Demands for professional knowledge Walter Brüsch (geologist – groundwater, drinking water, organic micro pollutants)
Geological Survey of Denmark and Greenland
Melting ice on Greenland

The thermohaline circulation in the northern part of the Atlantic ocean
Groundwater level rise in sandy areas but drop in clay areas=>dry summers, wet stormy winters

Professional knowledge
Consequences of Sea Level Rise :
Nature in coastal areasInvasive species, sea or land migrationDykes and low land areas near the coastNumber of storms and increasing intensity – 1/100 years storm each year?Salt water intrusion in coastal groundwater reservoirsTemperature PrecipitationDrought or too much water
Threads to be met now:
Flooding of cities, houses, vulnerable nature etc in lowlandsRoads and transport, sewer and drainsTourist industry Water level in rivers and estuaries Invasive insectsNew pesticidesDrinking water resourcesEtcEtcEtc
Expert/ professional knowledge
Local authoritiesCoastal experts, engineers (harbour, waste water, floods etc)Biologist, e.g. marine and zoologist, ecology, etc Climate – modelers, meteorology, etcGeology – drinking water, etc
