Morphometric Analysis of Jiya Dhol River Basin

Basin morphometry is an important means of understanding a drainage basin using mathematically derived parameters. In the present study basin morphometry has been analyzed under three broad aspects and they are the linear, areal and relief aspects. Within these aspects there are many parameters which are being determined by using mathematical formula on data derived from Toposheets of the study area. It is covering an area of 1094.93 sq. km. The drainage pattern of the upper section of the basin is trellis pattern and the lower section is anabranching. Floods are common phenomena of the lower section of this basin. This paper explains the role of basin morphometry specially the linear and relief aspect in providing condition for occurrence of flash floods in the lower section of Jiya Dhol River basin.
