Characterisation of key risk scenarios

Based on the identification of the key risk combinations in task 31 the possible parametrical variations of key input variables within the six focused model scenarios will be characterised These values will be based on an assessment of the different hydrogeochemicalmechanical facies characteristics expected within the seven different shale gas basins already identified within Europe WP2 D23 This ensures that events and processes occurring at different sites can be compared and contrasted against a common frame of reference providing the basis for the construction of a structured knowledge base and generic risk assessment
