Flooding is mainly caused by heavy rainfall that exceeds the capacity of normal water courses and bodies of water.

Flood events can cause severe damage to key infrastructure such as roads and bridges, water, sewerage and electrical assets, as well as possible loss of life and economic losses in affected regions.

Social disruption also occurs, particularly when people are displaced from their homes and normal community facilities are damaged. The immediate impact can endure for weeks, or months if flood waters move or dissipate slowly.

Examples of major flood events include the 2010-11 floods that covered about one-third of Victoria. This is the worst recorded flood event for the state. This event led to a major independent review: The Review of the 2010-11 Flood Warnings and Response.
