Determination of Trophic Status and Floating Net Cages Carrying Capacity in Jatigede Reservoir

Determination of the Relationship Between Biodiversity and Trophic Status of Wahiawa Reservoir

investigation on the trophic status of ekbatan reservoir: a drinking water supply reservoir in iran

background: eutrophication is one of the detrimental environmental problems in water reservoirs dye to the irregular introducing nutrients (phosphorus and nitrogen). this study aimed to explore the eutrophication state of ekbatan reservoir, hamadan, western iran. methods: monthly sampling was conducted during april 2010 to march 2011. seven sampling stations were selected in the various locatio...

Enhanced load-carrying capacity of hairy surfaces floating on water.

Water repellency of hairy surfaces depends on the geometric arrangement of these hairs and enables different applications in both nature and engineering. We investigate the mechanism and optimization of a hairy surface floating on water to obtain its maximum load-carrying capacity by the free energy and force analyses. It is demonstrated that there is an optimum cylinder spacing, as a result of...

planktonic Frequency and Biodiversity survey of Shadegan wetland and determination of its trophic status

In this study frequency and composition of plankton in Shadegan wetland was carried out in 5 stations during 2007-2008. Genus qualitative identification and their composition and quantitative frequency aspect were studied (for phytoplankton chlorophyll a). Frequency of total 42 genus phytoplankton in 4 classes Bacilariophyceae (Diatom), Cyanophyceae, Chlorophyceae and Dinophyceae are 69.4, 22.2...

The influence of fish culture in floating net cages on microbial indicators of water quality.

This work was carried out to analyse the microbiological parameters of the water quality of a reservoir used for the irrigation and culture of tilapia (Oreochromis niloticus) in floating net cages. The physico-chemical parameters, counts of mesophilic total aerobic bacteria, total and thermotolerant coliforms and fecal streptococci, and the presence of Escherichia coli in samples of water colle...
