The Aggenalm slide - a tesng site for an integrave 3D early warning system - alpEWAS status report - John Singer*, Peter Wasmeier**, Stefan Schuhbäck*** Kurosch Thuro*, Thomas Wunderlich** Otto Heunecke***, * Lehrstuhl für Ingenieurgeologie, Technische Universität München, Germany ** Lehrstuhl für Geodäsie, Technische Universität München, Germany *** Institut für Geodäsie, Universität der Bundeswehr München, Germany Brief progress report The alpEWAS project (“development and testing of an integrative 3D early warning system for al- pine instable slopes”) has been very productive although some severe difficulties had to be over- come in the course of action. Great progress has been made not only in the primary objective – the development of new measuring techniques for landslide monitoring (Time domain reflectometry (TDR), prismless robot tacheometry and low cost global navigation satellite system) and their inte- gration to a early warning system – but also es- sential new findings about the project landslide “Aggenalm” in the Sudelfeld area near Bayrisch- zell in the Bavarian Alps were gained. Due to the delayed start of the research pro- gramme in April 2007 instead of the planned be- ginning in November 2006, the time span prior to the installation of the monitoring system was not- edly reduced. Nevertheless it was possible to start with the installation in the end of August 2007. Fig. 1 Simplified project plan showing the main project phases as originally planned (with time shift due to delayed beginning in April 2007) and their actual realization. The delayed start of the research programme reduced the time span prior to the installation of the monitoring system drastically. This, combined with the problems during drilling and the onset of winter in November, led to a shift of some of the installation works to 2008.
