AN ANALYSIS OF THE HYDRO-GEOMORPHIC ASSESSMENT OF PACHMARHI UTILISING REMOTE SENSING METHODOLOGIES

ABSTRACT

Water is one of the most essential resources of our ecology. Effective water resource management is essential for ensuring good quality, enough quantity, and availability of water due to the ongoing increase in population, rapid urbanisation, and industrialisation. Currently, water occupies the most crucial position in the human life cycle.   It is universally acknowledged that water is a finite resource on Earth; but, due to overpopulation and the rapid growth in population, the demand for water is escalating daily. It is one of the most extensively utilised resources by humanity. To examine the groundwater of a hydro-geomorphic unit, an inventory of the governing factors—namely, rock type, landform, structure, and recharge conditions—must be conducted, and their hydrogeological features appraised. The integrated amalgamation of Lithology, Landform, Structure, and Recharge conditions is referred to as ’Hydro-geomorphic units,’ characterised by three-dimensional homogenous features. The structural, geomorphological, and hydrogeological processes on the initial rock formation give rise to hydrogeomorphic units. The surface demonstration encompasses processes and their subsequent modifications. Remote sensing is the method of collecting data and information regarding all accessible characteristics inside an integrated environment. The extraction of data and mapping of geographical distribution concerning geological formations, landscapes, and hydrological conditions may be precisely conducted through the analysis of satellite images, in conjunction with secondary data and empirical ground knowledge. GIS (Geographic Information System) is usually employed alongside remote sensing for the generation of various themed maps, proving to be quite beneficial in the current study. The subject area may be more effectively studied and assessed through relevant relationships. The traditional ground survey can be prohibitively expensive and time-consuming, rendering it impractical for our investigation. The geological maps are used for gross estimation of the resource and its distribution. The data about landforms, geological structures, and recharge conditions is entirely unavailable.
