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.
A weak southerly wind prevailed over the piedmont plain in the BTH region in January 2013.
Orographic wind convergence zones resulted in the pollution accumulation in the piedmont plain and restrained the diffusion of pollutions; as a result, severe regional haze pollution developed.

Alfisols (soils 3, 6, and 23) developed on piedmont plains released the greatest amounts of K (mean 246 mg/kg).
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.
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.
