AbstractThe Satpura region of Central India is characterized by hilly mountainous terrain and plateau country. The recent drilling of over 500 tube wells in the study area by the Evangelical Lutheran Church (E.L.C.) Water Development Project provided the data base for this study. Geologically, the area is underlain by crystalline rocks, basalts, and sandstones. Ground water flow systems are of the local and intermediate type. Well data such as yield, depth, depth of overburden, and aquifer depth were analyzed statistically according to rock type and topography. Wells drilled in valleys and flat uplands were the most productive and average well yields in crystalline rocks (23.9 gpm) were greater than In basalts (17.3 gpm) and sandstones (9.7 gpm). Linear and non-linear relationships among well parameters were analyzed to determine factors affecting well yields. Topographic location and fracturing were considered to be the predominant factors affecting well yields in the crystalline rocks. Well yield and specific capacity results were compared to results from areas of similar geology. Both step-drawdown and constant rate pumping tests were conducted on production wells. Step-test results indicated that well losses are significant in a number of wells tested and appear to be related to non-Darcian flow in the aquifer adjacent to the well. Constant rate pumping test results were analyzed by the Jacob-Cooper approximation to the Theis equation, and recovery data were analyzed by the residual drawdown method. Transmissivities in all three rock types ranged over two orders of magnitude, from 10² to 10⁴
