Trophic state assessment of global inland waters using a MODIS-derived Forel-Ule index [PDF]
Remote Sensing of Environment, 2018 Eutrophication of inland waters is considered a serious global environmental problem. Satellite remote sensing (RS) has been established as an important source of information to determine the trophic state of inland waters through the retrieval of ...

The trophic state of shallow lakes in The Netherlands
Netherlands Journal of Aquatic Ecology, 1996A study has been carried out on the development of an ecological assessment method for shallow lakes in The Netherlands. Analyses of eutrophication characteristics of 93 lakes with, in total, 127 sampling localities gave insight into some of the steering variables, such as total-P, total-N, chlorophyll-a and transparency.

Addressing the trophic status in urban ponds: An evaluation of current trophic state indexes
Austral Ecology, 2023AbstractPonds are generally understudied. Quality problems in urban freshwaters can arise from eutrophication, and trophic status classification gives information related to their ecological situation. Ponds may strongly differ from larger lakes for which most current trophic status classification methods have been developed.

Journal of Environment Sciences, 2022
Eutrophication of wetlands has been considered as a global level environmental problem due to wide range of environmental impacts caused by it. All the lake bodies are subjected to natural eutrophication process but anthropogenic activities like excessive utilization of inorganic fertilizers containing phosphorus and nitrogen in the farmlands which ...

A trophic state index for lakes1
Limnology and Oceanography, 1977A numerical trophic state index for lakes has been developed that incorporates most lakes in a scale of 0 to 100. Each major division (10, 20, 30, etc.) represents a doubling in algal biomass. The index number can be calculated from any of several parameters, including Secchi disk transparency, chlorophyll, and total phosphorus.

TROPHIC STATE INDICES IN RESERVOIRS
Lake and Reservoir Management, 1984ABSTRACT Trophic state index systems provide a framework for data summary, interpretation, and communication. Carlson's indices can be viewed as reexpressions of bivariate regression analyses derived from phosphorus-limited, northern, natural lakes. Several studies have shown that lakes or reservoirs which are nitrogen limited and/or have relatively ...

Trophic State of LaFarge Reservoir
Journal of the Environmental Engineering Division, 1979A review is presented of three different methods used in analyzing the eutrophication potential of the Lake LaFarge Reservoir in Wisconsin. The trophic models examined include two computer models and one empirical model. The assumptions used in each model are described and the results of each modeling effort presented.

Trophic state analysis of inland lakes
Remote Sensing of Environment, 1976Abstract The formulation of a trophic state index using remote sensing data is discussed. A multivariate analysis technique is applied to the data to formulate a trophic state index which combines selected indicators of eutrophication into a single numerical expression. Results are presented for a group of inland lakes in Southern Michigan.

Trophic state, eutrophication and nutrient criteria in streams
Trends in Ecology & Evolution, 2007Trophic state is the property of energy availability to the food web and defines the foundation of community integrity and ecosystem function. Describing trophic state in streams requires a stoichiometric (nutrient ratio) approach because carbon input rates are linked to nitrogen and phosphorus supply rates. Light determines the source of carbon. Cross

Fuzzy estimation of trophic state using satellite data
2008 IEEE International Conference on Fuzzy Systems (IEEE World Congress on Computational Intelligence), 2008Eutrophication is one of the major water quality problems in developing and developed countries. Generally, trophic state of water sources is under a strict watch and is determined by in situ water sampling for some important water resources. However, a limited number of water samples provide insufficient statistical confidence with an overall ...
