Geotechmarket – A successful funding measure of the BMBF

For the first time, special funds have been made available by the BMBF for adjusting outstanding monitoring and early warning systems to the requirements and demands of the end user and for product presentations at specialized trade fairs. In the course of the three-year funding period in the key research area »Early warning systems against natural hazards“, several projects designed promising technologies and received additional funds from the BMBF in order to be able to develop marketable prototypes together with industry partners. Good results and fieldwork with the different technologies on the Philippines, in Istanbul and in the Alps demonstrate the efficiency and integration capacity of these systems in practice. SLEWS, a sensor system for landslides of the Technical University of Aachen, has improved energy supply to the sensor nodes against external physical influences (temperature, moisture). The aim was to provide an inexpensive, certified, wireless sensor system, which can be quickly and easily installed, for monitoring slope movements and rockfalls with a simple data output. An easyto-use system is now available, and was presented to interested companies, environmental agencies and associations for the first time at the terratec 01/2001 environmental fair.

The SOSEWIN system (GFZ, HU Berlin), has aimed at the development of cheaper, more efficient and more intelligent sensor nodes (more compact design, special architecture) with a new industry partner (DResearch, Berlin) in order to improve the measurement of seismic activities and seismic early warning. A prototype sensor network with more than 40 sensor nodes will soon be available; a smaller network has already been successfully tested in Istanbul. The system will mainly be used to monitor critical infrastructures such as bridges and high-rise buildings so as to warn the population at an early stage with real-time capable data transmission and alarms. The alpEWAS system (Technical University of Munich) has together with new partners from the environmental sector (Hess & Partner, Dr. Plinninger Geotechnik) implemented the joint technology development in the form of a marketable measuring system for continuous 3D monitoring of unstable slopes using the Time Domain Reflectrometry (TDR) system, Global Navigation Satellite System (GNSS) and geotechnical standard sensors. With the aid of the funding, resistance to environmental impacts under extreme weather conditions (snowfall, driving rain) has been considerably improved. ¢
