Morphometric studies using remote sensing and GIS Techniques in Bah Tehsil, Agra district, Uttar Pradesh

Morphometric analysis of four sub-watersheds namely Pidhaura, Batesar, Balapur and Pariar forming parts of Yamuna River around Bah Tahsil of Agra district have been carried out using Geocoded FCC of bands 2, 3 and 4 of IRS- 1D, LISS-III, SOI toposheets number 54 J/5 and 54 J/9 and GIS softwares — ArcGIS, Arcview and 3Dem software for preparation of DEM. The present study shows that the terrain exhibits dendritic to sub-dendritic drainage pattern, stream order ranges from third to fourth order; drainage density varies slightly and has very coarse to coarse texture in Pidhaura and Balarpur sub-watersheds and fine drainage texture in Batesar and Pariar sub-watersheds. The other parameters determined and discussed include bifurcation ratio, elongation ratio, stream frequency, infiltration number, length of overland flow and relief aspects of the watersheds. The mean bifurcation ratio depicts that the basin falls under normal basin category. The elongation ratio shows that Balarpur sub-watershed mark elongation pattern, whereas, Pidhaura, Batesar and Pariar sub-watersheds possess circular shape. The present study concludes that remote sensing techniques proved to be a competent tool in morphometric analysis of drainage basin and channel network.
