Application of Qual2Kw model as a tool for water quality management: Cértima River as a case study
Environmental Monitoring and Assessment, 2011 Modelling can be a useful management tool because models allow the understanding of water body response to different pollution pressure scenarios which may help on the decision-making process and in prosecuting the Water Framework Directive objectives. This study aims to evaluate the usage of simple water quality models (Qual2Kw) applied to small river

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.

Water pollution in the Athi river drainage basin, the fourth largest drainage basin in Kenya, has the potential of adversely impacting the aquatic biota and communities living downstream of the river. The upper part of the basin has experienced rapid industrialization in the recent past and there has also been increased encroachment of wetlands and ...

Application of QUAL2Kw for water quality modeling and dissolved oxygen control in the river Bagmati
Environmental Monitoring and Assessment, 2006A stream water quality model, QUAL2Kw, was calibrated and validated for the river Bagmati of Nepal. The model represented the field data quite well with some exceptions. The influences of various water quality management strategies have on DO concentrations were examined considering: (i) pollution loads modification; (ii) flow augmentation; (iii) local

Monte Carlo Simulation and Fuzzy Modelling of River Water Quality for Multiple Reaches Using QUAL2kw
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.
