How to Anticipate Flood

o anticipate food man things to do, such as' !lean the drains o debris that could clog the fow o water,

causing fooding. *redge rivers o deposits to increase the capacit o water.

/uild these alternative drainage routes 0new river channels,pipe sstems( so as to prevent an e#cessive burden on the river.

No building in the region 0area(, which became the region wherethe absorption o water.

Not to cut trees in the orest, because the orest bare would bedi-cult to absorb water, so that in case o heav rains

continuousl water can not be absorbed directl b the soil willeven erode the soil, it can also cause landslides.

Nuclear accidents or nuclear leakage is the most earedimpact beond the bene4t o nuclear energ or humans.

Nuclear meltdown occurs when the nuclear power sstemor component ailure causing the reactor core can not be

controlled and cooled so that the nuclear uel isprotected 3 which contain uranium or plutonium andradioactive 4ssion products 3 began to heat up and leak.

5 leak is considered ver serious because o the possibilitthat the reactor containment begins to ail, releasing

radioactive and to#ic elements into the atmosphere andthe environment. $rom the development standpoint, a

leak can cause severe damage to the reactor, and thepossibilit o total destruction.

Bth largest sea in the world that lies between theNorth EaDakhstan region and 8outh ADbekistan is nowreceding at ten times the original siDe due to the useo water resources without limits to the 8oviet Anionirrigation projects during the past 4t ears. 8ea with

an area o F,>>> square kilometers was once wasonce a thriving 4shing industr. However, thisindustr has been devastated b the shrinking

volume o sea water b more than our3old. Not onlthat, shrinkage o the 5ral 8ea has also resulted inlocal climate change as summer became hotter anddrier, while winter lasts longer at coldertemperatures.
