Experimental Limestone Dissolution And Changes In Multiscale Structure Using Small- And Ultra Small- Angle Neutron Scattering, Chad Alan Novack
Experimental Limestone Dissolution And Changes In Multiscale Structure Using Small- And Ultra Small- Angle Neutron Scattering, Chad Alan Novack
Masters Theses
Small angle neutron scattering (SANS), ultra-small angle neutron scattering (USANS), and backscatter electron (BSE) imaging, along with neutron computed tomography (NCT) were used in this study to experimentally quantify pore size, distribution, and connectivity of dissolved limestone geometries. Eight samples of Indiana limestone of two different initial permeabilities (2-4 mD and 70 mD ) [millidarcy] were reacted with HCl [hydrochloric acid] solutions at differing pH (2 and 4), and flow rates (0.1 and 10 cm3/min) [cubic centimeters per minute] to describe a broad range of parameters that affect limestone dissolution. NCT was first used to image the dissolution …

Resource management technical reports
This report identifies areas of Cockatoo Sands adjacent to the Ord River Irrigation Area (ORIA), Kununurra, with high potential for developing irrigated agriculture. It builds on a reconnaissance soil survey conducted in 2009 which identified significant areas of sandy and loamy soils in the Kununurra area that could be suitable for agriculture.
Impact Of Antecedent Groundwater Heads And Transient Aquifer Storage On Flood Peak Attenuation In An Unconfined Karst Aquifer: Study Of The Upper Suwannee River, Florida, Usa., Jeremy Loucks
Dissertations, Master's Theses and Master's Reports
Flood peak attenuation is an important aspect of understanding flooding and its effects. Few studies exist that look at the effects of ground-surface water interactions in regards to peak attenuation, and fewer still focus on karst environments. In the karstic, variably confined Suwannee River Basin, discharge, river stage, and water table data that were collected over a ten-year period were analyzed to determine the relationship between antecedent groundwater head and flood peak attenuation. Flooding causes high hydraulic heads in the river, which rise faster than corresponding groundwater heads. Springs which normally feed groundwater into the river reverse flow, and conduits …
