AB: The earthquake and the tsunami-event on December 26th, 2004, caused the loss of life of more than 120,000 people, the missing and injuring of more than 110,000 people and the destruction of about 80% of all private houses, basic infrastructure and public facilities in the coastal region in the Province of Nanggroe Aceh Darussalam. The tsunami waves caused large scale coastal salt water intrusions and destroyed thousands of shallow drinking water wells. This presentation documents a project between the Indonesian and German governments that is dedicated to re-install the public life and to secure the future health and wealth of the people that suffered from the consequences of the catastrophe. The focal point is the water assessement in coastal areas of Aceh about six months after the tsunami. The aim of the project of the Federal Institute for Geosciences and Natural Resources (BGR) is to assist the Directorate General for Geology and Mineral Resources (DGGMR), the National De-velopment Planning Agency (BAPPENAS) and the Executive Agency for the Rehabilitation and Reconstruction in Aceh and Nias (BRR) in their efforts to plan and realize a sustainable reconstruction of community infrastructure (like freshwater supply) by providing geophysical, hydrogeological, geological and topographic data that will serve as a base for spatial planning. The main activities comprise an airborne geophysical survey and a hydrogeological reconnaissance survey. The target areas are: Banda Aceh (Aceh Besar), Calang (Aceh Raya), and Meulaboh (Aceh Barat). The helicopter-borne survey was conducted by the airborne group of the German Federal Institute for Geosciences and Natural Resources (BGR) from August to November 2005. The BGR helicopter-borne geophysical system includes five-frequency electromagnetics (HEM), magnetics (MAG) and gamma-ray spectrometry (SCI). The electromagnetic system provides information about the distribution of electrical conductivity in the earth down to a maximum depth of 150 m. The presentation will give first results and interpretations of the airborne and surface water assessments.
