      abstract     = {Deficit analysis—which principally deals with the
                      question “how big are the gaps between current water
                      status and good ecological status?”—has become an
                      essential element of the river basin management plans
                      prescribed by the European Water Framework Directive (WFD).
                      In a research project on behalf of the Ministry of Energy,
                      Agriculture, the Environment, Nature and Digitalization
                      Schleswig-Holstein (MELUND), a deficit analysis based on
                      distributed results from the water balance and phosphorus
                      emission model system GROWA-MEPhos at high spatial
                      resolution was performed. The aim was, inter alia, to
                      identify absolute and relative required reduction in total
                      phosphorus at any river segment or lake within the state
                      territory as well as to highlight significant emission
                      sources. The results of the deficit analysis were
                      successfully validated and show an exceedance of the
                      phosphorus target concentrations in $60\%$ of the analyzed
                      subcatchments. Statewide, 269 tons of phosphorus needs to be
                      reduced yearly, which corresponds to approximately $31\%$ of
                      the total emission. Detailed data as well as maps generated
                      by the deficit analysis benefit the planning and
                      implementation of regionally efficient measures, which are
                      indispensable with regard to meeting the environmental
                      quality objectives set by the WFD.},
