Aquifer Characterization and Drought Assessment Rock River Alluvial Aquifer

This investigation evaluated groundwater resources of the alluvial aquifer located adjacent to the ock River. Recent drought conditions prompted this study and can have a dramatic affect on groundwater resources. The primary objective of this study was to evaluate the aquifer to aid in future water supply development. Existing geologic information combined with geophysical surveys and drilling were compiled to better understand the extent and thicknesses of coarse grained alluvium. Several hydrogeologic parameters were gathered to estimate well potential in the aquifer. The study can be referenced when considering future development or well field expansion.https://ir.uiowa.edu/igs_wrir/1011/thumbnail.jp
