Using versions to evaluate water caliber is changing into more and more vital around the world. to be able to be ready to increase a great version, it will be significant to have an outstanding quantitative and ecological description of actual, chemical and organic procedures in ecosystems. Such descriptions should be known as ``submodels''.

Example text

Most organic compounds and micro­ organisms and some inorganic compounds are degraded by natural processes of self-purification, so that their concentrations decrease with time. This type of pollutant is termed nonconservative, and the actual rate of decay is a function of many factors, including the particular pollutant, the quality of the receiving water, temperature and other environmental factors. 2) where c, = pollutant concentration at time t C() = pollutant concentration just below discharge at r = Ü Κ = decay constant for that particular pollutant and temperature Many inorganic substances are unaffected by self-purification reactions, so that the concentration of pollutant below the discharge point does not change with time unless further dilu­ tion water is added in the form of tributary flows with a lower concentration of the pollutant.

7) where and are D O deficit and ulfimate B O D respectively just below the point of mixing. lk\\ - D,ik. 10) = critical deficit at time r,.. To use the above model, known as the Streeter Phelps equa­ tion, it is necessary to know the B O D rate constant and the reaeration constant for the particular stretch of the river under consideration. If the B O D and D O levels upstream of the discharge are known together with the equivalent values for the discharge, mass balances give the B O D and D O immediately downstream of the discharge point.
