Abstract The study explores the factors affecting sedimentation trends in surrounding catchment area of Tarbela Dam for period 1980–2017, specifically rain and temperature. Furthermore, this also investigates seasonal effects sediment loads coming into reservoir from 2007 to 2012. statistical techniques were applied estimation climate (rainfall temperature) on inflow its area. results revealed ...

After construction of a dam across a river, sediments settle behind the dam. It is important for dam designers to estimate the rate and distribution of sediments in the reservoir. In this study, the accuracy of area-increment and area-reduction empirical methods to predict the sediment distribution of Dez, Dorudzan and Shahid Abbaspour reservoirs is evaluated. The last measurement of sediment i...

This study aimed to reconstruct the sedimentation rates over time and identify changing sources of sediment in a major hydropower reservoir Tanzania, Nyumba ya Mungu (NYM). Fallout 210Pb measurements were used estimate age deposits broad changes reconstructed. Sedimentation peaks cross referenced geochemical profiles allogenic autogenic elemental constituents column confirm causal link. Finally...

Environmental Changes in a round of reservoir have dramatic influences on the sedimentation and deterioration water quality. A significant land-use change Cibalagung sub-watershed has impact quality Cirata reservoir. In this study, we used remote sensing GIS to investigate influence changes sub-watershed, 2004–2014. The total suspended solids (TSS), as main parameter quality, was determined by ...
