This paper discusses the application of Remote Sensing and GIS for the development of Ground Water prospects in hard rock terrain areas and the water resources plan at micro level for appropriate management and monitoring in rain-fed regions of Ranchi district in the state of Jharkhand. In the present study the morphometric analysis of the study area (the Jumar river basin at Bariyatu region of Ranchi district) is carried out using Remote Sensing data and the relevant Toposheet of Survey of India. IRS -1C and 1D, LISS-III data of three different years namely 1997, 1998 and 2004 including PAN data merged with LISS-III image is used in the analysis and study. ARC GIS 8.3 packages and ERDAS Imagine 8.5 software has been used. Soil data has been collected from different organizations. The rainfall data has been taken from metrological department, IGWD, Government of Jharkhand and the runoff potential has been determined using soil conservation service method. The data regarding the water level in pre-monsoon and post monsoon seasons has been collected from IGWD Government of Jharkhand. In addition DEM and TIN model were generated for site selection of check dam, nala bandh and small reservoir for rain water harvesting. Ranchi district is physiographically a plateau region and average elevation is about 600 meters above mean sea level.
Geomorphologically it consists of shallow weathered pediment, Structural Hill and Residual Hill overlaid by red and yellow soil with poor fertility and low water capacity. The soil of upland consists mainly minor sandy loam associated yellowish soil. Geologically speaking Ranchi region is occupied by granite and granite gneiss rocks overlaid by red/literate soil. Other metamorphic rocks are Schist and Phyllite intruded by vein of Pegmatite Quartz. In the present study we have integrated various socio-economic data to formulate and come out with an action plan for rain water harvesting. In urban region the suggestion for roof rain water harvesting is beneficial for storage of potential drinking water. Ground water is very precious gift provided by HIM to all of us and we must preserve and conserve it for generations to come.
