Short Courses

SC-1 Surface Waves Are for Everyone  
Date: Saturday, April 9, 2011 Time: 8 am-5 pm
Coordinator:  J. Ivanov, Kansas Geological Survey  
Instructors:  J. Ivanov, Kansas Geological Survey and Geometrics, Inc. 

This short course focuses on the practical applications of the multichannel analysis of surface waves (MASW) method, presenting the most current approaches to both active and passive estimations of 1-D and 2-D shear-wave velocity (Vs) profiles to depths of a few tens of meters using surface waves. Includes: a brief theoretical overview and field procedures, software practice using a sample data set, a brief field work session using the Geometrics Geode seismograph to demonstrate field procedures and acquire actual field data, and processing of the field data. Participants will be introduced to some of the latest developments in MASW analysis, including practical field-parameter estimations, multi-mode inversion and sensitivity analysis. Also, discussions about future developments, such as 2-D inversion, modeling, and optimized wavelet transform will provide significant food for thought. Course Goal: build a sufficient understanding enabling participants to apply the MASW method in their work. Please bring a Windows 2K/XP notebook/laptop computer - screen resolution set to 1024 x 768 or better. Participants will be provided a 14-day license of SurfSeis 2.05 software. Please be prepared to disable active virus protection software during installation.

SC-2 Advanced Surface Wave (MASW) Methods  
Date: Sunday, April 10, 2011 Time: 1 pm-5 pm
Coordinator: J. Ivanov, Kansas Geological Survey
Instructors: J. Ivanov, Kansas Geological Survey and Geometrics, Inc. 

This advanced course will cover various practical topics related to data acquisition and analysis, such as, optimum field spread-size determination, fixed-spread data acquisition (when having extra phones), muting for enhancement of dispersion-curve images, inversion sensitivity and advantages of a-priori density information. Additional topics can cover case studies (studying levees, mapping fault zones) and most recent MASW advancements (HRLRT for dispersion curve imaging, multi-mode inversion). It is expected that participants will use their own laptops with SurfSeis 3 installed and licensed. 

SC-3: Application of Time-Domain Electromagnetics to Ground-Water Studies
Date: Sunday, April 10, 2011 Time: 8 am-5 pm
Instructor: David Fitterman, Aviva GeoTech

Time-domain electromagnetic (TEM) sounding is well suited to many ground-water investigations ranging from determination of aquifer geometry, delineation of clay zones, estimation of water quality, and mapping of saltwater incursion. Data can be acquired rapidly with minimal field-crew size compared to DC resistivity or seismic methods. The resolution of conductive targets is better than almost any other electrical or electromagnetic method. These attributes make TEM sounding an ideal candidate for small- to regional-scale ground-water studies.

This one-day course is aimed at geophysicists, hydrologists, and geologists who want to learn more about the potential and limitations of the method. The approach will be to begin with theoretical and model studies to understand capabilities and limitations of the method. Real-world field examples will be used to illustrate what can happen in practice and how to deal with these situations. Topics covered include basic principles of TEM sounding, calculation of TEM model response, discussion of what the response tells us, depth of exploration, effect of noise, data collection and processing, data interpretation, survey design, and suggestions about field work.

SC-4: Magnetic Resonance for Groundwater Investigations: Physical Principles and Applications
Date: Thursday, April 14, 2011 Time: 8 am - 5 pm
Instructors: J.-F. Girard, BRGM, A. Legchenko, IRD, Jean Bernard, IRIS Instruments

This course gives an overview of the basic principles of the Surface Nuclear Magnetic Resonance method which permits to directly detect the presence of water underground through surface transmitting and receiving loops readings. The parameters which can be estimated in this method are the depth, the thickness of the aquifer layers and their water content; also their permeability after a calibration with the pumping test results of existing holes. The field data acquisition and processing procedures will be addressed, including the recent signal-to-noise improvement obtained using the remote reference technique. Numerical modelling and 1D, 2D, 3D inversion of data leading to the geometry of aquifers and to their hydrodynamics parameters will be presented and discussed. Topics covered include examples of application in various hydro geological backgrounds, in several countries in the world. This course is aimed at geophysicists, hydrologists and geologists who want to learn more on the capabilities and limitations of the method, for being able to integrate it among the other geophysical methods in the design of groundwater surveys.


SC-5: Geophysical Investigations of Dams and Levees, an Engineering Perspective
Date: Thursday, April 14, 2011 Time: 8 am - 5 pm
Coordinators: Mark Dunscomb, PG, Schnabel Engineering and Douglas E. Laymon, PG, Tetra Tech

How well do you understand the environment you work in and the needs of your clients? More to the point, how can we, as geophysicists, provide suitable services to help characterize dams and levees if we only have a marginal understanding of the world our client’s live in? The purpose of this short course is provide information from an engineering perspective, review the policy and market outlook and their implication to geophysics, and conduct a round table discussion on various geophysical technologies people have used to solve problems on dams and levees. Experienced professional dam engineers will discuss design and construction considerations; historical and potential weaknesses; common analyses conducted regarding dams and levees including what input parameters are needed for the analyses, and how the analyses might improve with better information. Geophysicists with experience in dam assessment will contribute to the discussion of capabilities and limitations of geophysical methods. 


W-1: Advances in Near-surface Electromagnetic Induction Geophysics (jointly sponsored by EEGS and SEG)
Date: Thursday, April 14, 2011 Time: 8 am - 5 pm
Coordinators: M. Everett, Texas A&M Univ. and C. Farquharson, Memorial Univ., Newfoundland

There has been a great deal of activity in near-surface applied electromagnetic induction geophysics in the past several years. New and experienced practitioners are achieving great success in applying the method. Moreover, theorists are becoming better able to exploit the rich
information content that is available in electromagnetic induction datasets. The electromagnetic induction method, with its broad opportunities to design new transmitters, receivers and interpretation tools, continues to offer wide avenues to capture the spatial complexity of the subsurface.
The recent explosive growth of near-surface electromagnetic induction geophysics foreshadows many innovative techniques and applications that are certain to be forthcoming. This workshop is designed for participants to bring forward and discuss new advances in theory, instrumentation, data processing and interpretation, and innovative applications of near-surface applied electromagnetic induction geophysics. Topics will include but not be limited to modeling, inversion, heterogeneity, anisotropy, target recognition, logging and airborne EM, in addition to new or emerging techniques such as landmine detection, biogeophysics, interferometry, shallow-water electromagnetics, radiomagnetotellurics, and airborne UXO discrimination.

W-2:  Application of Geophysical Technologies to Agroecosystems
Date: Thursday, April 14, 2011 Time: 8:30 am-4:30 pm
