Although traditional computationmethod can be simplified by converting spacial effect to plane problem, it is quite hard to reflect the whole and local effect by importing too much hypotheses.
This method is a simplified model for water quality prediction with simply computation and rapid speed, so it is an effective complement to the complex numerical simulation.
