Haryana has five natural topographic divisions, from sand dunes to the Shiwaliks
Background
The Haryana Government portal divides the State into five natural topographic divisions.
They are the Bagar and undulating sandy plains, the Alluvial Plain (Ghaggar-Yamuna Plain), the Aravali outliers, the Shiwaliks and the Foot Hill Zone.
The Bagar lies in parts of Sirsa, Hisar and Bhiwani districts, in sand dunes adjacent to the Thar desert on about 11 per cent of the total area of the State.
The alluvial plain forms the water divide between the Ganga and the Indus river systems.
Within it lie the flood plains known as Khadar of Yamuna, Nali of Ghaggar and Bet of Markanda.
In plain words
Bagar Bagar (sandy plain of south-western Haryana) — The local name for the sand-dune region of south-western Haryana.
