Discharge pulses of hydroelectric dams and their effects in the downstream limnological conditions: A case study in a large tropical river (SE Brazil)
(2009-12-01)
To address daily fluctuations in electricity demands, the quantities of water passing through the turbines of hydropower plants can vary significantly (up to fourfold) during a 24-h cycle. This study evaluates the effects ...

The variability of particle backscattering coefficient in an oligo-to-hypertrophic cascading reservoir system: implications to TSM bio-optical model development
(Springer, 2016-06-01)
The particle backscattering coefficient (b(bp)) has been obtained either by equipment or semi-analytically based on relations between b(bp) and the remote sensing reflectance (R-rs). Correlation between b(bp) and R-rs can ...
Retrieving Total Suspended Matter in Tropical Reservoirs Within a Cascade System with Widely Differing Optical Properties
(2017-12-01)
Total suspended matter (TSM) is an important indicator of water quality and has an adverse effect on light propagation in the water affecting the primary production. Moderate resolution imaging spectroradiometer (MODIS) ...
Single tuned algorithm to estimate the SPM concentration in a cascade reservoir system using OLI/L8 images
(2020-12-01)
Suspended particulate matter (SPM) affecting light propagation in the water column, which, in turn, affects primary production, is considered an important water quality indicator. Monitoring SPM in cascading reservoir ...
Phytoplankton assemblages in a reservoir cascade of a large tropical - subtropical river (SE, Brazil)
(Instituto Internacional de Ecologia, 2010-10-01)
As assembleias fitoplanctônicas de oito reservatórios do rio Paranapanema foram estudadas durante dois anos consecutivos. Chlorophyceae e Bacillaryophyceae foram os grupos dominantes em riqueza. O elevado número de táxons ...

The α and β diversities in the fish assemblages of the promiss̃ao reservoir (SP-Brazil): Scales, complexities and ecotone heterogeneity
(2001-01-01)
This paper characterizes the fish assemblage and its interaction with different ecotones within the reservoir. The transformation of a river basin into a cascade of reservoirs produces new ecotones which interact differentially ...
