Others investigated the physiological impacts, including health-related quality of life, acute myocardial infarction, chronic diseases, and malnutrition.

What is the cause and effect of flash flood?

Flash flooding can also be caused by extensive rainfall released by hurricanes and other tropical storms, as well as the sudden thawing effect of ice dams. Human activities can also cause flash floods to occur. When dams fail, a large quantity of water can be released and destroy everything in its path.

BenefitsFlood storage and erosion control–offer a broad area for streams and rivers to spread out and accommodate temporary storage of flood water, reducing flood peaks and erosion potential.Water quality maintenance – reducing sediment loads, filtering nutrients and impurities, and moderating water temperature.More items…

What causes a river to flood?

Rivers and creeks flood when pulses of rainfall and/or snowmelt move downstream. This causes water to overtop the channel’s banks and spill onto the neighboring floodplain. A natural river channel is shaped by the amount of water and sediment that travels through it.
