Study on the river suspended sediment concentration of Huma abandoned gold mining areas based on remote sensing images

Based on the field data, remote sensing spectrum reflectance value of river suspended sediment in Huma abandoned gold mining areas, taking Landsat TM image as the main data, simulated and analyzed the spectral signature among 4 bands from the visible to the near-infrared of sandy water, and retrieved the suspended sediment concentration. The result indicates that the SSC has increased distinctly and part of the region has converted from low concentration to middle ones in recent ten years.
