| Short Courses
& Workshop
This year,
SAGEEP offers a full-day Workshop in addition to its Short Course
line up. Be sure to review these offerings of full-day and half-day
presentations. Please note that some Short Courses begin Saturday,
April 10. The following courses include full course notes, continental
breakfast and morning and afternoon refreshments. Students registering
at the Student Rate will be accepted based on space available basis
and provided with electronic media course work materials.
Short
Courses
SC-1: Surface
Waves Are for Everyone (Active and Passive MASW)
Date: Saturday, April 10, 2010
Instructors: Julian Ivanov, Kansas Geological Survey and Geometrics,
Inc.
Time: 8am - 5pm
This one-day 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. The short course will include: a brief theoretical overview
and field procedures to ensure success, 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 you acquire. 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. The goal of the short
course is to build a sufficient understanding that participants
are confident in applying the MASW method in their work. Participants
are encouraged to bring a Windows 2K/XP notebook/ laptop computer,
which can have the screen resolution set to 1024 x 768 or better,
to process short course data. Participants will be provided a 14-day
license of SurfSeis 2.05 software. Please, be prepared to disable
active virus protection software during installation.
Seismic
Refraction Tomography Short Course, Now In Two Modules!
Back by Popular Acclaim! Presented for the first time at SAGEEP
09, the popular Seismic Refraction Tomography Course has been revised
and expanded with separate Principles/Applications and Software
components. Participants may register for either or both.
SC-2A: Processing
of Seismic Refraction Tomography Data
Date: Saturday, April 10, 2010
Instructors: Siegfried Rohdewald, Intelligent Resources Inc., Bethany
Burton, USGS, Jacob Sheehan, Battelle
Time: 1- 5pm
This
module, either as a stand-alone or as an optional component to accompany
SC-2B provides hands-on training with the Rayfract Seismic Refraction
Tomography software package. A limit of 25 participants has been
established due to the interactive nature of software training.
Those enrolling should bring a laptop computer running Windows XP,
Vista, or 2000, and should plan on installing the Rayfract software
in advance of the course (available at the registration desk). They
will be provided with a one-month software license on CD-R with
a USB dongle.
SC-2B: Principles
and Applications of Seismic Refraction Tomography
Date: Sunday, April 11, 2010
Instructors: William Doll, Battelle (Coordinator); Colin Zelt, Rice
University; Julian Ivanov, Kansas Geological Survey; Mike Powers
and Seth Haines, USGS; Jacob Sheehan, Battelle
Time: 8am -5 pm
Tomographic
analysis of seismic refraction data has evolved over the past ten
years from an academic pursuit to routine field application. Several
studies have demonstrated vulnerabilities of this technique, due
to non-uniqueness, ray coverage constraints, and initial model selection.
Course presentations range from very practical and applied guidelines
and applications to current research topics. Underlying conceptual
and theoretical concepts will be addressed to provide a core understanding
that is essential for proper application. Modules include: Modeling
approaches and assessment strategies; Pitfalls; Software Comparison;
Engineering and Other Applications; Shear Wave Refraction Tomography;
Frequency-Dependent Traveltime Analysis; Full Waveform Inversion;
and 3D Analysis
SC-3: Application
of Time-domain Electromagnetics to Ground-Water Studies
Date: Sunday, April 11, 2010
Instructors: David Fitterman, USGS Emeritus
Time: 8am - 5pm
Time-domain electromagnetic (TEM) sounding is well suited to many
ground-water investigations ranging from mapping of saltwater intrusion,
estimation of water quality, delineation of clay zones, and determination
of aquifer geometry. 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 all electrical and electromagnetic
methods. These attributes make it 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, and follow with real-world field examples
to illustrate what can happen in practice and how to deal with these
situations. Topics covered include basic principles of TEM, calculation
of TEM model response and it tells us, depth of exploration, effect
of noise, data collection and processing, data interpretation, survey
design, and suggestions about field work.
SC-4: Geophysical
Investigations of Dams and Levees
Date: Thursday, April 15, 2010
Instructors: Phil Sirles, Zonge (Coordinator), Lewis Hunter (U.S.
Army Corps of Engineers), Richard Markiewicz (Bureau of Reclamation),
Michael Powers and Burke Minsley, (USGS)
Time: 8am - 5pm
This
one-day short course focuses on applications of a variety of geophysical
methods used to investigate the internal features of embankment
dams and levees. Due to inherent public safety concerns related
with these structures, the course will be presented by a series
of experts who either worked at- or work for- agencies that own
and maintain the structures. Each instructor has worked for many-many
years on data acquisition, processing and presentation of geophysical
data collected on dams or along levees for use by geologists and
engineers, but primarily geotechnical engineers. Applications will
range from evaluation of seepage-related issues to assessment of
the structural integrity of dam & levees or their foundation
geology, as well as the evaluation of specific appurtenant structures
(e.g., spillways, outfalls, etc.). Geophysical field methods presented
will include: electrical resistivity, self-potential, seismic (P-
and S-waves), GPR, and LiDAR. Additionally, the value of borehole
geophysics will be addressed. The course will focus on how geophysical
data can be acquired and then presented in a manner that enhances
the engineering evaluation, design, and remediation needs. Survey
approaches will be shown from 1D, 2D, 3D and 4D geophysical techniques.
The goal of the short course will be to create a better understanding
of dams and levees, and how best to utilize geophysical imaging
techniques to characterize the structures or foundations. Since
geophysical data ultimately get used in the safety analysis, the
engineering design, and/or the remediation of public and privately
owned high-risk structures this short course is particularly valuable
for anyone working on dams and levees that does not yet understand
the value and benefit these surveys provide. Participants will be
shown case histories from large and small structures, in order that
they may best apply geophysics (or inquire about using geophysics)
on projects of their own.
Workshop
W-1: Airborne
EM for Environmental and Engineering Applications
Date: Thursday, April 15, 2010
Coordinators: Jeff Paine (Univ. Texas) and Paul Bedrosian (USGS)
Time: 8am - 5pm
The use
of airborne electromagnetic (AEM) methods for environmental, hydrogeological
and engineering purposes continues to expand as more organizations
recognize the benefits of rapid and extensive coverage offered by
airborne instruments. This expansion has been augmented by advances
in instrumentation, data acquisition and processing, and inversion.
This technical, interactive workshop will highlight the capabilities
of modern helicopter-borne and fixed-wing AEM systems (especially
the newer time-domain systems) together with case studies on the
use of AEM data for environmental, engineering, and hydrogeological
investigations. Representatives from several AEM companies will
be speaking as well as leaders in the field of AEM data processing
and application.
