A MODEL FOR ESTIMATING SUSPENDED SOLID POLLUTANTS IN WATER USING RADIOMETRIC AND SPECTROPHOTOMETRIC DATA

Abstract

Monitoring of suspended sediments has always been of great interest to water quality managers. The advantages of remote sensing have been recognized, since it is the' only method that gives a good description over large areas. -Qualitative estimation of suspended sediment is a relatively easy tasks, since it involves several image processing procedures that can be found in most image processing packages. Quantitative estimation is a laborious and tedious work. The simplest approach to quantitative estimation involves statistical correlation with field measurementrs obtained simultaneously. In the present study the effect of sediment size, variation in viewing geometry and source illumination geometry with varying suspended sediment concentration total dissolved salinity and chlorophyll concentration on the variation of reflectance with wavelength is being studied and general models are proposed to predict suspended sediment concentration.
