Analyzing the Effect of Temperature on DO and BOD of the Tapi River using QUAL2Kw Model
International Journal of Innovative Technology and Exploring Engineering, 2023 Environmental pollution and climate change is the ultimate result of rapid urbanization. The change in environmental conditions due to undesirable human activities increases local ambient temperature hence it is leading to a rise in the river water temperature. Tapi river is the main source of drinking water for Surat city, Gujarat, India. A stretch of

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.
