1. Main Contributions to WB3 - ConceptsMountain RisksResearch Training NetworkTA 13Evaluate feasibility, effectiveness and performance of remedial(proactive and preventive) measures to reduce risk, assess theirenvironmental and socio- economical constraints and assess theresidual risks associated with the protective work.a. Formulate criteria for establishing warning systems and evacuation plans.b. Review, analyze and summarize in a schematized manner the characteristicsof the monitoring systems.c. Appraise the specific characteristics of monitoring systems with respect totheir potential usage with different landslide types.d. Develop simple decision support system for the selection of appropriatemitigation systems to applicable to specific landslide types.MOUNTAIN RISKS: Mid-term Meeting, Diablerets, 26-27 June 2009
