Numerical modeling of nutrient transport to assess the agricultural impact on the trophic state of reservoirs

open access: yesInternational Soil and Water Conservation Research, 2023
A trophic state increase relates to surface water bodies nutrient enrichment, due to the chemical products used such as fertilizers in agriculture and residues from cattle raising activities.

Assessing trophic status of Suoi Hai Reservoir using Carlson’s Trophic State Index

open access: yesVietnam Journal of Earth Sciences, 2021
The water quality of Suoi Hai reservoir, the largest reservoir in Hanoi city, is being threatened by human activities of the surrounding area, as reported by the press. The trophic status of the reservoir is the result of both natural eutrophication and nutrient inputs from anthropogenic sources, particularly the leachate from a lakeside waste ...

A Machine Learning Approach for Estimating the Trophic State of Urban Waters Based on Remote Sensing and Environmental Factors

open access: yesRemote Sensing, 2021
To improve the accuracy of remotely sensed estimates of the trophic state index (TSI) of inland urban water bodies, key environmental factors (water temperature and wind field) were considered during the modelling process. Such environmental factors can

Algae and Cyanobacteria Diversity and Bioindication of Long-Term Changes in the Hula Nature Reserve, Israel

open access: yesDiversity, 2021
Lake Hula, the core of one of the most extensive wetland complexes in the Eastern Mediterranean, was drained in 1951–1958. However, about 350 hectares of papyrus marshes were allocated in the southwestern part of the previous lake and became the Hula ...

Benthic trophic interactions in an Antarctic shallow water ecosystem affected by recent glacier retreat [PDF]

open access: yes, 2015
The western Antarctic Peninsula is experiencing strong environmental changes as a consequence of ongoing regional warming. Glaciers in the area are retreating rapidly and increased sediment-laden meltwater runoff threatens the benthic biodiversity at ...

In-situ anatomical and elemental response of aquatic macrophytes against nutrient enrichment in freshwater tropical lakes

open access: yesApplied Water Science, 2022
Nutrient enrichment in lakes due to municipal wastewater discharge and agricultural run-off leads to excessive growth of algae and aquatic macrophytes leading to their altered trophic states.

Trophic State of Cibanten Watershed

open access: yesJurnal Perikanan dan Kelautan, 2018
Cibanten watershed upstream is from Karang Mount (one of that is shallow lake  Cibanten water springs), flow in Serang City and the downstream at Banten Bay. From upstream until downstream, Cibanten watershed used by various anthropogenic activities where potentially to increasing trophic state of the waters.
