Why were floods a welcome event for early indus valley people?

Floods were a welcome event for early Indus Valley people because they brought nutrient-rich silt that enhanced soil fertility, making agricultural practices more productive. The annual inundation of rivers like the Indus provided a reliable water source for irrigation, supporting the growth of crops such as wheat and barley. This agricultural abundance allowed for the development of settled communities and the rise of complex societies in the region. Thus, floods played a crucial role in sustaining the economy and culture of the Indus Valley civilization.
