Ground map of Lower Saxony 1 : 50 000 - leachate rate (1991-2020)
Description
The map shows the average annual leachate rate for the 30-year period 1991-2020.
The rate of leachate (mm/year) from the soil is the essential quantity for the recharge of groundwater and the transfer of substances from the soil into the groundwater. It depends on the use (arable land, grassland or forest), the climate and the soil characteristics. It describes the amount of water that seeps from the soil body into the deeper subsoil. Methodologically, the size is derived according to the TUB-BGR method (DWA, 2016). The main soil characteristic for the leachate rate is the amount of soil water available to plants (Wpfl), important climate parameters are precipitation and potential evaporation according to FAO. The degree of sealing of the soils is not taken into account in the evaluation on a medium scale. The method is only applicable for arable land with a slope of < 3.5% and grassland and forest land with a slope of < 18%, as the parameter surface runoff is not included in the calculation.
