FLOOD
•FLOODING IS A DANGEROUS NATURAL PHENOMENON THAT
OCCURS DUE TO RISING WATER LEVELS IN WATER BODIES,
AND LEADING TO FLOODING OF TERRITORIES. THIS
USUALLY HAPPENS EITHER IN RAINY SEASONS OR IN
SPRING DUE TO MELTING SNOW. BUT THERE ARE OTHER
CAUSES OF FLOODING.

3. Causes of flooding

CAUSES OF FLOODING
-
-
-PROLONGED RAINS. THEY LEAD TO FLOODING OF
TERRITORIES CAUSED BY THE RIVERS COMING
OUT OF THEIR BANKS, MAINLY. THIS IS BECAUSE
THE RIVERS COLLECT WATER IN VAST
TERRITORIES. THE SEDIMENTS HAVE A STRONG
INFLUENCE ON THE WATER LEVEL IN THEM.
- MELTING OF SNOW. SPRING IN MANY REGIONS
ACCUMULATES A HUGE AMOUNT OF SNOW.
BECAUSE OF WARMING, IT MELTS, AND WATER
FLOWS CAN FLOOD EVERYTHING AROUND. TRUE,
THIS DOES NOT LEAD TO CATASTROPHIC
CONSEQUENCES.

4.

• - ACCUMULATION OF RAINFALL. DUE TO THE ACCUMULATION OF RAINFALL ON
SOME SECTIONS OF THE RIVERS THE BOTTOM IS RAISED. THIS LEADS TO A RISE
IN THE WATER LEVEL.
• - TSUNAMI. THE TSUNAMI WAVE BRINGS WITH IT A HUGE AMOUNT OF WATER,
BECAUSE OF WHICH THERE IS A FLOOD ON THE COASTS. TRUE, IT HAS A SHORT
CHARACTER.
• - DESTRUCTION OF DAMS. IN THE EVENT THAT THE DAM IS FOR SOME REASON NO
LONGER ABLE TO RESTRAIN THE PRESSURE OF THE WATER, A BREAKTHROUGH
OCCURS. THIS CAUSES A SHORT-TERM, BUT RATHER STRONG FLOODING.

5. Types of floods

TYPES OF FLOODS
-
-
HIGH WATER IS A GRADUAL, BUT RATHER
LONG RISE IN THE WATER LEVEL IN RIVERS,
CAUSED BY PRECIPITATION OR MELTING
SNOW. IT CAN LEAD TO CATASTROPHIC
CONSEQUENCES.
- FLOOD - A STRONG BUT SHORT-TERM RISE IN
THE WATER LEVEL, ALSO CAUSED BY THE
MELTING OF SNOW OR PRECIPITATION, BUT
VERY POWERFUL.

6.

- CONGESTION - BLOCKING OF THE RIVER BED, LEADING TO
FLOODING OF TERRITORIES.
- - WIND SURGE
- - SHORT-TERM, BUT STRONG FLOODING CAUSED BY THE
IMPACT OF STRONG WIND ON THE WATER SURFACE.- OTHER
SPECIES. CAUSED BY A VARIETY OF REASONS

7. Flood effects

FLOOD EFFECTS
• MOST OF THE FLOODS OCCURRING ARE RELATIVELY WEAK. THEY CAUSE MINOR
DAMAGE, DEPENDING ON THE STRENGTH OF THE PHENOMENON AND THE TERRAIN
FEATURES. THEY CAN ALSO RARELY LEAD TO PEOPLE BEING EVACUATED, ALTHOUGH THEY
USUALLY DO NOT FLOOD HOUSES. IN GENERAL, SUCH FLOODS DO NOT POSE A
PARTICULAR DANGER.
• SOMETIMES VERY SEVERE OR EVEN CATASTROPHIC FLOODS OCCUR. THEY ARE CAPABLE
OF FLOODING ENTIRE SETTLEMENTS, CAUSING ENORMOUS MATERIAL DAMAGE. IN SUCH
CASES, MASS EVACUATION OF THE POPULATION IS CARRIED OUT, BUT PEOPLE STILL
OFTEN DIE. FORTUNATELY, SUCH DANGEROUS FLOODING OCCURS RATHER RARELY.
