Assessing of feasible Independent Protection Layers (IPLs) using Layer of Protection Analysis (LOPA) for flood emergency risk management

Layer Protection Analysis (LOPA) which is a risk-based approach was chosen for this purpose to evaluate the frequency and consequence to help risk decision makers for emergency risk management. Many factors have been considered in order to complete this task to achieve acceptable flood prevention an...
