Abstract
Groundwater is one of the major available fresh water in our country. Due to its over exploitation, fulfilling the demands for domestic, agricultural and industrial purpose, groundwater level is falling very rapidly day by day especially during summer season in arid and semi-arid regions, leading to water scarcity problems. The present paper covers study and analysis of groundwater flow in Upper Seonath basin, a sub basin of Mahanadi river in Chhattisgarh by developing a groundwater flow model. Study area extend from 20°16N to 22°41N latitude 80°25E to82°35E longitude comprises of two district of Chhattisgarh namely Durg and Rajnandgaon having a total geographical spread of 7292 sq.km. From the field observation it was found that there is a considerable rate of change in water table, especially during the summer season in the past years. This fluctuation in water table is generally caused due to land use/land cover change, over exploitation in unscientific manner. Therefore it becomes necessary to study the groundwater before its exploitation so that a proper balance is maintained between the recharge and extraction. In this study Groundwater flow simulation model has been developed using Visual MODFLOW package. Simulation results help in fetching information about the hydraulic head, drawdown, flow direction etc. The graphs and maps generated using the Visual MODFLOW tool helps us in predicting the groundwater flow condition.
