Desert flood disaster monitoring method

The invention discloses a desert flood disaster monitoring method, relates to the technical field of desert flood disaster monitoring, and mainly aims to provide a high-precision and high-sensitivity method for early warning and monitoring desert flood disasters. According to the main technical scheme, the desert flood disaster monitoring method comprises the following steps that S1, a 3D-BOCT geometric model is established for sand grains with different internal structure characteristics, and a finite element method is used for calculating a flowing potential coupling coefficient (SPCC) so as to construct a flowing potential response database; s2, collecting a sand grain sample in the monitoring area, carrying out a dense sand grain column flow potential experiment, and comparing an experiment result with a database result to obtain an internal structure characteristic parameter and a xi potential of the sample; s3, on the basis of the parameters, establishing a detailed flow potential database for a specifi
