Development of a Minimalistic Data Collection Strategy for QUAL2Kw
Journal of Water Resources Planning and Management, 2015AbstractIn-stream water-quality models provide guidance in watershed management decisions by linking pollutant loads to changes in water quality. These models are particularly useful for determining wasteload allocations, developing numeric nutrient criteria, and aiding in total maximum daily load (TMDL) analyses.

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 ...

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.

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.
