Ghaggar–Hakra palaeochannel
A major relict palaeochannel associated spatially with many Indus settlements. Sediment dating near Kalibangan indicates the Himalayan Sutlej had abandoned this course long before mature Harappan urbanism, so the repository does not equate it simplistically with a large active Bronze Age Himalayan river.

- Palaeochannel settlementBanawali
Banawali sits in the wider Ghaggar-Hakra settlement landscape, one of hundreds of sites strung along a relict channel that is often identified with the Sarasvati of the Rig Veda. Sediment dating near Kalibangan indicates the Himalayan Sutlej had already shifted away from this channel before the urban phase, which would mean the densest concentration of Harappan sites lay along a monsoon-fed seasonal river rather than a glacier-fed perennial one.
- Site adjacencyKalibangan
Kalibangan and Banawali both sit on the dry Ghaggar bed, and the sediment cores taken near Kalibangan indicate the Himalayan Sutlej had left this channel long before the mature Harappan city was built. That makes their water monsoon-fed and seasonal, which changes what the abandonment of these eastern towns has to be explained by.
