Map showing thickness of coarse-grained deposits created by scientists at the Ohio-Kentucky-Indiana Water Science Center

Volumetric model cross section through Allen, DeKalb, and Steuben Counties in Indiana created by the scientists of the Ohio-Kentucky-Indiana Water Science Center

Description: Maps showing the distribution of wells completed in glacial deposits used to create maps of hydrogeologic information and a three-dimensional volumetric model for the glacial deposits.

Existing USGS groundwater-level networks were enhanced through: 1) the addition of newly drilled deep wells that nearly reach bedrock, and 2) conversion of discrete wells to continuous, real-time wells

The Kentucky Sediment Laboratory's oven full of filtration crucibles to be dried. After baking, the crucibles are placed in a desiccator box to cool. 

Sieves determine the sand size class of sediment samples, 0.250mm and 0.063mm steel mesh are used.

The soil amendments consisted of a mixture of compost plus sand or compost plus expanded shale that were rototilled into the existing soil to depths of 4 or 6 inches. The amended soils were then topped with a compost blanket, seeded, and covered with erosion-control matting
