FLOODThis is the natural overflow or overbanks flow of a river. flood is a natural event that can have far reaching effects on people and the environment

This occur as a result of water-saturated the soil, which the soil cannot longer hold any additional moisture causing the water to overflown the river banks.

Cont.

Flash flood in small drainage basins can be produce by intense, brief rainfall over a small area while downstream floods in major rivers are produce by storms of long duration over a large area that saturate the soil increasing runoff from thousands of tributary basins.

Flooding magnitude and frequency are difficult to predict on many streams because of changes in land use and limited historical records. This difficulty is especially pronounced for extreme events, like 100 year floods. the probability that a 100year or greater flood will occur each year is the same regardless of when the last 100 year flood occur.

Cont.

River flooding is the most universally experienced natural hazard and flood can occur anywhere there is water which much of the USA faces the possibility of flooding.

Although, flooding causes death and damaging, it provides natural service functions like the production of fertile land for farming, benefits to the aquatic ecosystems, and maintenance of ample sediment supplies to naturally subsiding delta like the Mississippi

Land – use changes, especially urbanization, have increased flooding in small drainage basins by covering much of the ground with impervious surface such as building, parking lots, and roads thereby increasing the runoff of storm water

What causes floodflood is caused by a combination of heavy rainfall causing river / oceans to over flow their banks, and can happen at any time of the yearThey can result from other phenomena, particularly in coastal areas where inundation can be caused by a storm surge associated with a tropical cyclone, a tsunami or a high tide coinciding with higher than normal river levels.

EFFECTS OF FLOOD

Flood in Sandima-Ghana-2008This was heavy flood that overflow a whole community “Sandima” in the northern part of Ghana. the flood occur due to a heavy rainfall which overflow the riverbanks of a neighbor border of Burkina Faso.

Flood in UtahThis flood happen in Utah. Major places were affect such as roads, restaurants, supermarket chain stores an many more which people struggle to rescue their cars, and also others could not go to restaurants to eat, and buy food stuffs at stores. We need to be prepared for the unexpected so that we will survive when such dangerous floods occur.

Prepare for the unexpected

The best adjustment to flood hazards include flood insurance, flood- proofing, and floodplain regulations.

Be aware of the public awareness programs to help people clearly perceive the hazard of living in the flop prone zone

Be alert to the warning systems

Be prepare for flood Take enough food water, radio, take light, blankets

RUN! Call!

Reflective statement

The best of life is when you are safe or at a safe place all the time. Utah is prone of lot of hazards and very individual need to be prepared rather than anticipate. The are lot of natural events like landslides, flood, tsunami, earthquakes and a lot happening in Utah and across the United states. We should learn how to rescue ourselves and others in ripe currents that kill many people in the beaches, always move to the side when you are caught in ripe current and do not panic. During tsunami waves we should remember to be about 1 mile away about sea level. We should also try to use rebar in our buildings so that during earthquake or tsunami wave there would not be more damages.

Most importantly, we are expecting a quake about 7.5 miles but we don’t know when and where exactly in Utah will it occur so everyone should be prepare
