment in the resuspension process of seabed sediment. Background technique [0002] Sediment resuspension is a common phenomenon in marine processes and an important source of suspended sediment in muddy nearshore seas. Under the action of ocean dynamics, sediment is often in the continuous cycle dynamic process of starting, transporting, settling, resuspension, and retransportation. When resuspension occurs, part of the sediment enters the water body, which will inevitably lead to changes in the concentration of suspended sediment. Accurately obtain resuspension The change of suspended sediment concentration during the suspension process is the key to the study of sediment resuspension. At present, the main methods and means to stud...
