Morphometric Analysis Of Kharun River Basin Chhattisgarh, India

The Kharun River Basin, a significant watershed of the Sheonath River within the larger Mahanadi River Basin, represents a critical hydrological system in India that demands focused study for sustainable management. As natural resources like land, water, and soil face intense pressure due to increasing population and resource utilization, it is vital to understand the dynamics of these resources to ensure their sustainable usage and management. In this study, a range of morphometric parameters—categorized as linear, areal, and relief aspects—are analyzed to understand the spatial variations within the basin. The methodology incorporates digital elevation model (DEM) data to derive critical morphometric features, including stream order, bifurcation ratio, drainage density, stream frequency, and relief ratio, which are essential indicators of the hydrological behavior of the basin. These parameters are not only indicative of the basin's potential for water retention and flow regulation but also serve as a basis for assessing the susceptibility of the area to erosion, sediment transport, and flooding. Using SRTM (Shuttle Radar Topography Mission) data, the study delineates the Kharun River Basin’s drainage network, highlighting its hierarchical structure and identifying critical zones for conservation. Furthermore, a detailed examination of the Digital Elevation Model (DEM) of the Kharun River Basin provides insights into elevation changes, slope distribution, and watershed boundaries, which are essential for water resource management and flood mitigation planning. The aspect analysis of the basin reveals directional slopes, which impact water flow direction and soil moisture distribution, influencing land use practices and vegetation patterns. The DEM and aspect maps, along with the morphometric analysis, offer a comprehensive understanding of the basin’s hydrological framework. The outcomes of this research are expected to aid in the effective management of the Kharun River Basin’s natural resources. The findings support water catchment management by identifying potential water storage areas and areas at risk of soil erosion. Additionally, insights from the study can contribute to agricultural land-use planning by suggesting suitable zones for cultivation and advising on sustainable water usage for industrial activities. This study also addresses hazard management by identifying flood-prone areas and erosion-sensitive regions, thereby assisting policymakers in developing targeted strategies for disaster mitigation and resource conservation. Ultimately, the morphometric analysis of the Kharun River Basin provides a valuable scientific foundation for ensuring the sustainable development of the region’s natural resources
