ABSTRACT: This study finds 1D, 2D and 3D morphometric parameters of the middle-west
part of Kushtia district, Bangladesh to implement groundwater potential. For this
purpose, the SRTM (DEM) data were used to compute different parameters in GIS
environment. The values of 1D parameters like stream order, stream length and
mean bifurcation ratio was calculated as 6, 1774.72 km and 2.08 respectively.
The computed values of drainage density (0.01 - 23.06 km/km2),
stream frequency (1 - 5.64 per km2), drainage texture (0.25 - 0.70
km/km4), length of overland flow (0.02 - 45.05 km2/km),
constant of channel maintenance (0.04 -
90.04 km2/km), circularity ratio (0.39 - 0.84), form factor (0.35),
elongation ratio (0.62), relief ratio (0.00 - 1.81) and ruggedness number (0.04
- 214.72) disclose the morphometrical conditions of the study area. The results
revealed from this study on drainage morphometry can be a great assistance for
understanding the hydro-geomorphological character of the area.
