Stochastic trophic level index model: A new method for evaluating eutrophication state

Journal of Environmental Management, 2021
The trophic state index (TSI) and trophic level index (TLI) are commonly used methods for evaluating the eutrophication state of lakes and reservoirs. However, they are unable to overcome uncertainties such as calculation errors and spatial heterogeneity of evaluation indicators.

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 ...

Major nutrients and chlorophyll dynamics in Korean agricultural reservoirs along with an analysis of trophic state index deviation

Journal of Asia-Pacific Biodiversity, 2017
The main objectives of this study were to determine how Asian monsoon influences nutrient regime, suspended solids, and algal chlorophyll (CHL) in 182 agricultural reservoirs, and then to develop the empirical models of nutrients-chlorophyll.

A simple oxygen index for trophic state description

Marine Pollution Bulletin, 1991
Abstract The trophic state of a coastal marine ecosystem can be easily described by a simple oxygen index: Euclidean distance between the oxygen surplus at the surface and the oxygen deficit at the bottom. Basically, the oxygen index measures the oxygen inbalance within the water column which is a consequence of the growth and decay of organic matter;

Using reservoir trophic-state indexes in optimisation modelling of water-resource systems

Environmental Modelling & Software, 2011
Water quality is an important factor to consider when attempting to reconcile mathematical optimisation modelling with the physical reality of water-resource systems. In particular, when the greater part of water resources in supply systems comes from artificial reservoirs, as in Mediterranean regions, a simplified approach based on the attribution of ...
