Morphometric Analysis of Dibru River Basin, Assam using Geo-Spatial Tools

Quantitative analysis of morphometric parameters helps in understanding the potential of the river basin as it helps in groundwater level management, soil properties and overall management system of the basin. It is necessary to study how fluvial landforms are formed, erosion and depositional works, and soil properties. Present paper deals with the aspects of morphometric parameters like stream order, stream number, basin area, drainage density, drainage frequency, slope with the contour interval of 10 m, basin shape, basin length and long profile etc using Arc GIS 10.1 software. We try to evaluate all the three aspects of the morphometric analysis from the SOI toposheet. Based on all the morphometric analysis progress can make about the understanding of geo-hydrological nature of the natural system and influence on the significance of shaping the basin, their runoff characteristics, infiltration, permeability, erosional power of the river etc.
