Abstract: The present disclosure discloses a method for measuring a mudflat elevation based on remotely sensed water content, comprising steps of: measuring a spectral value of a soil surface in a mudflat area using a full-band spectrometer, analyzing a relationship between the spectral value and a soil water content of the mudflat area; building a remotely sensed water content retrieval model using a statistical correlation method; selecting a water sensitive waveband in the remote sensing data, and retrieving the soil water content of the mudflat area; analyzing a relationship between the soil water content and the mudflat likewise using the statistical correlation method; building a relational model between the mudflat water content and an elevation, and applying the model to a satellite image to obtain the mudflat elevation.
