Water Quality Modeling For Pollutant Carrying Capacity Assessment Using Qual2Kw In Bedog River [PDF]
Indonesian Journal of Geography, 2018 Considering the abundance of potential pollutant sources along Bedog River, i.e. highly dense residential areas, agricultural lands, and industrial areas, this study aimed to quantitatively assess the Pollutant Load (PL) and Pollutant Carrying Capacity (PCC) of the river based on Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD)parameters.

Numerical Modelling of Heavy Metal Dynamics in a River‐Lagoon System
Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019 This paper describes the development of a two‐dimensional water quality model that solves hydrodynamic equations tied to transport equations with reactions mechanisms inherent in the processes. This enables us to perform an accurate assessment of the pollution in a coastal ecosystem.
