Study area

  
 

Fig. 3. Nidda catchment (red: location of Rockenberg subcatchment).

  • Nidda catchment, 1942 sqkm, SW Germany
  • river Nidda: a tributary to the river Main
  • drains the >Wetterau basin, a Neogene basin framed by the Taunus uplands in the W and the Vogelsberg upland in the E;
  • basinal area characetrized by Late Pleistocene loess cover from which Luvisols developed
  • arable cultivation since the Early Neoltihic (7,500 years, incl. sparse upland settlements)

 
     
 

Approach

  
 

 

  • datamodeling of available digital soil survey data
  • database and GIS application

 

 

 

Fig. 4. Soil survay data is provided as db tables that are linked to each other by one-to-many relationships.
