Abstract:
Modeling of water quality in shallow lake is the goal of this roject.Matters cycling in environment will be explained. The dissolved Oxygen will be assigned the most important factor in water quality. The phytoplankton Growth rate and fatality rate will be modeled By LOTKAVOLTERRA equations. The nitrification by nitrifying bacteria and Michael Menton equations will be explained. Modeling will be executed By System Dynamic which feedbacks are the most com ponents of it.The model will be built with equations and coefficients in literatures and this model run by VENSIM®software. We will assure by some extreme condition tests about the structure of the model and finally we will make a sensitivity analysis for three parameters of the model
