Application of remote sensing techniques for water quality monitoring

A detailed study and experimental work performed to establish the properties of multispectral remote sensing techniques as applied to the monitoring of water quality, is hihhly desirable since direct synoptic field measurements concerning the quantity and type of pollutants in water is not possible at present.The multispectral characteristics of the signal received from water are a function of hydrological, biological and chemical characteristics of water, and the physical properties of the remote sensor related environment. Spectral data encompassing of the spectral region 0.36 m and 2.36 m showed that the detectibility of water pollutants, using spectral signatures in the 0.4 to 0.9 m range, is promising and feasible.
