Detection of chlorophyll-a in urban water body by remote sensing

Water quality monitoring is one of important method for solving water pollution problem. Chlorophyll-a concentration is one of the indicator which can describe eutrophication of water bodies. In this paper, water samples and their hyper spectral reflectance data were collected simultaneously, and then analyzed in laboratory. Results show that water bodies in Shijiazhuang city, north part of China, has low level chlorophyll-a concentration, and chlorophyll-a concentration can be detected by hyper spectral reflectance data indirectly, which by using difference of reflectance in 749nm and 703nm, especially in northpart of China.
