The technical concept within the Integrative Landslide Early Warning System (ILEWS)

摘要

This paper describes the technical instrumentation used by the ILEWS Project to build up alandslide early warning system. Measurements of landslide movement and soil-water-status are conducted andintegrated into a physically-based slope stability model for continuous calculation of slope stability and intosurface-analysis early warning model. Beside the technical early warning system the ILEWS Project followsan integrative approach,also including social scientists,spatial planners and historians. The overall goal is toprovide a complete warning chain,including in-situ measurements described in this contribution,data handling,automated but supervised analysis,warning and consequent communication and decision making.
