Inspire View Service: Soil/leakage rate and nitrate discharge hazard in Brandenburg (WMS-SO-SWRPNAG)

The interoperable INSPIRE representation service (WMS) Soil (leach water rate and nitrate discharge hazard in Brandenburg) represents the leachate rate and the potential nitrate discharge hazard in the state of Brandenburg. The annual leachate rate describes the mean amount of leachate estimated by the TUB-BGR method in mm/a, which leaves the soil downwards taking into account the capillary ascent. The potential risk of nitrate discharge is assessed by leaching nitrate from the root space of the vegetation by leaching soil water. The place of assessment is the lower limit of the rooted soil layer. The quotient of leachate rate and usable field capacity in the effective root space (nFCs) initially provides the exchange frequency of the plant-available soil water. This is classified in 5 levels (very low (1), low (2), medium (3), high (4), very high (5)) and results in the potential nitrate discharge risk. The landing method for the calculation of the potential nitrate discharge hazard represents a modification of the bundle method in which the particular hazard to groundwater sites and bog sites is taken into account. Further information can be found here: https://geo.brandenburg.de/karten/htdocs/21042020_Sickerwasserrate.pdf According to the INSPIRE data specification Soil (D2.8.III.3_v3.0), the contents of the floor map are INSPIRE-compliant. The WCS includes the following layers: SO.minimumSeepageWaterRate, SO.medianSeepageWaterRate, SO.maximumSeepageWaterRate, SO.minimumRiskOfNitrateLeachingStateMethod, SO.medianRiskOfNitrateLeachingStateMethod, SO.maximumRiskRiskOfNitrateLeachingStateMethod, SO.minimumRiskOfNitrateLeachingFederalMethod, SO.medianRiskOfNitrateLeachingFederalMethod and SO.maximumRiskOfNitrateLeachingFederalMethod. — The compliant INSPIRE view service (WMS) Soil provides information on the seepage water rate and the risk of potential nitrate leaching in the state of Brandenburg. The annual seepage water rate is the mean amount of seepage water (mm/a) that leaves the soil downwards, calculated with the TUB-BGR method. The potential risk of nitrate leaching describes the risk of nitrate leaching from the root zone of the vegetation through seeping soil water. The place of assessment is the lower limit of the rooted soil layer. The ratio of seepage water rate and available water capacity of the root zone (nFKWe) provides the exchange frequency of the soil water available to plants. This ratio is converted to a categorical variable of five levels (very low (1), low (2), medium (3), high (4), very high (5)), which is a qualitative measure of the potential risk of nitrate leaching. The state method for calculating the potential risk of nitrate leaching represents a modification of the federal method, in which the particular vulnerability of sites influenced by groundwater and peatland sites is taken into account.
