The increasing impact of climate change on water resources and the environment, especially with regard to water scarcity and droughts, as well as the permanently increasing water demand of all economic sectors and the population, pose enormous and diverse challenges for water resources management in many regions of the world. In order to adapt to climate change, secure water supply and sustainable use of water resources, adequate response measures and strategies are required. In particular, the increase in extreme dry periods is leading to bottlenecks and conflicts in the use of water resources. RWC, therefore, offers consulting services and studies in the following fields:

  • Water resources inventory
  • Assessment of the water management conflict potential and bottleneck risk for agriculture, inland navigation, industry, water supply, and hydropower generation
  • Development and evaluation of water management measures and strategies
  • Studies on economic efficiency (e.g. cost effectiveness, cost-benefit analyses)
  • Environmental impact assessment of water management measures
  • Impact of climate change on water resources
  • Development of climate change adaptation measures for different uses (agriculture, inland navigation, industry, water supply, and hydropower)
  • Water management under water scarcity
  • Agricultural hydraulic engineering, irrigation agriculture and agricultural production
  • Hydro(geo)logical investigations and groundwater modeling
