Flood Example: There are two sides to this risk: the probability of flooding, and the consequences that would follow. An area could have a high probability of flooding but minimal consequences because the area subject to flooding is forested and contains no infrastructure or people, so the risk is low. Conversely, a highly urbanized community that has a moderate or low probability of flooding would be considered high risk, because the consequences of a flood in that location (loss of life, livelihood, property, health and human suffering) would be very high. We manage the probability side of risk with levees and other structures to control flooding. We manage the consequences side by making land-use decisions that keep infrastructure out of harm's way, or by reducing the consequences to existing infrastructure using a multitude of floodplain management methods.
