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 ...

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

2020
Water 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.

RIVER WATER QUALITY MODELING BASED ON DO AND BOD PARAMATERS USING QUAL2KW SOFTWARE (CASE STUDY : WINONGO RIVER, SPECIAL REGION OF YOGYAKARTA)

Proceedings of the 7th International Conference in Sustainable Built Environment, 2023
The location of the study was on the 46.93 km Winongo River which passes through the Sleman Regency, Yogyakarta City, and ends in Bantul Regency. The Winongo River receives sources of pollutants such as domestic waste, agricultural waste, and fishery waste so river pollution occurs.
