“…Many investigators have addressed the issue of estimating suspended sediments with remote sensing (Alfoldi and Munday, 1978;Amos and Alfoldi, 1979;Amos and Toplis, 1985;Curran et al, 1987;Curran and Novo, 1988;Aranuvachapun and Walling, 1988;Lyon et al, 1988;Doerffer et al, 1989;Ritchie et al, 1990;Schiebe et al, 1992;Goodin et al, 1993;Mayo et al, 1993;Han and Rundquist, 1994 suspended sediment concentration in surface waters. However, few addressed the issue of reflectivity differences in between different types of soil materials.…”
