Application of GIS and remote sensing in morphometric analysis of river basin at the south-western part of great Ganges delta, Bangladesh

Abstract Analysing the morphometric parameters is most expedient and parsimonious way of representing hydrologic physiographic attributes river basins. The present study attempts to measure for assessing understanding morphological, hydrological, properties south-western part Ganges delta. Parameters were analysed from Shuttle Radar Topography Mission's (SRTM) maps total eight linear, six areal, relief, five drainage texture have taken with hypsometric analysis four major rivers two tributary values linear parameter denote that streams (82%) fall in first order, other orders homogeneous underline materials. aerial represent low peak discharge upper region less vulnerable flood. relief show entire basin has surface runoff they are erosional (slope < 3.97°). density indicates coarser nature circularity ratio (0.08) represents elongated shape. southern portion a greater flood potential index (0.49) shows mature stage formation. These results would be helpful reckoning watersheds management environmental planning ecological sustainable development.
