Water quality modelling
From Wikipedia, the free encyclopedia
Water quality modelling involves the prediction of water pollution using mathematical simulation techniques. A typical water quality model consists of a collection of formulations representing physical machanisms that determine fate and transport of pollutants in a water body. Models are available for individual components of the hydrological system such as surface runoff; there also exist basinwide models addressing hydrologic transport and for ocean and estuarine applications.
[edit] Formulations and associated Constants
Water quality is modelled by one or more of the following formulations:
- Advective Transport formulation
- Dispersive Transport formulation
- Surface Heat Budget formulation
- Dissolved Oxygen Saturation formulation
- Reaeration formulation
- Carbonaceous Deoxygenation formulation
- Nitrogenous Biochemical Oxygen Demand formulation
- Sediment oxygen demand formulation (SOD)
- Photosynthesis and Respiration formulation
- pH and Alkalinity formulation
- Nutrients formulation (fertilizers)
- Algae formulation
- Zooplankton formulation
- Coliform bacteria formulation (e.g. Escherichia coli)
