SALMO (Simulation by an Analytical Lake Model, Benndorf 1979) is a dynamic ecological model that simulates the most important pelagic food-web compartments of lakes and reservoirs. Its state variables are soluble reactive phosphorus, anorganic nitrogen, two or more functional phytoplankton groups, zooplankton, oxygen and detritus. Recent versions have additional state variables for suspended particles and humic substances. Important other mechanisms (e.g. predation by fish or sediment-water interactions) are also included by rate equations. With the exception of three lake specific parameters, all other parameters are considered general constants, which are widely applicable to lakes and reservoirs of different trophic state. The two-box-version SALMO-2 is a spatially aggregated model with two horizontal layers (epilimnion and hypolimnion) and a variable mixing depth. If horizontal exchange rates are available (e.g. from a 3D hydrodynamic model) multiple horizontal compartments can be combined. The model can be used within scenario analysis applications for decision making and as a research tool. SALMO-1D and SALMO-HR are vertically resolved 1D versions. The ecological part is called SALMO-1D and the hydrodynamic-ecological coupled model is called SALMO-HR. |
