Lake Biogeochemical Food Web Model

Ryan Roper -

This is a nutrients, phytoplankton and zooplankton model with dissolved oxygen dynamics for a vertically stratified lake system with river inputs. The major processes simulated are the uptake of dissolved inorganic N by algae, consumption of algae by herbivorous zooplankton, consumption of herbivorous zooplankton by carnivorous zooplankton, and death and respiration of algae and zooplankton. The dissolved oxygen fluxes associated with reaeration, photosynthesis and decomposition are also simulated.
