 For the purposes of the [[:wiki:alpes|AlpES Project]], this ecosystem service is defined as "Filtration of Surface Water by Ecosystem Types". Within AlpES the outcomes of the InVEST NDR model (Nutrient Delivery Ratio) have been used to assess the nitrogen loads and the filtration capacities by different ecosystems. This model follows a mass balance approach, describing the movement of the mass of nutrient through space. Unlike more sophisticated nutrient models, NDR does not represent the details of the nutrient cycle but rather represents the long-term, steady-state flow of nutrients through empirical relationships.
+The provision dynamics of the ES [[:wiki:filtration_of_surface_water_by_ecosystem_types|filtration of surface water by ecosystem types in the Alps ]]were assessed by means of the following supply, demand and flow indicators:
+  * Supply: [[:wiki:nitrogen_removals|Potential nitrogen removals]] (kg ha<sup>-1 </sup>   y<sup>-1</sup>   )
+  * Flow: [[:wiki:nitrogen_removal_2|Nitrogen removals]] (kg ha<sup>-1 </sup>   y<sup>-1</sup>   )
+  * Demand: [[:wiki:nitrogen_loads|Nitrogen loads]] (kg ha<sup>-1</sup>   y<sup>-1</sup>   )
