==== Filtration of surface water by ecosystem types - Demand ====

<font 14px/inherit;;inherit;;inherit>**General description**</font>

<font 14px/inherit;;inherit;;inherit>The Water Filtration demand indicator describes the amount of nitrogen that is introduced into the ecosystem per municipality in kg/year. This includes the nitrogen emitted in the atmosphere and then deposed in the landscape and the nitrogen from the fertilization in agriculture.</font>

==== Input Data ====

  * <font 14px/inherit;;inherit;;inherit>NOx emissions in the atmosphere.</font>Source:[[http://www.ceip.at/new_emep-grid/01_grid_data_2015| EMEP, http://www.ceip.at/new_emep-grid/01_grid_data_2015]]
  * <font 14px/inherit;;inherit;;inherit>Nitrogen loads from fertilization per different LULC</font>
==== Calculation processes ====

<font 14px/inherit;;inherit;;inherit>**(1****)****Calculate N emissions per municipality **</font>

<font 14px/inherit;;inherit;;inherit>The Emep gridded data on NOx are used to calculate the average emissions at the LAU2 level, these data are after converted in N equivalent as described in Umweltbundesamt (2017)</font>

<font 14px/inherit;;inherit;;inherit>**(2****)****Calculate N inputs based on LULC**</font>

<font 14px/inherit;;inherit;;inherit>The N loads quantities per agricultural areas are based on literature (Bundesministerium für land- und forstwirtschaft, umwelt und wasserwirtschaft, 2017), the average N input per municipality is then calculated.</font>

<font 14px/inherit;;inherit;;inherit>**(3) Calculate total N inputs**</font>

<font 14px/inherit;;inherit;;inherit>The total N inputs per municipality are therefore obtained summing up the results from point 1 and point 2.</font>
