Geography
The Deukhuri Valley (देउखुरी उपत्यका) is southeast of the Dang Valley and extends about 60 km in WNW-ESE direction with a maximum width of 20 km. It forms a nearly 600 km2 plain within a drainage basin of 6100 km2. The valley is drained by the West Rapti River. It emerges from its gorge through the Mahabharat Range and flows WNW along the axis of the Siwalik Range between the Dundwa Range along the India border and the Dang subrange to the north. It flows 100 km in this direction until the Dundwas fall away near Banke, and the river can resume flowing SE toward the Ganges.

The Mahendra Highway passes through the Deukhuri Valley. Valley is settled by Tharu people, and used as winter pasture by Kham Magar from the hills.
