The European Water Framework Directive (WFD) requires the definition of reference conditions, i.e. pristine conditions, for all surface waters. As the present state of Danish coastal waters cannot be referred to as pristine, reference conditions have to be assessed by analysis of historical data or by the use of models. Using Randers Fjord as an example,(More)
Nutrient retention was studied in the Danish estuary Randers Fjord, using 2 independent methods: (1) measurement of denitrification and nutrient flux rates across the sediment-water interface, and (2) estimations of mass balance established on the basis of hydrodynamic modelling (MIKE 12). Annual N retention estimated by hydrodynamic modelling was 460 t N(More)
