Table 2: TSI and corresponding values of Chl-a, NO2-N, and SDD computed using Model A. It is noticeable that this model gives negative numbers (shown as “—” dash), which implies the nonapplicability of this model for Chl-a concentrations less than 0.04 mg m−3 and NO2-N concentrations less than 0.71  g  .
