Wayne W. Lapham
1981, Water-Resources Investigations Report 81-35
The ground-water resources of the White River basin in and near Madison County, Indiana, were investigated by mapping the aquifers, estimating their hydraulic properties, determining the distribution of potentiometric head in the aquifers, and estimating some of the components of the ground-water budget from data collected in the field. This...
