A model of three species of phytoplankton (diatom, green and blue green algae) coupled with macrophyte and sedimentary model has been developed for shallow lake. Phosphorus and nitrogen return fluxes from the bottom sedimento overlying water are simulated by model for the sediment -water exchange of nutriets. hedevelopent of otamogen pectinatus L. is simulated by macrophyte model. The verification of the model for phytoplnkton, phosporus, amonium nitrate return fluxes was conducted using observed data in Lake Veluwe in 1986. The fitness beteen obseved nd is computed values suggest that the model is capable of reproducing the real picture of phytoplankton and Potamogeton P.L. development in Lake Veluwe for short and long term time period. One of the rationale conclusion from the model for Lake Veluwe is that the declining of phytoplankton concentration followed the water quality is improved, as consequences light can be penetrated into deeper water column and macrophyte can be grown. All model equations and the application of the model as tool for analyzing and describing interactions between the biological processes, utrients reycling, macroyte developing in Lake Veluwe is subject of this study.
