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.

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.
