Impoundment of rivers by dams is widespread and one of the most devastating anthropogenic impacts to freshwater environments. Linking theoretical and applied research on river impoundment requires an improved capacity for predicting how varying degrees of impoundment affects a range of species. Here, growth of 14 North American sunfish species resilient to river impoundment was compared in rive...

Index words: Reservoir sedimentation Pb-210 dating Sediment retention Cs-137 dating The singlemost important factor affecting the longevity of US dams is sedimentation, reducing and perhaps eliminating the reservoir capacity for future sediment storage and floodwave attenuation. A better understanding of the sedimentation rates and sediment dynamics is required for a better management of these ...

The benthos of Lake Creek, Lincoln County, Montana were sampled in 1984-85 to determine the effects of a 2.5 years old tailings impoundment located adjacent to the stream. Sampling results were compared spatially in the 1984-85 data set, and temporally with a baseline data set collected three years prior to installation of the impoundment. Lack of replication in the baseline sampling design pre...

Inland fisheries contribute towards food security for rural communities living close to large aquatic systems. However, sustainable inland rely on accurate biological information the target species at proposed fishery location. In this study, Labeo rosae Steindachner, 1894 and Oreochromis mossambicus (Peters, 1852) were determined Flag Boshielo Dam, Olifants River system, Limpopo province, as p...

Hydrological alternation can dramatically influence riparian environments and shape riparian vegetation zonation. However, it was difficult to predict the status in the drawdown area of the Three Gorges Reservoir (TGR), because the hydrological regime created by the dam involves both short periods of summer flooding and long-term winter impoundment for half a year. In order to examine the effec...

This paper aims to introduce a numerical technique for forecasting the hazard caused by disaster chain of landslide blocking river-dam breach floods through an integration distinct element method (DEM) and well-balanced finite volume type shallow water model (SFLOW). A toppling slope in reservoir area, southeastern Tibetan Plateau, was chosen study. Creep has been observed potential instability...

The global increase in energy demand has triggered a boom the construction of hydropower dams worldwide affecting biological communities. Our objective is to study zooplankton (Rotifera, Cladocera and Copepoda) community structure during after impoundment newly constructed reservoir, provide valuable knowledge on species diversity, dynamics be considered future management plans. period was char...
