Abstract Details

2009, MA, University of Cincinnati, Arts and Sciences : Geography.
The aim of this research was to study the seasonal and annual changes in the water quality based on the landsat measures of turbidity and chlorophyll-a. The indices were applied to a 95 km segment of the Ohio River where the USEPA had collected actual turbidity and chlorophyll-a samples the same day as the Landsat-7 overpass. Pearson correlation coefficient was calculated for the chlorophyll-a and turbidity indices, which was -0.938. A regression model was also developed to quantify chlorophyll-a (dependent variable) from turbidity (independent variable). The regression model had R2 value of 0.879, indicating a good fit. For the annual analysis of water quality, only the turbidity index was taken into consideration. The turbidity level is constant in the years 2000 and 2001. There has been a significant decrease in the concentration of turbidity from the year 2002 indicating improvement in the water quality. Efforts taken by the government and other agencies to improve the water quality could be the reason for constant turbidity index.
