      abstract     = {With regard to the creation of river basin plans and
                      programmes of measures according to the EU Water Framework
                      Directive, the importance of model-supported analyses of
                      nutrient inputs into aquatic systems and the localization of
                      source areas is increasing. Especially in lowland regions
                      artificial drainage installations play a major role, but
                      little information exists concerning their location within
                      larger river basins. Therefore, artificially drained lands
                      were identified by interpreting aerial photographs and
                      typical site conditions of the drained plots were derived. A
                      GIS-based approach was then developed, which allows the
                      delineation of artificially drained lands by combining
                      various site conditions like soil properties and land use
                      type. After checking the validity of a derived map for the
                      River Ems basin (12 940 km(2)) With small-scale drainage
                      installation maps, the approach was applied to northwestern
                      Germany (98 000 km(2)). This was followed by a discussion of
                      results and uncertainties. Copyright (C) 2008 John Wiley
