Identifying sedimentation processes in the Coata River, Altiplano of the Puno department, Peru, by the 210Pb method
(2019-11-01)
The rivers, lakes and dam sediment analyses are able to predict the back conditions of these ecosystems and determine how the environment changed as a result of anthropogenic activities. In this way they can be used as ...
Factors that control the spatial and temporal distributions of phosphorus, nitrogen, and carbon in the sediments of a tropical reservoir
(2018-01-01)
The impacts of anthropic activities have had profound effects on the nitrogen (N) and phosphorus (P) cycles in many aquatic ecosystems. We investigated the spatial and temporal distributions of carbon (C), N, and P in the ...
Impacts of agricultural expansion on floodplain water and sediment budgets in the Mekong River
(2022-02-01)
In this paper, we address the impact of agricultural expansion on hydrological patterns of water and sediment budget in one of the largest floodplains along the Cambodian Mekong since the 1980s, using field (water level, ...
Impact of bottom trawling on deep-sea sediment properties along the flanks of a submarine canyon
(Public Library Of Science, 2014-07)
The offshore displacement of commercial bottom trawling has raised concerns about the impact of this destructive fishing practice on the deep seafloor, which is in general characterized by lower resilience than shallow ...
Background values, distribution and contamination of metals in the sediments of the Pontevedra Ria (NW Spain)
(Soil & Sediment Contamination, 2007)
Thirty-seven surface sediment samples were taken in the Pontevedra Ria (NW Iberian Peninsula), and metal concentrations (Cd, Co, Cr, Cu, Fe, Ni, Pb, and Zn) and organic/inorganic parameters were determined in order to ...
Impact of copper sulfate application at an urban Brazilian reservoir: A geostatistical and ecotoxicological approach
(2018-03-15)
A landscape ecotoxicology approach was used to assess the spatial distribution of copper in the recent bottom sediment (surficial sediment) of a Brazilian subtropical reservoir (the Guarapiranga reservoir) and its potential ...
Dredging impacts on the toxicity and development of sediment quality values in a semi-arid region (Ceará state, NE Brazil)
(2021-02-01)
Sediment dredging impacts coastal environments by promoting the resuspension of fine particles and remobilization of contaminants that may trigger toxic effects. In this study, we evaluated the sediment quality in harbor ...
Modeling the Suspended Sediment Transport in a Very Wide, Shallow, and Microtidal Estuary, the Río de la Plata, Argentina
(Blackwell Publishing, 2019-10)
The impact of the diverse processes responsible for the distribution of suspended sediments in the wide, shallow, and microtidal Río de la Plata estuary and the adjacent shelf is studied by means of a set of process-oriented ...
An environmental magnetism approach to assess impacts of land-derived sediment disturbances on coral reef ecosystems (Cartagena, Colombia)
(Pergamon-Elsevier Science Ltd, 2018-06)
We used environmental magnetism methods to study recently deposited marine sediments from the estuarine ecosystems on the Caribbean coast of Colombia. Cartagena region has undergone an increasing sediment load during the ...
