Levees and Dams : Advances in Geophysical Monitoring and Characterization

This book aims to inform policy-makers, engineers and earth scientists about the current and emerging role of geophysics in addressing environmental processes, assessments, and policy directions related to new and existing dams and levees. Until now geophysics has concentrated on characterization and remediation of dams and levees, but now the field is changing our understanding on the influence of natural processes (e.g., floods, dissolution) and human activities in the design, and management of these structures. This monograph includes advances in the following fields of Dams and Levees studies: · New insights from small and mid-sized laboratory experiments · Integrated methods electromagnetic, seismic, potential methods · Inverse modeling approaches · Statistical considerations · Monitoring of processes attending aging structures · Hazard monitoring · Risk Analysis Front Matter ....Pages i-ix Statistical Estimation of Soil Parameters in from Cross-Plots of S-Wave Velocity and Resistivity Obtained by Integrated Geophysical Method (Koichi Hayashi, Tomio Inazaki, Kaoru Kitao, Takaho Kita)....Pages 1-21 Application of Seismic Refraction and Electrical Resistivity Cross-Plot Analysis: A Case Study at Francis Levee Site (Leti T. Wodajo, Craig J. Hickey, Thomas C. Brackett)....Pages 23-40 A Borehole Seismic Reflection Survey in Support of Seepage Surveillance at the Abutment of a Large Embankment Dam (Karl E. Butler, D. Bruce McLean, Calin Cosma, Nicoleta Enescu)....Pages 41-67 Self-potential Imaging of Seepage in an Embankment Dam (A. Bouchedda, M. Chouteau, A. Coté, S. Kaveh, P. Rivard)....Pages 69-90 Optical Fiber Sensors for Dam and Levee Monitoring and Damage Detection (Daniele Inaudi)....Pages 91-120 Application of the Helicopter Frequency Domain Electromagnetic Method for Levee Characterization (Adam Smiarowski, Greg Hodges, Joe Dunbar)....Pages 121-139 This book aims to inform policy-makers, engineers and earth scientists about the current and emerging role of geophysics in addressing environmental processes, assessments, and policy directions related to new and existing dams and levees.
