The paleotopography represents the pre-occupation topography as it may have existed about 5000 years ago.
Using maps and cross-sections of the cultural deposits from HARP, surfaces were generated to represent the interfaces of cultural layers in the mounds at Harappa. This represents the growth of the city of ancient Harappa vertically and through time.
Period 2 deposits represent a transition phase between pre urban and urban phases and exist primarily beneath Mound E.
Period 3A deposits, representing an early urban phase, exist beneath Mounds E and also show expansion onto the area beneath Mound AB. Growth in the city of Harappa is shown to be both lateral and vertical.
Period 3B and 3C deposits essentially cover the entire modeled area and represent the greatest extent of the ancient urban center. J. M. Kenoyer has developed a model describing some of the processes that contribute to the urban growth at Harappa.
Periods 4 and 5, representing a modification of cultural styles, exist at the tops of Mounds AB and E.
