The Engineering Response to Flooding 1. Inland Flooding – Ohio River
What do we do? 1.Understand the underlying geology 2.Calculate probability of an event 3.Estimate the severity of possible effects 4.Establish risk to populations & environment
What do we do? 5. Reducing the risk A.Avoidance B.Building codes C.Evacuation plans D.Removal of endangered structures E.Protective engineering
