Fisheries in large tropical reservoirs in South America
The present status of large reservoir fisheries and their management in large reservoirs in South America are reviewed. There is a brief discussion about reservoir typology, and how most of it is inappropriate to fish. ...
Reservoir design and operation: Effects on aquatic biota-a case study of planktonic copepods
Copepod assemblages from two cascade reservoirs were analyzed during two consecutive years. The upstream reservoir (Chavantes) is a storage system with a high water retention time (WRT of 400 days), and the downstream one ...
Performance of the Equivalent Reservoir Modelling Technique for Multi-Reservoir Hydropower Systems
This paper investigates the validity of a simplified equivalent reservoir representation of a multi-reservoir hydroelectric system for modelling its optimal operation for power maximization. This simplification, proposed ...
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 ...
Development Of Complex Layered And Fractured Reservoir Models For Reservoir Simulation
(Springer HeidelbergHeidelberg, 2017)
Sedimentation rates of tripton in Jurumirim Reservoir (São Paulo, Brazil)
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 ...
Phytoplankton structure in two contrasting cascade reservoirs (Paranapanema River, Southeast Brazil)
A series of eleven reservoirs was constructed in the Paranapanema River, southeast Brazil, for hydropower production. The phytoplankton structure and its relations with the environmental variables were studied in two of ...
