Trophic state index

WebCTSI consists of the concentration of three items of water quality parameters: Transparency (SD), Chlorophyll-a (Chl-a), Total Phosphate (TP), which are calculated to form an index value, and determine the eutrophication level of reservoir water quality. SDTransparence;Chl-a:Chlorophyll-a;TP:Total Phosphate;TSI Exponent … WebThe trophic state index is calculated using a simple linear regression with Secchi disk depth (SDD), elevation, nitrogen, and phosphorus as its predictors. Associated with each predictor is a coefficient α. Figure 2 depicts all the elements of the POLR model.
