 ==== General description ====
-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://data.naturalcapitalproject.org/nightly-build/invest-users-guide/html/ndr.html.</font|http://data.naturalcapitalproject.org/nightly-build/invest-users-guide/html/ndr.html.</font]]>

 <font 14px/inherit;;inherit;;inherit>The amount of nitrogen that is potentially filtered in a municipality can be calculated from the outputs of the Nutrient Delivery Ratio model by subtracting the nitrogen exported per municipality from the total nitrogen load in the same area. This value is then normalized on the area of the municipality in ha multiplied by 300kg in order to obtain the percentage of Nitrogen being potentially filtered per LAU2 polygon.</font>
