    Geomonitoring at the Three Gorges Reservoir

    DMT participating in Yangtze research project

    Working in China through to the year 2015, the independent engineering and consulting company DMT GmbH & Co. KG will be cooperating with research teams from the German universities at Erlangen-Nürnberg, Trier, Kiel and Tübingen (which is handling coordination of the scientific efforts). The objective of the project is to examine the causes behind environmental risks associated with the Three Gorges Reservoir. The effort was initiated by the Jülich Research Centre and is being supported by Germany’s Federal Ministry of Education and Research. To be investigated here are the effects of land use changes, erosion, substances infiltrating the water, and movements of geological masses – all with an eye toward sustainable utilisation of the Three Gorges Reservoir, which confines the waters of the Yangtze River.

    The construction of the Three Gorges Dam and the world’s largest hydroelectric power plant, which has been in operation since 2009, triggered considerable resettlements of the population and changes in land use and cultivation. The resultant environmental, socio-economic and geotechnical risks are the subject of Sino-German research work.

    The primary assignment for DMT is to monitor the potential hazards in the affected area and resulting from the seasonal fluctuations in the fill level, which may exceed 30 meters. Also to be studied are interactions with the various factors behind the forces involved. Two products developed by DMT are employed in early detection and monitoring of geological risks. These are the cutting-edge “Summit M Vipa” seismograph and the “DMT Safeguard” software package.

    Over and above this, radar interferometric measurements of the earth’s surface, in the mm and cm ranges, are carried out at landslides. DMT and the Chinese partners are to lay the scientific and technical foundations for a concept governing monitoring and hazard forecasting. The project managers from DMT are Dr. Karsten Zimmermann and Dr. Paul Althaus, both employed in the Exploration & Geosurvey Division.
