What caused the decline of the Indus Valley civilisation?
More than the enviornmental factors, it is now believed that the main cause that led to the decline of the Indus valley civilization was the violent arrival of the Indo- Aryans.
The crucial factor may have been the disappearance of substantial portions of the Ghaggar-Hakra river system. A tectonic event may have diverted the system's sources toward the Ganges Plain, though there is some uncertainty about the date of this event. Such a statement may seem dubious if one does not realize that the transition between the Indus and Gangetic plains amounts to a matter of inches, and is all but imperceptible. The region in which the river's waters formerly arose is known to be geologically active, and there is evidence of major tectonic events at the time the Indus civilization collapsed

hello Vagbond ,
thanks for posting an alernate view, but we gotto acknowledge the fact that an advanced civilization just doesnt go to dust like that or worse shift down south during the course of history
It is true that there is no archaeological evidence of the
movement of Indo-Aryan speaking people into the subcontinent, but
that is not an argument against such a movement.
Many major
migrations that are historically documented have left no
particular traces in the historical record, such as:
-- The migration of Goths and Huns into Western Europe, destroying
the Roman Empire
They do not establish that any invasion happened, but they do give the lie to any argument that says that it could never have happened. plus there is genetic evidence to prove this
