 Information on rural household diffuse source (private sewers) is located in the file GeoData.txt. The source has a flow and concentrations of total nitrogen and phosphorus and fraction of IN and SP. The diffuse source is divided into two parts, where the distribution is determined by a general parameter (//​locsoil//​). One part is added directly to the local river. The other part is added to soil water in the bottom soil layers in the catchment area of all land classes with a distribution proportional to the classes’ area. Information on rural household diffuse source (private sewers) is located in the file GeoData.txt.

-The potential uptake is used to calculate the absorption of IN and SP from the soil water (see section Vegetation nutrient uptake). The actual uptake will be limited by the nutrients available.
