description The invention relates to a remote sensing monitoring method for the silt scouring and silting amount of an ultrahigh turbid river, which comprises the following steps: taking the water body reflectivity of a near infrared band as a characteristic wave band for reflecting the suspended sediment concentration of an ultrahigh turbid water body, and dividing the characteristic wave band by the sum of the water body reflectivity of green light, red light and short wave infrared bands to obtain a sensitive index Index of the suspended sediment concentration of the ultrahigh turbid water body; constructing a surface suspended sediment concentration remote sensing model based on Index data; the method comprises the following steps: respectively constructing a water column suspended sediment concentration profile distribution function and a water column flow velocity profile distribution function through function fitting by utilizing water column suspended sediment concentration and flow velocity data monitored by a h
