Water balance and climate change

  • To quantify water balance components in high spatial and temporal resolution
  • To assess total runoff and groundwater recharge for regional water resources management
  • To predict the impact of climate change on sustainably manageable groundwater recharge, soil water balance and irrigation demands
  • Models: GROWA, mGROWA


  • To identify input pathways and to analyze the actual N and P pollution of groundwater, surface waters and coastal areas
  • To locate “hot spot areas” and to determine the nutrient reduction required to reach environmental quality targets
  • To predict the impact of management adaptations
  • Models: DENUZ-WEKU-MEPhos
