Abstract
River basin analysis is highly useful to understand the hydrological dynamics with concerning the topography. The morphometric properties of a drainage basin will help in describing the quantitative attributes of the landscape. A digital representation of topography enables the computation of more complex morphometric parameters with automated refinement. Digital Elevation Models (DEM) represents the topography of Earth in the form of digital imagery. In this article DEM has been used to compute the linear aspects and areal aspects of the Brahmaputra basin falling in the Indian sub-continent. Linear aspects which include stream characteristics like stream order, stream length, mean stream length ratio, bifurcation ratio have been reported thought this article. The areal aspects of river basin like drainage density, stream frequency, form factor, and circulatory ratio have been investigated and these parameters have been used to analyse the river basin characteristics. Geospatial data and technologies prove to be very efficient in analysing the basin’s behaviour.
Key Words: Brahmaputra river, Digital elevation model, Drainage characteristics, Morphometry
