After the earthquake and the tsunami event on December 26, 2004, the Indonesian and German governments set up a project dedicated to re‐installing the public life of the people in the coastal region of Aceh Province in northern Sumatra, Indonesia. As the tsunami waves caused large‐scale coastal salt‐water intrusions and destroyed thousands of shallow drinking‐waterwells, the focal point was water assessment along the shorelines of Aceh about nine months after the tsunami. The target areas were the city of Banda Aceh and the district of Aceh Besar on the north coast and the area on the west coast between the towns of Calang (district of Aceh Jaya) and Meulaboh (district of Aceh Barat). A helicopter‐borne survey including electromagnetics (HEM), magnetics and gamma‐ray spectrometry was conducted by the airborne group of the German Federal Institute for Geosciences and Natural Resources from August to October 2005. The HEM surveys revealed shallow coastal salt‐water occurrences caused by the tsunami, deep salt‐water occurrences up to several kilometres inland, and a number of potential freshwater resources. Numerous requests for information on the geological and hydrogeological situation at sites for planned water‐wells were successfully evaluated.
