- | The Water Filtration Supply indicator represents the amount of nitrogen that is potentially filtered by ecosystems in a given municipality. This ecosystem service is calculated using the InVEST “Nutrient Delivery Ratio (NDR)” model, specifically focusing on nitrogen. A fixed value of nitrogen input is applied to all LULC classes in order to calculate the potential filtration capability as a percentage on the total input. The model uses a mass balance approach, which describes the movement of a mass of nutrients through space. Unlike more sophisticated nutrient models, the present approach does not represent the details of the nutrient cycle but rather represents the long-term, steady-state flow of nutrients through empirical relationships. A detailed description of the model can be found at: [[http:// | + | The Water Filtration Supply indicator represents the amount of nitrogen that is potentially filtered by ecosystems in a given municipality.
