Morphometric analysis of yesagaon drainage basin using remote sensing (RS) and geographical information system (GIS)

Abstract

Special information system i.e Remote Sensing (RS) and Geographical Information System (GIS) and Global Positioning System (GPS) has proved to be an efficient tool in delineation of drainage pattern and water resources management and its planning. GIS and image processing techniques have been adopted for the identification of morphological features and analyzing their properties of the Yesegaon watershed sub-basin area in jintur taluka of maharashtra state, India. The basin morphometric parameters such as linear aerial and relief of the river basin where determine and computed. It is 6th order drainage basin and drainage pattern mainly in sub dendritic to dendritic type. It is observed that the drainage density value is low i.e. 1.59 km/km2 which indicate the basin is highly permeable subsoil and thick vegetative cover. The circularity ratio value is 0.28 basin is reveals that the basin is strongly elongated and highly permeable homogenous geologic materials. This study will help the local people to utilize the resources for sustainable development of the basin area.
