shahrechay dam is located at 12th km of shahrechay river in urmia. this study was conducted for a year (spring to fall, 2007) to identify different species of benthic organisms in the dam. considering the relevant topographic status like the local depth and water speed, 6 sampling stations were chosen and sampling was done in shallow locations of the river by means of superficial method. in thi...

[1] Lakes impounded by moraines may be considered hazardous in glaciated areas throughout the world because dams can fail suddenly producing destructive floods with peak discharges far in excess of normal flows. Here we present a comprehensive case study in the Zurich, Switzerland, area that reveals several independent lines of evidences for the occurrence of a Late Pleistocene ( 13,760 calibra...

The paper reports on the flora along the banks of Lake Nubia and the long-term changes that have taken place since the formation of the Aswan High Dam (AHD) Lake about 40 years ago. Both aquatic and shoreline vegetation were studied in 15 transects located across the lake, from Debeira (337.5 km south of the Aswan High Dam), to the Dal Cataract (500 km south of AHD). Water temperature, pH, diss...

Diatoms samples in Zayandeh Rood Dam Lake were taken in four stations from surface, 0.5 and 3 m depths of water in three replicate by Nansen sampler. Additional samples were taken from the surface with plankton net. Diatoms samples fixed with 4% formaldehyde and were concentrated and identified using microscope at 400 x. Salinity, NO3, PO4 and SO4 were measured using standard methods (APHA). In...

This study aimed to determine the species composition of two algal associations in Karakaya Dam Lake. For this purpose, monthly variations phytoplankton and seasonally epipelic algae occurring dam lake were studied between June 2010 May 2011. Five stations selected A total 38 taxa belonging Bacillariophyta (27 taxa), Charophyta (2 Chlorophyta (3 Cyanobacteria Miozoa taxa) Ochrophyta (1 taxon) i...

Renewable energy is one of the most important factors for developed and sustainable societies. However, its utilization in electrical power grid systems can be very challenging regarding rates predictably. depends mainly on environmental conditions such as rainfall-runoff ratios temperature. Because that, expected production heavily fluctuates, which makes prediction calculation feed-in into ch...

Presenting water quality data for stakeholder meetings is often challenging. Section 603 of the Energy Act requires dam owners to hold stakeholder meetings on lake water quality issues during the FERC re-licensing process. Traditionally, maps, tables, and graphs have been distributed at stakeholder meetings to present water quality data, which is often perceived as misleading and confusing. Thi...

The Three Gorges Dam, located in the largest endemic area of schistosomiasis in China, is one of the world's largest hydroelectric projects to date. Some large-scale hydro projects have resulted in schistosomiasis emergence or re-emergence. Therefore, the dam's potential impact on the transmission of Schistosoma japonicum has raised concerns from medical researchers worldwide. A systematic lite...
