Assessment of Trophic Status for Nansi Lake Using Trophic State Index and Phytoplankton Community
2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010The present study was to investigate the trophic state of Nansi Lake, a shallow lake employed in the South-to-North Water Diversion Project in China. Based on water transparency, total phosphorus (TP) and chlorophyll a (chl a) concentration, the modified method of Carlson's trophic state index (TSIM) was applied to assess the lake's trophic status.

AbstractIn running waters, apart from structural degradation, nutrient input becomes increasingly important. To investigate the indicator values of as many species of submerged macrophytes as possible numerous samples of the sediment within macrophyte stands and the overlying water were taken in running waters throughout Bavaria, Germany.

Environmental Monitoring and Assessment, 2020
The relationships between nutrients and the trophic state of Borçka dam reservoir in the Çoruh River Basin, which is located in the Eastern Black Sea region of Turkey, were evaluated using the trophic state index (TSI), trophic level index (TLI), and statistical analysis.

Trophic state of the northern Adriatic
2013The annual mean trophic index and efficiency coefficient were used to address the trophic state of the northern Adriatic in the last forty years. Differences in the efficiency of nutrients use between the western (more eutrophied) and eastern (more oligotrophic) part were identified at the beginning of the investigated period.

Trophic states and nutrient storage of reservoirs in Chongqing
Chinese Journal of Geochemistry, 2008The trophic states of 35 reservoirs were investigated in the region of Chongqing, Southwest China. The results showed that the concentrations of nutrients and chlorophyll a were high and organic pollution and transparence (SD) were low in the water body.

A dynamic lake model for trophic state prediction
Ecological Modelling, 1978Primary production per unit lake area, ΣP, is selected as a measure of the trophic state of a lake. The relationship between phosphorus loading and ΣP is simulated by means of a dynamic, one-dimensional vertical diffusion model for phosphate [OP] and particulate phosphorus [PP]. ΣP is described by a non-linear function of [OP] and [PP] which takes into

TROPHIC STATE INDICES: RATIONALE FOR MULTIVARIATE APPROACHES
Lake and Reservoir Management, 1984ABSTRACT Trophic state indices (TSIs) have been widely used to rank and classify lakes. Applications and limitations of TSIs are discussed, and types of TSIs developed previously are reviewed. An index is a summary statistic, and most trophic indices have been multivariate metrics, reflecting the complexity of the concept of trophic state.
