Why do floods occur frequently in Assam?
Assam is situated at the easternmost part of India. Geographically it is at the
foothills of the Himalaya.
Every year Assam experiences a huge amount of losses due to devastating flood caused by the river Brahmaputra.

Floods are one of the most common hazards in the United States.Flood effects can be local, impacting a neighborhood or community,or very large, affecting entire river basins and multiple states. However, all floods are not alike. Some floods develop slowly,sometimes over a period of days. But flash… floods can developquickly, sometimes in just a few minutes and without any visiblesigns of rain. Flash floods often have a dangerous wall of roaringwater that carries rocks, mud, and other debris and can sweep awaymost things in its path. Overland flooding occurs outside a definedriver or stream, such as when a levee is breached, but still can bedestructive. Flooding can also occur when a dam breaks, producingeffects similar to flash floods. Be aware of flood hazards no matter where you live, but especiallyif you live in a low-lying area, near water or downstream from adam. Even very small streams, gullies, creeks, culverts, drystreambeds, or low-lying ground that appear harmless in dry weathercan flood. Every state is at risk from this hazard. Floods happen when a watercourse overflows. They could be caused byrain, thaws or ice jams. Heavy Rain When it rains, water falling on the ground penetrates it. But whenthe ground already contains a lot of water, the falling rain couldnot seep through it. The water then starts flowing toward awatercourse. When it rains a lot on a region, all water flows toward the river,but this river cannot contain it; therefore, the river overflows. Thaw When spring arrives, snow and ice start to melt and the water flowstoward the river. If the temperature rises too rapidly, a lot ofwater is produced in a short time; the river overflows and a floodhappens. Ice Jam In spring, rivers thaw out and big chunks of ice detach themselvesand drift on the river. Sometimes these chunks get jammed against abridge or rocks. Consequently, these chunks of ice form a kind ofdam. When water can not flow through this dam, it tries to find analternate course to reach the riverâ¦ and, sometimes, this newcourse is a field, a road or a house basement. The Waban-Aki is a hovercraft used by the Canadian CoastGuard for ice breaking operations, which reduce flood risks. Powershovels are also used to break ice. They are known as "frogs"! Flood is the most frequent disaster in QuÃ©bec. All regions having awatercourse flowing through them could be affected. Is there awatercourse near your house? Ask your parents if your municipalityhas a flood emergency plan. What to Do During a Flood With your parents, bring upstairs all objects of the basement thatcould be damaged by water. If your family is asked to evacuate, doso immediately! The water level can rise faster than you think. Donot forget your emergency kit. Did You Know...? . In all Canadian history, the worst flood happened in theSaguenay region in 1996. In two days, the quantity of water thatfelt was the same as the quantity flowing through the Niagara fallsin four weeks! This flood was called the deluge. (MORE)
Never . A flood occurs when the volume of water in a river increases so much that the river overflows its channel.
The actual cause of a flood is the arrival of excessive rainfall inthe river headwaters. This may be exacerbated by landslides, whichimpound the waters further and give way catastrophically. Often inthe headwaters, the rain-holding capacity has been damaged byexcessive tree felling and removal of ve…getation. (MORE)
In most places it rains heavily during the monsoon season. (the time when the wind follows the seasons) There is so much of water in rivers that in many of them the water rises above the banks. It causes great damage to life, roads, property, railway lines, and houses.
They occur in a city that is lower or slanted. They can also occur where there is a lot of rainfall. In some places where there is a river, lake, or ocean, it is likely to flood. The type of land that is prone to flooding are broad and flat usually situated on the banks of a river or main waterway…. Rivers that flood are regarded in three different stages. They are:- ONE:- Water comes off the mountains, eroding the beds and banks of the river as it flows. TWO:- This type river travels through broad valleys which slows the current of the river down. If the current is slow it will transport less material down the river. THREE:- Flood-plain stage. Little if not any erosion takes place most of the material that is carried in the current is suspended and deposited to the form a flood plain. (MORE)
about every four years Tsunamis typically occur about every six years in the Pacific Ocean, and most often during March, August, and November. Although sometimes called tidal waves, tsunamis are created not by tides but by seismic movements (earthquakes), which produce chains of waves that move ac…ross the water at terrific speeds of more than 500 miles per hour.

