Abstract Mathematical models predicting nitrogen and phosphorus concentrations in surface waters can be useful tools to evaluate measures combating eutrophication. NUSWALITE is a water quality model to predict the nutrient concentrations in high spatial and temporal detail for catchments and ‘polder areas’. The NUSWALITE model comprises the description of five main processes: i) uptake and release of nutrients by biomass, ii) mineralization of organic phosphorus and nitrogen to their mineral fractions, iii) adsorption and desorption of phosphorus and nitrogen, iv) loss of nitrogen by denitrification, sedimentation and biomass removal, and loss of phosphorus by sedimentation and biomass removal. This report includes the description of the process formulations, solution scheme, parameterization, and calculation of nutrient retention.
