Thesis (M.S.)--Michigan State University, 1997.

Due to the rapid, economic growth of Taiwan and the lack of effective wastewater treatment, Taiwan rivers, such as the Chilung River, have become polluted with increases in suspended sediments and biological oxygen demand, and decreases in dissolved oxygen. The Taiwan EPA field teams collected suspended sediments concentration (SSC) water quality samples. Remotely sensed image reflectance values have been correlated with SSC.

520 $a Due to the rapid, economic growth of Taiwan and the lack of effective wastewater treatment, Taiwan rivers, such as the Chilung River, have become polluted with increases in suspended sediments and biological oxygen demand, and decreases in dissolved oxygen. The Taiwan EPA field teams collected suspended sediments concentration (SSC) water quality samples. Remotely sensed image reflectance values have been correlated with SSC.
520 $a Three multi-temporal Landsat TM images from 1993 to 1995 and an April 1996 Airborne MSS image of the Chilung River were obtained. Landsat TM image reflectance values were normalized, transformed into radiance values, and regressed against monthly SSC data. The Airborne MSS image was geometrically resampled using ground control points and reflectance values were regressed against SSC: and turbidity values.
520 $a Regression analyses yielded significant correlations between SSC and Landsat TM Band 4, R$\sp2$ = 0.44, p = 0.009. Natural log(SSC) and TM Band 4 correlation was more significant, R$\sp2$ = 0.57, p = 0.002. Band ratios generated significant correlations between ln(SSC) and the (Band 4/Band 2) ratio, R$\sp2$ = 0.66, p $<$ 0.001.
520 $a Regression results between Airborne MSS Bands 8 and 9, and SSC levels yielded R$\sp2$ of 0.38 and 0.37, both p = 0.001. The turbidity and ln(turbidity) regressions against Airborne MSS Band 8 yielded similar results, R$\sp2$ = 0.38, p = 0.001.
