Water quality modeling for urban reach of Yamuna river, India (1999–2009), using QUAL2Kw [PDF]
Applied Water Science, 2015 The study was to characterize and understand the water quality of the river Yamuna in Delhi (India) prior to an efficient restoration plan. A combination of collection of monitored data, mathematical modeling, sensitivity, and uncertainty analysis has been done using the QUAL2Kw, a river quality model.

Ecological Modelling, 2007
Abstract The Bagmati River in Kathmandu Valley (Nepal) receives seven major polluted tributaries. Discharges of wastewaters containing degradable organics and nutrients have resulted in decrease in DO concentrations along its course. A one-dimensional stream water quality model QUAL2Kw was calibrated and confirmed using the data in 2000.

Numerical Simulation of Water Quality and Self-Purification in a Mountainous River Using QUAL2KW
Journal of Environmental Informatics, 2020Understanding the water quality in mountainous rivers is critical for sustainable water resources management. By using the rivers’ self-purification to improve water quality is also the most economical and sustainable way to clean water. In the present study, the QUAL2KW model is applied to investigate the water quality and self -purification ...

Monte Carlo Simulation and Fuzzy Modelling of River Water Quality for Multiple Reaches Using QUAL2kw
Water Science and Technology Library, 2020Water quality of the river is associated with various processes, defining its complexity in nature. Monitoring of surface water can produce uncertain results due to spatial and temporal variations, fluxes in river cross section, and depth of flow.

MODELING OF WATER QUALITY IN THE PAMPANG RIVER, MAKASSAR CITY, USING THE QUAL2KW APPLICATION
JEBE: Journal of Environment Behavior and EngineeringThe Pampang River is a tributary of the Tallo River that plays an important role as a source of clean water, irrigation, and support for community activities in Makassar City and its surroundings. However, increased industrial and residential activities around the river have caused a decline in water quality.

Environmental Monitoring and Assessment
Remediation of black and odorous water in urban rivers is a key priority for urban water governance, but identifying pollution sources and optimizing strategies remain challenging. This study targeted the 3.2-km Qianjin Canal (Tianjin), integrating the QUAL2Kw model with a self-developed pollution source contribution module (two-step method) to ...
