MORPHOMETRIC ANALYSIS OF PAGLA RIVER BASIN, EASTERN INDIA USING GEOGRAPHICAL INFORMATION SYSTEM (GIS)

Krishanu Datta, Krishnendu Gupta

Abstract :

A Morphometric analysis of Pagla river basin has been carried out using Geographical Information System ( GIS ). Morphometric parameters have been evaluated from four perspectives : drainage network, basin geometry, drainage texture and relief characteristics. The Pagla river basin covers an area of 562.10 sq.km. The study area has been designated as a fifth order basin and lower order streams mostly dominate the basin with drainage density value of 0.98 km/sq.km. The elongation ratio of the basin is 0.49 which indicates that the study area is elongated with low relief and gentle slope. The results of this study provide information on drainage morphometry that can help to understand the hydrogeomorphological character of the basin.
