MORPHOMETRIC ANALYSIS OF BAGHLAN PROVINCE FOR AMU RIVER BASIN IN AFGHANISTAN USING REMOTE SENSING AND GISSafiullah Sherzad and Tharavathy N.C.Abstract Baghlan province is located in north of Kabul and surrounded by Bamyan, Kunduz,Parwan, Takhar, and Samangan provinces. It lies on the core route to the north and North-eastern regions of Afghanistan, which in terms of geographical location (coordinates) 29 degrees and 31 minutes north latitude and 58 degrees and 48 minutes east longitude, it is located 230 km from Kabul along the Kabul-Mazar highway; In the past, this province had 12 districts, which has now been raised to 15 districts, but in our current study, it will discuss 12 districts, which are the same 15 districts; 15 districts were canceled because there were no changes in the calculations of morphometric analysis. The different morphometric analysis explains the physical appearance of the watershed, which are suitable for the areas of land development, soil protection, topography rise, and soil erosion (Horton, 1945). This study discloses that DEM and GIS method in calculating morphometric drainage parameters and their effect on hydrological features at the watershed level is suitable than the conservative methods. The complete basin means bifurcation ratio (Rb) is 2.43, which shows that the drainage pattern is partial by geographical structure. Doshi and Khinjan districts have a high elongation ratio (Re), Ruggedness number (Rn), basin relief (Bh). It shows that peak discharges and erosion are high in these basins. This study is very beneficial for applying rainfall aggregation and watershed management. |
