They are caused by too much rain, hurricanes, breaking of dams, etc. This is one of two quizzes on flooding and it focusses in particular on the causes and the effects of floods. The impacts varied between urban and rural areas and these are described separately. Some recent research has considered the criteria for safe evacuation of individuals in flooded areas. Debris modification of channel geometry is common when heavy flows move uprooted woody vegetation and flood-damaged structures and vehicles, including boats and equipment. Often lasting longer and impacting larger areas, floods tend to be much more costly than other events, both in financial terms and lost lives.
Coastal regions can also be affected by flooding. As earth's temperature increases, glacial ice recedes. They are often caused by , but overflowing lakes and seas can also cause flooding.

The to seek medical attention or treat open woulds right away. Loose soil, rocks, and landscape can be dramatically altered, leaving behind a rugged, changed terrain. The negative effects of floodwaters on coastal marine environments are mainly due to the introduction of excess sediment and nutrients, and pollutants such as chemicals, heavy metals and debris. Effective flood channel geometry may be changed by growth of vegetation, accumulation of ice or debris, or construction of bridges, buildings, or levees within the flood channel. Retrieved 13 January 2016 — via YouTube. Preventing Erosion and Maintaining Land Mass Elevation Soil deposited by floodwaters prevents erosion and helps maintain the elevation of land masses above sea level.
