RESISTIVITY IMAGING OF PROMINENT SEEPAGE PATHWAYS IN KARST TERRAIN
… zones associated with the presence of seepage pathways that were anthropogenic and/or natural in origin. Techniques including visual inspection (VI), multichannel analysis of surface waves (MASW), borehole control (BC), and aerial imagery (AI) were supplementally used to constrain the …

Delineation of a coal combustion residue landfill and underlying karst subsurface in Southwest Missouri using ERT and MASW surveys
… intent to identify potential karst features and seepage pathways.</p> <p>Electrical resistivity tomography data were acquired using an automated 8-channel resistivity meter and multichannel analysis of surface waves data were acquired using a 24-channel Seistronix engineering seismograph and 4.5 …

Geophysical assessment of the Lake Chesterfield site, Missouri
… north beneath the dam through three identified seepage pathways. These pathways should be further investigated. If they are effectively grouted, leakage of lake waters could be effectively minimized.</p><p>In the author's opinion, the most effective mitigation strategy would be to grout the …

Use of Georphysics to Map Subsurface Features at Levee Seepage Locaitons
The Great Flood of 2011 caused moderate to severe seepage and piping along the Mississippi River levees in Northwest Mississippi. The aim of this thesis was to implement geophysical techniques at two seepage locations in order to give a better understanding of the causes of underseepage and …

Stability of tunnels in water saturated shale under cyclic stresses: investigation on the coupling between mechanical and seepage characteristics
… cyclic stress disturbances and its mechanical-seepage coupling properties. The effects of water saturation, hydraulic pressure, and cyclic stress on the mechanical properties and permeability of the specimens were analyzed, leading to an understanding of the degradation mechanism of mechanical …