Hurricane occur more frequently over water that is very warm. Theygenerally begin off of the west coast of Africa and travel towardthe east coast of the United States.
Hurricanes most likely occur near the equator where there are tempatures about 80 degrees in oceans.
Current estimates suggest that there are about 44 lightning strikesper second on the entire planet. Lightning strikes are particularlyfrequent in South America, South and Southeast Asia, and Africa.
it occurs when it is really rainy and it rains for a long period oftime
The floods occur in known plains when prolonged rainfall over several days, intense rainfall over a short period of time.
Because the land is low lying mainly. If the sea or rivers have more water than flood defenses can cope with then flooding will occur. For obvious reasons you don't get floods halfway up a mountainside, water will always flow downhill.
Due to the improper drainage system near to the sea coast, Mumbai is a place of frequent floods.
Firstly, it occurs due to heavy rain and storms during the monsoon season that leaves a lot of rainwater behind on land. This may in turn cause flash floods, where floods move at great speeds, causing destruction and casualties. This is partly because there is too much rainwater to be drained out of… the area using pipes and partly because of the height of the land above sea level. For example if the piece of land is below sea level, it would be greatly affected whereas those above sea level would not encounter the same situation as the water from the land will flow downwards either to a lower piece of land or a water body. Poor sewage/drainage systems may also contribute to flooding.. Secondly, it occurs due to natural disasters such as cyclones and hurricanes when they sweep across the sea or ocean, bringing a lot of water with them and as they touch land, the water is washed onto land by its powerful high-speed winds. A tsunami may also cause floods by washing seawater onto land when its storey-high waves reaches land. Earthquakes can also contribute in a way that it blocks the movement of a river, clogging up the river and causing an overflow of water in the river, flooding the lands near it. Melting of snow may also be another reason, as when the snow thaws after winter, the water might not be drained off or evaporated that quickly.. Lastly, global warming may be another cause of floods. Due to global warming, sea levels are rising as the ice caps at the north and south poles are melting significantly. Sea levels are increasing at an alarming rate of 20 + mm/year! If this continues, many more islands and lands below sea level such as Netherlands and Bangladesh may vanish under the seas forever. Currently, more than 30 small islands have been covered totally by seawater. These islands are usually small islands "stranded" in the middle of the oceans or seas, making them vulnerable to the situation. Others are submerged under sea levels due to the effects/aftermath of tsunamis. (MORE)
Flooding is the act of water levels rising to spill over to land.Where floods have occurred are any places located next to bodies ofwater.
The volume of sediment in the Huang He, mostly yellow loess , raised the river bottom so that it was higher than the surrounding lands, and the river overflowed its banks.
Allof the water that flows down a river comes from rain or melting snow.Sometimes after heavy rain or rapid snow melt,there might to much water for the river to hold.The river will then overflow its banks nad spread out across the land on either o fits channel.This is called a RIVER FLOOD.
a flood may happen at any time near a body of water, mostly around the rainy seasons, when the river or lake or any body of water overflows.
A flood occurs when there is too much water for the ground toabsorb. Floods can be caused when too much water flows into a creekand the water rises above its banks.
Earthquakes result from the collision of tectonic plates, including subducted oceanic plates or buckling continental plates. A large number occur around the Pacific Plate, in eastern Asia and the western Americas (California, Chile). They also occur in the Mediterranean, which is caught between the… African and European plates, in the Middle East, and in southern Asia where India is pushing up the Himalayas in Asia. (MORE)

Both lunar eclipses and solar eclipses occur, roughly, every 6 months or so. Solar eclipses seem rare, because they are visible only across very small paths across the Earth. Lunar eclipses only SEEM more common because they happen in the sky, and are visible from the entire night half of the Earth.… (MORE)
when there is too much water in a body of water. like the nile river

