      abstract     = {Particularly in lowland regions, the artificial drainage of
                      land plays an important role for runoff processes and for
                      the non-point input of nutrients and pesticides into surface
                      waters. However, spatially differentiated data are usually
                      not available so that such drainage cannot find due
                      consideration in the modelling of large river basins. For
                      this reason, a first attempt was made in some test areas to
                      identify drained areas by interpretation of aerial imagery.
                      In a next step, these data provided the basis for the
                      development of a GIS based method that allows estimating the
                      location of potentially drained areas by a combination of
                      different site factors. Having validated the derived
                      drainage maps by comparison with large-scale drainage plans
                      of the Ems river basin, the method is now being applied to a
                      98,000 km(2) region in North-western Germany.},
