flooding is a big problem. Flooding is an overflowing of water onto land that is normally dry. Floods can happen during heavy rains, when ocean waves come on shore, when snow melts quickly, or when dams or levees break. Damaging flooding may happen with only a few inches of water, or it may cover a house to the rooftop.Severe flooding is caused by atmospheric conditions that lead to heavy rain or the rapid melting of snow and ice. Geography can also make an area more likely to flood. For example, areas near rivers and cities are often at risk for flash floods.Man-Made Floods Burst water heater tanks. Broken washing machine, dishwasher, or ice maker water lines. Air conditioner leaks. Overflowed toilets, sinks, or tubs. Backed up sewer systems. Frozen pipes that subsequently burst.
