A Quantitative Analysis of Baitarani Drainage Basin (Odisha) Using Geographical Information System
نویسنده
چکیده
Basin morphometry is a means of numerically analysing or mathematically quantifying different aspects of a drainage basin. In the present study, morphometric analysis of the Baitarani basin has been carried out using earth observation data and geographical information system (GIS) techniques. The morphometric parameters considered for analyses include the linear, areal and relief aspects of the basin. The Baitarani basin covers an area of 10,982 sq km. It is a 6 order drainage basin with mainly dendritic drainage pattern. The mean bifurcation ratio is 4.58 indicating the basin is largely controlled by structure. The basin has medium drainage density of 0.64 per km and is elongated in shape. The length of overland flow values of the basin is 3.13, indicating high relief. The study has strengthened in understanding the hydrological, geological and geomorphological characteristics of the Baitarani basin.
