WFS Soil water conditions BB (WFS-BOWASSVERH)

The Download Service (WFS) soil water conditions of Brandenburg provides data on the characteristic values of water movement, characteristic values of water retention, wetting conditions in the soil and retention areas in the event of floods. The content was designed for scale 1: 300,000 and are for representations in scales greater than 1: 100,000 is unsuitable. Water movement and water retention: The service is based on the legend units of the soil overview map with corresponding assignment of parameterized surface soil shapes. These represent a soil-forming society per unit of legend. The individual (surface) soil forms were subjected to parameters determined by field and laboratory tests. For this purpose, the corresponding parameters were statistically derived for the same horizon-substrate combinations (usually the median value). In the case of insufficient data, due to the better consistency of the derived values with measured data from the characteristic value tables of the Soil Science Mapping Guide, 3rd edition, Hanover 1982 (Soil Science Working Group), Table 43 was used for water binding using linking rule 1.11 (methodological documentation soil science, Hennings et al 2000) and Table 49 was used for water movement using linking rule 1.12 (dito). Wetness ratios: The service is based on the Legend Units of the Ground Map. These are soil-forming societies. The enumerated (area) soil forms were evaluated according to their statement on soil water conditions. This was done primarily on the basis of the soil systematic units involved. These units provided the information on the degree of wetting and the area proportions for distribution. In the case of groundwater soils, the degree of wetting depends on the depth of the groundwater level in the soil area up to a maximum of 2 m below the corridor and in the case of backwater soils on the intensity or duration of the leachate present in the soil after precipitation and prevented from seepage.
