Application of QUAL2Kw for water quality modeling and dissolved oxygen control in the river Bagmati

Environmental Monitoring and Assessment, 2006
A 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

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

Application of automated QUAL2Kw for water quality modeling and management in the Bagmati River, Nepal

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.

Application of QUAL2kw and Forecasting models for assessment of pollutants in upper Athi River catchment in Kenya

African Journal of Pure and Applied Sciences, 2022
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 ...
