in this research, a 2d laterally averaged model of hydrodynamics and water quality, ce-qual-w2, was applied to simulate water quality parameters in the ilam reservoir. the water quality of ilam reservoir was obtained between mesotrophic and eutrophic based on the measured data including chlorophyll a, total phosphorus and subsurface oxygen saturation. the ce-qual-w2 model was calibrated and ver...

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...

This study assesses spatial and temporal variation in environmental variables in relation to phytoplankton community size and composition in a typically eutrophic river reservoir (Hai River, northern China). The aim is to identify environmental parameters governing spatial and temporal differences in phytoplankton density and composition. Physicochemical parameters, including nutrient concentra...

Management decisions related with water quality in lakes and reservoirs require a combined land-water processes study approach. This study reports on an integrated watershed-reservoir modeling methodology: the Soil and Water Assessment Tool (SWAT) model to estimate the nutrient input loads from the watershed, used afterwards as boundary conditions to the reservoir model, CE-QUAL-W2. The integra...

We briefly report here the occurrence of toxic blooms in the eutrophic reservoir Billings, São Paulo city, Brazil. Water samples were collected in May 2004, during a cyanobacterial bloom. The presence of toxic species was confirmed by using PCR amplifications of a fragment region of genes encoding microcystin synthetase-mcyB. The determination of toxins was performed by liquid chromatography co...

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...
