There are few reports on the vertical distribution of water quality and its influence on underwater light field. In our study, we analyzed the vertical distribution of water quality based on the in situ data in Lake Chaohu, and studied their influence on diffuse attenuation coefficients of downwelling irradiance Kd via Hydrolight simulation. It was indicated that the suspended matter and colored dissolved organic matter (CDOM) were relatively vertical-uniform in Lake Chaohu; excluding algae scums at the surface, the vertical profiles of chlorophyll-a conformed to Gaussian distribution; the complex Kd in vertical was affected by chlorophyll-a and inorganic suspended matter. The analysis on vertical distributions of water quality and its influence on Kd could be the basis for further studying the influence of algae vertical heterogeneity on underwater light field in Case II waters. |
