Koto Panjang Reservoir is one of the hydroelectric power plants in Indonesia, located Kampar Regency, Riau Province. This paper aims to determine water quality and tropic status Reservoir. The research was carried out along Reservoir, covering floating net cages area, inlet, outlet, center reservoir. Water samples were collected twice a year, February September 2017. results showed that reservo...

The Çaygören Reservoir was sampled monthly from February 2007 to January 2009 at three stations to determine the relationships between the chlorophyll-a (Chl-a) dynamics and soluble reactive phosphorus (SRP), nitrate-nitrogen (NO3-N), ammonium-nitrogen (NH4-N), water discharge, water transparency, water temperature (T), specific conductance (SC) and pH. Thermal stratification occurred in the re...

Eutrophication is considered as a serious problem in water reservoirs. Awareness about the eutrophic status of each reservoir could help in providing a better understanding of the problem in a global scale. The present study was conducted to assess temporal and spatial eutrophication index in a water reservoir (Sahand dam) in the northwest of Iran. Physico-chemical parametres that are effective...

Yanghe Reservoir is an important source of drinking water for Qinhuangdao City, North China; however, in recent decades this water source has been eutrophic with recurrent summer cyanobacterial blooms. The trophic grade of the system in summer was mesotrophic-eutrophic in 1990 and became hypertrophic in 2011. The nutrient availability is extremely high during the entire year, and the water temp...

Abstract Eutrophication is a common problem for the dams situated within an urban or agricultural catchment with high source of untreated plant nutrients. This can negatively affect hydro ecosystem, recreational and other uses water. On hand, such eutrophic could also be rich nutrients use. Thinking irrigation as alternative means reservoir water management, suitability was investigated Roodepl...

In this paper we describe a record of planktonic foraminiferal relative abundance changes in Core T89-40 retrieved from the Walvis Ridge, SE Atlantic. The planktonic foraminiferal relative abundance changes reflect past (sub)surface water hydrography during the Mid-Pleistocene Transition. Statistical analysis shows that most variability in the planktonic foraminiferal relative abundance record ...
