The aim of the European Water Framework Directive is the achievement of a good ecological or rather ecological potential and chemical status for surface waters, as well as a good chemical and quantitative status for groundwater until 2015. For the river basin Weser the target concentrations will not be achieved by 2015. For exemptions extended deadlines until 2021 and 2027 are possible. Hence the aim of the AGRUM+ project is to analyze nutrient inputs and nutrient concentrations until 2021 and to conduct scientific analysis for the design of measure plans and their implementation. For this the AGRUM Weser model network consisting of the models RAUMIS, GROWA, DENUZ/WEKU, MEPhos and MONERIS is further developed and adapted. Results show that the past trend of decline of nutrient surpluses will be further continued until 2021 which also leads to a reduction of nutrient inputs into ground and surface waters. Nevertheless, in the baseline 2021 the target concentrations for the nutrients nitrate and phosphorous for ground- and surface water will not be achieved even considering an impact delay. The amount of necessary measures and the regional hot-spots of measures show that an increase in agri-environmental measures as well as a moderate intensification of the manure regulation will not be sufficient to achieve the water protection targets.
