Abstract

The supply of groundwater is not unlimited and therefore its use should be properly planned based on the understanding of the groundwater system’s behavior in order to ensure its sustainable use. An attempt has been made in the present study to select and delineate different potential groundwater zones for the need of proper assessment of groundwater availability in the Ukmeh river watershed area which belongs to the upper Vindhyan region. In order to prepare various thematic maps viz. lithological, slope, lineament density, drainage density maps satellite IRS-IC LISS III, SRTM data, and Landsat TM digital were used. The weightage has been given to the thematic maps based on their relative contribution towards groundwater potentiality. In order to compute groundwater potential index, all the thematic maps with each other were registered. This was made with the help of ground control points and proper step by step integrated approach applying normalized aggregated method in GIS. So on the basis of final weight map and their ranking, groundwater potential zones were delineated. It was observed that groundwater potential zones in the present area of discussion can successfully be observed with the above integrated approach method. The potential zones are categorised into five parts namely very poor, poor, moderate, good and very good. The economic target areas in the resultant map have been marked by the very good to moderate potential zones. The majority of the study area found to be dominated by good to moderate prospect zone potentiality. The present technique used to delineate groundwater potential zones has been done in different areas but this area has not been studied so far so is now been first studied for groundwater potentiality using the technique.

Abstract

Objectives: Morphometry is a measurement and mathematical analysis of landforms. The main objective of the study is to calculate the morphometric parameters of the Bagain river basin. Methods/Statistical Analysis: Remote Sensing (RS), Geographical Information System (GIS) and Global Positioning System (GPS) proved to be an efficient tool in our modern geographical and geological studies that are been used in the study. Basin morphometry shows numerical analysis or mathematical quantification of different aspects of a drainage basin. In this study Bagain river basin has been selected for morphometric characterization which is a tributary of river Yamuna. The morphometric analysis includes aspects as linear, areal and relief. Findings: The region is covered with high altitude Vindhyan hills. There is a large number of drainage systems originated from south and goes to north and downpours in the Yamuna River. The method applied to the river basin gave a recent calculation of the morphometric parameters of the region. Application/Improvements: The present study gives an account of information about drainage pattern, stream behaviour and morphometric setting of drainage within the network helping for watershed management.
