Flooding
* Is a common occurrence with hurricanes.
* allows water to saturate the floodplain and raise the water table.
* also decreases fertilizer efficiency, and interferes with pest and disease control
  - replenishes underground water sources for the forests
* are natural hazards.
* becomes a problem with development because paved land allows water to run off more quickly.
* can affect areas hundreds of miles from the coast
  - the physiochemistry of wetlands in various ways
  - also cause silting
* can also occur in low areas and in areas where storm drains are blocked
  - the fall, from hurricanes and tropical storms
  - when a dam breaks, producing effects similar to flash floods
  - transport nonnative aquatic and marsh species to new regions
  - be a major problem in areas with higher rainfall
  - begin before a hurricane nears land
  - cause anaerobic conditions
* can contaminate food with silt, raw sewage, oil or chemical waste
  - local water supplies and lead to local increases in diarrheal diseases
  - damage plants in many ways
  - inundate roadways and damage or undermine bridges
  - modify soil characteristics in many ways
* can occur almost anywhere, but it occurs least often in desert areas
  - because water-drainage patterns are changed
  - suddenly at any time of day, during any month of the year
  - when a house is slightly damaged and the water line is cut
  - result when heavy snowfalls melt or ice jams block waterways
  - wash vegetation and soil along waterways
* carries an abnormally large threat of the spread of disease.
* caused by beaver dams can seriously damage peatlands
  - convective storms tends to localized unless the storms fail to move quickly
* causes turbidity and siltation as it scours river banks and bottoms.
* changes the ecology of the soil, causing anaerobic organisms to replace aerobic organisms
  - physical, chemical and microbiological properties of a soil
* common cause of nest failure.
* creates anaerobic conditions and increases the accumulation of organic matter
  - high mortality
* critical factor in the disease cycle.
* destroys life, property and causes loss of money.
* fact of life in Bangladesh.
* generally occurs during spring runoff or during periods of high rainfall in the fall.
* is India's major natural hazard
  - almost always a natural occurrence
* is also a consequence of other disasters
  - distribution problem in that some areas receive more water than they can handle
  - regular seasonal phenomenon in Northern Australia
* is an important natural process which contributes to building and shaping the landscape
  - overflowing of water onto land that is normally dry
  - brought about by intense precipitation
  - but one of the many injurious factors trees face over the course of their lives
  - by far the most prevalent, occurring to some degree in every State in the nation
* is caused by a number of factors
  - in a variety of ways
  - common in both spring and autumn
  - commonplace in the wake of a storm, threatening human life and property
  - excess water
  - experienced in every region of the earth where there are rivers
  - for brief periods late in winter and early in spring
  - likely to create greater risk of contagious water-borne diseases, malaria and diarrhoea
* is one of the most dangerous consequences of a hurricane
  - results of erosion
  - symptom of global warming
  - way to putting water in the bank, figuratively and literally
  - part of life along the middle reaches of the Yangtze River
  - particularly dangerous because it often leads to landslides or mudslides
  - probably the most common natural disaster
  - ranked number one in weather related deaths
  - the America's most frequent and destructive natural disaster
* is the leading cause of death associated with severe weather
  - weather related deaths nationwide
* is the leading cause of weather-related death in the United States
  - death nationwide
* is the most common natural disaster
  - of all natural hazards
  - frequent cause of death during a hurricane
  - number one weather killer in the United States
  - result of snow melt
  - worse in areas where a forest has been cut down
* large amount of text displayed in a short time.
* leads to a deprivation of oxygen in plants.
* major natural hazard that can result from human activities, as in dam failure.
* natural part of a river's cycle
* occurs in both natural and developed watersheds
  - winter and summer
  - low-lying areas of South Carolina such as river basins and coastal areas
  - the later stages of plant growth and can last for several months
  - primarily in the winter and spring
* occurs when a watercourse is unable to convey the quantity of runoff flowing downstream
  - the volume of water exceeds the capacity of the channel
  - water falling from the sky has nowhere to go
* often accompanies hurricanes
  - occurs during the winter months
* produced by hurricanes and tropical storms can reach hundreds of miles inland.
* seems to play an important role in reseeding burnt areas with trees.
* significant severe weather hazard in Illinois.
* sometimes occurs during the annual spring thaw.
* stress that crop plants frequently encounter and results in huge economic losses.
* usually causes more fatalities each year than tornadoes
  - occurs after spring rains, heavy storms, or thawing
* year-round occurrence.
