Hilly sand plain occurs at the foot of the Sur Ghar hills and is separated from the piedmont plain by the Paharpur canal .
The hydro- geological results assessments reveal that the central part of the piedmont plain consists of sand layers with alternate clay deposit.

The soils have developed on different physiographic units including alluvial plains, piedmont plains, plateaux, and lowlands.
Soil geomorphological units observed in the study area were recent alluvial fans in the foothills of Marwat Range, recent piedmont plain characterized by sandy outwash derived from Bhittani and Marwat Ranges in north-northwest, and from Cretaceous shales of Sulaiman Range in the west.
Soil drainage varies from excessively drained in the recent piedmont plains to moderately drained in other units.
The region, sometimes referred to as the Piedmont Plain
, extends from southeastern Pennsylvania south through Maryland and Virginia into northern North Carolina.
(VLIp): land higher than 250 m (820 ft) above sea level, making up the distal and proximal piedmont of the hill system.
