Morphometric Analysis of Ur Basin of Tikamgarh District, Madhya Pradesh by Using GeoSpatial Technique

Abstract

Geospatial technique is a integration of Remote Sensing (RS),Geographic Information System (GIS)and GPS Tools are most appropriate, cost effective and quick technique for estimation of morphometric properties over traditional methods. Geographical Information System (GIS) methods are now-a-days in usage for evaluating several terrain and morphometric parameters of the drainage basins. It is also well observed that remote sensing satellite data is emerging as the most effective, time saving and accurate technique for morphometric analysis of a basin. This technique is found relevant for the extraction of Ur river basin and its stream networks through SRTM (Shuttle Radar Topography Mission (DEM) in con-junction with remote sensing satellite data (Landsat 8, 2017 and georeferenced survey of Indian toposheet). Ur Basin is a tributaries of Dhasan River has been selected for morphometric analysis. The morphometric analysis of basin has been carried out using GIS softwares.The drainage network of Ur Basin was delineated using remote sensing data. Morpho-metric parameters viz; stream order, stream length, bifurcation ratio, drainage density, stream frequency, form factor, circulatory ratio, etc., are calculated. The drainage area of the basin is 1500.27 km2 and shows sub-dendritic to dendritic drainage pattern. The stream order of the basin is mainly controlled by physiographic and lithological conditions of the area. The study area is designated as 7 th order basin with the drainage density value being as 1.72 km/km2 . The increase in stream length ratio from lower to higher order shows that the study area has reached a mature geomorphic stage