Floods can happen everywhere in the world. Because In Noah's time the whole earth was flooded. And floods can happen at anytime of the day or night.
Either the wrist or the ankle. These joints are particularly 'delicate' being constructed from many small bones rather than just two (like the shoulder).
They happen more frequently because heat from the sea is usually more available to regions that are situated near seas and oceans thats why hurricans are always common in america and northern africa
Quite simply, floods may be caused by cyclones or monsoonal rains. These weather phenomena occur only during the warmer months of the year, including summer.
Assam is a northeastern state of India. It is located in the south of the eastern Himalayas.
Yes. Levees can still burst their banks in winter, they are actually more prone to floods because the rainfall in winter is greater than in summer.
Floods occur on a regular basis. Many parts of Australia's eastern half are flood-prone, due to the numerous river systems and low plains throughout the region. The northern and eastern coasts are also prone to summer cyclones (which bring heavy rains) and seasonal monsoonal rains. These rains can s…end large amounts of water across the northern plains, through Queensland's "channel country", which floods huge areas of land in north western Queensland. Another particularly flood-prone region is the Hunter Valley in New South Wales. The floods that occurred in December 2010 and January 2011 were unusually severe. These types of floods tend to only coincide with a "La Nina" event. (MORE)

The floods affecting Australia this summer (2010-2011) began in parts of Queensland as early as December 10 . With many properties already under threat, conditions worsened considerably when a widespread cyclone system hit northern Queensland on Christmas Day, dumping huge amounts of rainfall right… across the state. The floods really began to be felt just after Christmas as major centres like Rockhampton and Bundaberg were inundated. The floods then hit many other towns, until finally on 11 January , the Brisbane River actually began to break its banks. With the continuation of an unusually heavy rainfall pattern, courtesy of La Nina, there is no immediate end in sight. Cyclones have continued to dog the Queensland coast, bringing flooding rains with them. (MORE)

it's less frequent in the winter and fall and more grequent in the spring and summer in fact over 1000 tornadoes are confirmed every year and a thousand on average
There are several hundred avalanches a season in mountains worldwide, but most do not affect people. On the Alps and similar ranges, there are a few dozen fatalities per year.
It can happen anywhere if there is heavy amouts of rain fall or a river that is close by that could to flooding
well, a lot of things get filled with water, cars and homes are destroyed, people freak out, some people die from the flood itself, or just from being a moron and trying to swim in the flood water. news channel cover it and everything. just things like that
Yes, because the lakes that were once in one place are no longer there anymore. We built over them as if they never existed. The rain that comes down has no low land to go to, but into the houses we built. If the lakes were still there, we would have none of this flooding. We are not only creating a… new world, but we are destroying the world we never created. (MORE)
Because the land in these areas is particularly low lying in comparison to the local water level, therefore any increase in that level because of rain, snowmelt, stormsurge, etc more easily floods the surrounding land.
No. Thunderstorms require relatively warm, moist air, which is hardto come by in the winter.
Gonorrhea frequently occurs in connection with chlamydia. About 30% of patients with gonorrhea also have chlamydia.
The heavy rainfall on the higher lands and the lack of dams on thelower lands is the cause of flood in Assam. It affects the economyas people are displaced from the places that they work and eat.
Bangladesh has very low lying land, in some parts it is only 1metre above sea level. Its land is quite marshy and in the summer,when snow on the Himalayas melts, it sends lots of water into themain rivers in Bangladesh's main rivers, Ganges and Brahmaputra.Those are the physical reasons I can think …of. Hope that answersyour question :) (MORE)
It is not known. About 1,800 tornadoes are recorded worldwide in anaverage year, most of them in the U.S. but the actual number oftornadoes is probably several times higher. It is likely thatthousands of tornadoes occurring in poor countries or remote areasare never recorded.
It is in a seismically active area, being near the edge of thetectonic plate that India is on and which is pushing into the restof Asia.
