摘要

Daily water quality data from six U.S. Geological Survey (USGS) monitoring stations along the Great Miami River and digital land use/land cover and elevation data for the same watershed were Analyzed. The validity of using electrolytic conductivity as a water quality indicator was examined By correlating conductivity with 199 other water quality variables, 60 of which were significantly Correlated with conductivity. Positive correlations existed between conductivity and dissolved Materials. Negative correlations existed between conductivity and insoluble or suspended materials.
