乌苏里江水深遥感反演

Abstract

Based on analyses of theoretical models of the fathoming method by using satellite remote sensing, we determined the most suitable spectral band for water depth retrieval using the SVC HR-1024 spectroradiometer. A water depth remote sensing model for the Wusuli River was established and its accuracy improved by analyzing the sensitivity to water of di?erent bands of the HJ-1a CCD camera output. Our results show that the acquisition of water depth from remote sensing could supply a new and more rapid way for obtaining the talweg, river terrain information and information on river pattern change for the Wusuli River.
