M1-07: INTEGRATED RISK ASSESSMENT TECHNIQUES Key Objectives: –Familiarization with the tools and techniques available to complete an integrated hazard and disaster risk assessment –To look ahead to concerns of M2 : reporting on and mapping the risks

INTEGRATED RISK ASSESSMENT Collection, analysis, and display of hazard & risk data using a common spatial framework –Multiple parameters/causative factors for a single hazard type –Need to integrate the contribution of individual parameters –Same area may face different hazards –May require to integrate the assessment of different hazard/vulnerabilities/risks for the same area Development of a database system

ANALYSIS METHODS Probabilistic Deterministic Informal & Subjective

TECHNIQUES Identify/survey key parameters for each hazard (such as slope angle, soil/rock types & thickness, orientation of rock-beds) Identify the relative contribution of various factors Map the individual factors - depict on copies of base map to prepare hazard map (by overlay) Overlay different Hazard Maps for the same area

TECHNIQUES New technologies help to collect & manage increasingly complex data (satellite technology, GPS, scanners/digitizers, software) Digital technologies permit increasingly complex analyses, database generation, & manipulation But Ensure that: –Correct conceptual model –Data is complete, consistent, relevant & organized
