simulation of thermal stratification and dissolved oxygen concentrations using ce-qual-w2 model (case study: shahid rajaee dam)
introductiondue to shortage of fresh water resources, the quality of impounded water behind the dams becomemore important than how it was previously as a source of fresh water resource. thermal regime anddissolved oxygen concentration are factors that affect the quality of water reservoirs.many lakes show vertical stratification of their water masses, at least for some extended timeperiods. the...
متن کاملtotal dissolved solid modeling; karkheh reservoir case example
the karkheh dam reservoir with a capacity of more than 5 billion cubic meter is the largest dam in iran with both agricultural and drinking usages. its hydrodynamics and water quality were modeled and simulated to analyze the total maximum daily load (tmdl) of total dissolved solids (tds). the simulation was supported with measurements of temperature and tds measurements during two years. a lat...
متن کاملImproved Thermal Predictions in CE-QUAL-W2
Recent modifications to the transport scheme within the two-dimensional hydrodynamic and water quality model CEQUAL-W2 have resulted in a significant improvement in the prediction of temperature distributions by reducing numerical diffusion. These changes allow for a more accurate description of wind effects in the model. This paper briefly describes the modifications to CE-QUAL-W2 and presents...
متن کاملAssessment of Ilam Reservoir Eutrophication Response in Controlling Water Inflow
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...
متن کاملprediction of thermal stratification in proposed bakhtyari reservoir with ce-qual-w2
construction and operation of dams have two main effects on streams. at first it increases detention time and then leads to thermal stratification. changing of water quality is the result of these effects and the outflow has different physical, chemical and biological characteristics from inflow.in this study thermal regime in proposed bakhtyari reservoir was simulated with ce-qual-w2 model. th...
