“Comparing Surface Interpolation Techniques for Accurate
Target Location using an Electromagnetic Survey over Buried
Steel Drums”
Presented by Bowen Liu, University of Pennsylvania
Electromagnetic surveys are commonly used in geophysics to
locate buried metallic objects such as 55-gallon cold-rolled
carbon steel drums. The field data is plotted on a map and
interpreted for target locations. This research project uses
electromagnetic field data collected at discrete points over
buried drums to generate continuous surfaces using several
interpolation techniques. The field survey used a Geonics
EM31 Terrain Conductivity device to measure the apparent
conductivity per meter, as well as, the inphase ratio of
secondary to primary magnetic fields at an experimental
station in Spinnerstown, Pennsylvania. The targets were buried
drums oriented north south and east west. The data was
synchronized to a global positioning system which provided
georeferenced geophysical measurements. Multiple data sets
were collected over a single drum and by using several drums
these data sets provided statistical replication. The surfaces
were created in a geographic information system using
common interpolation techniques and the results were
compared to determine which interpolation technique is the
most accurate for finding drums using an electromagnetic
survey.

“Using GIS to Model the Watersheds in Chester County”
Presented by Britney Vazquez, University of Pennsylvania
Land cover changes are an important factor to consider in any
watershed basin analysis. An increase in impervious areas due
to urban development leads to increases in runoff, which in
turn affect the health of watersheds. Geographic Information
Systems, or GIS, was used to analyze the impacts of land cover
changes in the watersheds of Chester County, PA on runoff
generation using three different land cover layers: 1992, 2001,
and 2011. The watersheds for each USGS gauge were also
constructed using Arc Hydro Tools. The Soil Conservation
Services Runoff Curve Number (CN) method was used to
determine the amount of runoff in the county as a whole, as
well as in each individual watershed. Water quality data was
also collected in order to analyze any relationships between
land cover changes and the health of the watersheds. Land
cover was found to be significantly different between each
year, with the total developed area increasing from 19% to 40%
from 1992 to 2011. The total vegetation area decreased from
44% to 34% during this time period. In addition, several USGS
gauges within the county displayed significant increases in
discharge, pH, and specific conductivity and decreases in
turbidity from 1992 to 2011.

“Comparison of Field and Laboratory Methods for Measuring
Hydraulic Conductivity in the Unsaturated Zone in Engineered
and Native Soils”
Presented by Pablo R. Garza, Villanova University
Stormwater control measures (SCMs) are used in urban and
suburban areas to control runoff volume and peak flow rates, as well
as improve the quality of runoff water. Rain gardens are one type of
vegetated SCM which can contain engineered or native media. A
major component used in design and performance of SCMs and rain
gardens is hydraulic conductivity, which can be measured in the field
using various infiltration testing techniques. Infiltration testing can be
performed during initial site investigations to determine the
appropriate SCM design and performed post-construction to ensure
the SCM is performing well. The double-ring infiltrometer (ASTM
D3385) is the most commonly used technique. However, the double-
ring can be cumbersome because the infiltrometers are large and
require a great deal of energy to install and a large quantity of water
to perform. In this study, the authors employed various infiltration
techniques to determine the in-situ hydraulic conductivity at various
sites. These sites included rain gardens of varying ages with
engineered media, as well as a site with native soils where test pits
were dug during an investigation to determine future SCM design.
The authors built a Modified Philip-Dunne Infiltrometer and
compared it to other field methods such as the double-ring and
single-ring infiltrometer. Additionally, a falling-head PVC pipe test
was designed by the authors and is also used in the comparison
study. The in-situ measurements obtained with the Modified Philip-
Dunne test were compared to laboratory values obtained with the
UMS KSAT Benchtop Saturated Hydraulic Conductivity Instrument,
which complies with DIN 19683-9 and DIN 18130-1. Preliminary
results indicate that the Modified Philip-Dunne provides results
similar to the other tests methods, producing hydraulic conductivities
within one order of magnitude as the other methods.
