Sedimentation rates of tripton in Jurumirim Reservoir (São Paulo, Brazil)
(1996-01-01)
Sedimentation rates of particulate material and some physicochemical parameters of water were determined in October, January, April and July 1990-91 at seven stations in the Jurumirim Reservoir (São Paulo, Brazil), three ...
Heat budgets, thermal structure and dissolved oxygen in Brazilian reservoirs
(International Institute Ecology, 1999-01-01)
A comparison of the thermal regime and oxygen distribution patterns of some Brazilian reservoirs was made. A strong latitudinal dependence of surface temperature, annual mean and annual range was found. Except for Tucurui ...
Assessment of the efficiency of a trophic state index in determining the water quality of public water supply reservoirs
(Assoc Brasileira Engenharia Sanitaria Ambiental, 2018-07-01)
The aim of this study consists in the evaluation of the trophic state index (IET) efficacy as a tool in the water quality analysis of three reservoirs. The IET was calculated based on water transparency in the reservoir ...
Spatial and temporal quality of water in the Itupararanga Reservoir, Alto Sorocaba basin (SP), Brazil
(2013)
Considering the great importance of the Itupararanga Reservoir, Upper Alto Sorocaba basin/SP, this study aimed to report the variations of some parameters of water quality in the spatial and temporal gradients in this ...
Cyclopoid copepods as bioindicators of eutrophication in reservoirs: Do patterns hold for large spatial extents?
(2016-11-01)
Some species of copepods are sensitive to water quality oscillations from natural or anthropogenic causes. Information on basic ecological attributes such as abundance can be helpful in the context of hydric resources ...
From Linear Programming Model to Mixed Integer Linear Programming Model for the Simultaneous Optimisation of Water Allocation and Reservoir Location in River Systems
(MDPI, 2018)
The allocation of water flowing through a river-with-reservoirs system to optimally meet spatially distributed and temporally variable demands can be conceived as a Network Flow Optimisation (NFO) problem and addressed by ...
Water works"Maraval"
(2011-03-10)
In the foreground of the postcard, a wooden bridge and gazebo on the same compound as the Maraval Reservoir can be seen. The Maraval reservoir was built in the 1850s to supply pipe bourne water to residents in Port of Spain.
