An examination of the city's settlement remains which changed with the onset of urban growth and development in Harappa.
From the article
"Excavations on two of the major mounds at Harappa have revealed traces of an early settlement, a transitional phase of development, and several phases of full urban and post-urban occupation. Although there is a continuity of occupation, evidence for settlement growth and changes in organization reveal a dynamic process of city development. The segregation of specific crafts and occupations, the availability of new and exotic raw materials, the construction of massive perimeter walls and entrances, and the maintenance of civic structures provide a new perspective on the nature of an Indus city. A preliminary model is presented for the development of Harappa as a city in the wider context of the Indus Tradition."
