In October 2014, the Minister of Environment announced that Denmark got its 1st generation River Basin Management Plans (RBMP) related to the Water Framework Directive (WFD). The plans were heavily delayed and the scientific rationale behind the plans have been subject to extensive criticism, why improvements were called for, for the 2nd generation of RBMPs. Primo 2013 the work to improve and develop the tools for 2nd generation was initiated and on 22. of December, the new RBMPs were made public, the result of an interesting and professionally challenging project. As part of the 2nd generation of RBMPs were the development of a marine modeling tool based on mechanistic models. These mechanistic models describe the causal link between the physical parameters (wind, currents, mixing etc.), and the chemical and biological parameters (nutrients, primary production, organic matter mm.), which are important for ecosystem functioning. Important inputs to the models are therefore both meteorological data and information on nutrient input from Denmark, as well as from our neighbors around the Baltic Sea. Following the model build the results were used to develop relationships between nutrient loadings from Denmark and environmental status, and hence, providing the water authorities with an improved tool for setting differentiated actions and estimate nitrogen targit loads within each specific water body.
