The pyRIVE model aims at representing the biogeochemical functioning of aquatic system, by simulating concentrations of oxygen and nutrients dissolved (NH4+, NO2-, NO3-, PO43-, SiO2) and particulate (PIP, BSi), suspended matter, dissolved and particulate organic carbon (3 classes of biodegradability), dissolved gases (CO2, N2O et CH4). Biological compartments are represented by 3 taxonomic classes of phytoplankton (diatoms, chlorophyceae, and cyanobacteria), 2 types of zooplankton (rotifers with short generation t…
