QUAL2Kw is a framework for the simulation of water quality in streams and rivers. Dynamic diel heat budget and water quality kinetics are calculated for one-dimensional steady-flow systems. The framework includes a genetic algorithm to facilitate the calibration of the model in application to particular waterbodies. The genetic algorithm is used to find the combination of kinetic rate parameter...

Abstract The rivers rejuvenate themselves by traveling over a distance, thereby they assimilate the pollution load and cause their own self-cleansing, also termed ‘Self-purification capacity’. To ascertain such assimilative capacity of river system, various water quality models (WQMs) were studied. Out numerous WQMs, six including QUAL2Kw, WASP, SWAT, SIMCAT, MIKE-11, CE-QUAL-W2 selected studie...

Usually, the main source of water is a river, which makes it essential to ensure that from not polluted and in accordance with quality standards. Water can deteriorate as result domestic industrial waste. This measured based on several parameters, such concentration pH, nitrate, phosphate, fecal coliform water. QUAL2KW be used analyze river order solve quality-related problems. The Semarang Reg...

human activities in the fields of agriculture, municipal and industry introduce significant amounts of nutrients and organic materials into the rivers and streams resulting in their contamination. computer models such as qual2kw are used extensively for water quality management of rivers and streams. the qual2kw model is a one dimensional, non-uniform, steady water quality model, which has been...
