Abstract

This study examines the morphometric characteristics and drainage anomalies of the Kanchi River Basin, which is a tributary of the Subarnarekha River located in Jharkhand, India. SRTM DEM data alongside ArcGIS 10.3.1 were utilized to outline the drainage system and conduct morphometric evaluations. The recorded drainage density stands at 1.13 km/km², the stream frequency at 0.97 streams/km², and the relative relief at 276.66 m. The anomalies in DD range from –1.23 to –2.35 km/km², while the anomalies in stream frequency range from –1.21 to –4.77stream/km². The basin is elongated, moderately dissection, and is influenced by the underlying structure. Tectonic activity and variations in lithology have a significant impact on how drainage anomalies are spatially distributed. The combination of DEM and GIS has proven effective for geomorphological studies, assisting in watershed management and planning for land use.
