The Indus River
Two resons historians use to explain the downfall of Indus Valley cities
it is located in Karachi
Floods occur when the river flows higher then its regular base. They bring disaster to humans, and fertile soil, making crops grow better.
Tectonic shifts caused a major river, the Sarasvati/Ghaggar river, to dry up. There were also changes in the monsoon rains which caused floods followed by droughts, so that most of the people left.
To help survive during floods .
There are various opinions as to what happened to the Indus valley civilization. Probably them most held is that climate change (disappearance of the monsoons) resulted in a migration to the east but in smaller more isolated towns.
The advantages of living in the Indus Valley Civilization; there was running water, drainage systems, people could read and write, there was trade with other cultures, there was a government, and domestic animals such as cattle, and crops such as rice and cotton. The disadvantages of living in the Indus Valley Civilization; monsoons caused floods, and in the dry season the people and animals were too hot and hungry and thirsty.
The Aryans (Vedic people) overthrew the stone forts of the Dasyu. If you refer to the Indus Valley Civilization people, no one conquered them, they left Sindh because of floods and drought.
rivers, mountains/hills, floods and maybe climate change
There were monsoon rains that caused floods which damaged houses and other buildings. During the dry season, people and animals went hungry and thirsty, and crops dried up.
It came from Indus valley!! and from the area near indus valley
Indus valley Civilization fell due to natural calamities such as floods, earthquakes etc. some scientists believe that the attack of foreign tribes caused it to fall attack of aryaans ( another civilization ) could be the cause but still it is not found out these are just guesses
The Indus Valley Civilisation grew steadily and prospered for about 1000 years. Around 1500 BCE, the Indus Valley Civilisation rapidly declined. It ended with Mohenjo-Daro being abandoned around 1200BCE and Harappa soon after. Archaeological evidence, such as signs of constant rebuilding of walls and foundation of houses, suggests that floods could have caused the decline of the Indus Valley Civilisation. These woluld also have destroyed the irrigation systems that the people depended on for their farming. Some scholars think that the floods might have bred mosquitoes which led to outbreaks of malaria. Whatever the reason, the decline was almost certainly speeded up by the invasion of the Indus Valley by a group of people called the Aryans\ (Adapted from The Living Past History Of Ancient India,China and Southeastasia 2nd edition)
The Indus Valley civilization went into a decline caused in part by changes in the monsoon rains which resulted in floods and drought. Also the Ghaggar river dried up and an earthquake destroyed the port city of Dwarka, making trade with other regions more difficult.
