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.

WebThe trophic state index (TSI) is commonly adopted for guiding and managing the ecosystems and water quality of inland waters [ 11 ], which assumes algae biomass as the key descriptor for trophic state classification [ 12, 16 ]. In this study, TSI was calculated based on Chl a concentration and its formula see (4) [ 12 ]. (4) WebA 15-year estimated Trophic State Index (eTSI) for Michigan inland lakes is available, and it spans seven datasets, each representing 1 to 3 years of data from 1999 to 2013.

WebThe Trophic State Index (TSI), developed by R.E. Carlson, is among the most commonly used indicators of a lake’s trophic state. This index is actually composed of three … WebTrophic State Index. One way to characterize the health of lakes is by using phosphorus, chlorophyll a, and secchidepth transparency data to calculate the Trophic State Index … The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to … See more Carlson's index was proposed by Robert Carlson in his 1977 seminal paper, "A trophic state index for lakes". It is one of the more commonly used trophic indices and is the trophic index used by the United States Environmental Protection Agency See more Both natural and anthropogenic factors can influence a lake or other water body's trophic index. A water body situated in a nutrient-rich region with high net primary productivity may be naturally eutrophic. Nutrients carried into water bodies from non-point sources such … See more • Biomass (ecology) • Eutrophication • Nonpoint source pollution • Secchi disk See more A lake is usually classified as being in one of three possible classes: oligotrophic, mesotrophic or eutrophic. Lakes with extreme trophic indices may also be considered … See more Often, the desired trophic index differs between stakeholders.
