The problems
On the research on bay’s self-purificability , it is difficult only to use a simple water-quality model to express self-purified course in whole bay because there are large changes in space and time for involved factors. The main element to influence bay’s self-purificability is tide, it moves in periodicity and make pollutant diluted, diffused, deposited and transported, and also influence the bay’s bio-chemical environment . In the principle, a simplied one-dimensional water-quality transpiration model is also available, it is as follows:
In real application, formula 1 can be simplied and solved by differential difference equation, the parameters Dx and Sx can be expressed by following experienced formula.
