Risk analysis and evaluation


For each event identified in step 3, in this step, the estimation of risk begins with the assessment of event likelihood and consequences, and recording of the reasoning behind the options taken. Each event can have consequences in several dimensions and those need to be fully considered and the estimation process fully described.

Once event’s likelihood and consequences are estimated, the level of risk for each event can be determined using the selected method. The final task of risk assessment is the evaluation of each event, by comparing the risk level with the risk criteria defined in step 1.

This step provides a screening of risks. Detailed analysis can be necessary to improve understanding of higher priority risks as well as to analyse and select risk reduction measures.

Each stakeholder responsible for managing a water system should aggregate and report to the team the results from their internal risk assessment, provided that these are relevant for the water cycle level. Special attention should be given to SSP boundary issues.
