| Popis: | Basin-wise DEM-based Automated Morphometry (BaDAM) toolbox, an automated solution for drainage basin morphometric analysis, is presented in this paper. The toolbox, being scripted in Python, can be easily integrated with ArcGIS 10.0 version, and customizations can be implemented effortlessly. The BaDAM toolbox has been tested for computation of morphometric attributes of a tropical river basin in Kerala (India) using SRTM DEM (30 m), and the analysis was carried out successfully with less time complexity and with significant efficiency. Further, the results of the DEM-based morphometric analysis generated by the toolbox showed good agreement with the results of a previous study using SRTM data for the same river basin. It is suggested that the toolbox, which takes care of most of the inherent limitations of the existing programs/tools, can be used for DEM-based basin morphometric analysis for generating comparatively quicker and accurate results. |
