Assessing the Periodic Groundwater Flow Conditions of a Perched Aquifer System in the Daniel Boone National Forest

Ethan Sweet and Jonathan Malzone

Eastern Kentucky University, Department of Geosciences

Natural ephemeral wetlands situated among the ridge-tops in the Daniel Boone National Forest serve as reservoirs that recharge a shallow groundwater system. Unique interactions between surface and groundwater in these isolated systems provide substantial support for the native ecosystem, serving as a breeding ground for amphibians and as source water for vegetation—especially in periods of drought. Currently it is not understood how groundwater could provide regional biodiversity, a drought buffer, or a …

Murray State University, Hutson School of Agriculture, Kentucky, USA

Abstract

Cropping practices leading to loss of soil organic matter thus can alter other soil properties. The purpose of this study was to determine the impact of crop and non-crop areas on soils. Disturbed and undisturbed soil samples were collected from different fields of corn, soybeans, tobacco, pasture, and wooded areas in the Southwest portion of Calloway County, Kentucky on September 8, 2017. The properties observed …

Improving The Accuracy For The Long-Term Hydrologic Impact Assessment (L-Thia) Model, Anqi Zhang, Lawrence Theller, Bernard A. Engel

The Summer Undergraduate Research Fellowship (SURF) Symposium

Urbanization increases runoff by changing land use types from less impervious to impervious covers. Improving the accuracy of a runoff assessment model, the Long-Term Hydrologic Impact Assessment (L-THIA) Model, can help us to better evaluate the potential uses of Low Impact Development (LID) practices aimed at reducing runoff, as well as to identify appropriate runoff and water quality mitigation methods. Several versions of the model have been built over time, and inconsistencies have been introduced between the models. To improve the accuracy and consistency of the model, the equations and parameters (primarily curve numbers in the case of this model) …

Mobility Characteristics Of Azithromycin In Soil, Ryan Minter, Jihyun Kim, Linda Lee

The Summer Undergraduate Research Fellowship (SURF) Symposium

The presence of pharmaceutical and personal care products (PPCPs) in the environment has become a widespread problem in recent decades. Azithromycin, a macrolide antibiotic commonly prescribed for infections in humans, has been detected in waste treatment plant discharge and surface waters across the world. Data on the mobility characteristics of azithromycin in soil is scarce, and further studies must be performed to explore the potential for azithromycin leaching to groundwater or becoming available for plant uptake. In this study, azithromycin sorption isotherms were measured on eight soils varying in pH, organic carbon content, and clay content. Soil was equilibrated with …

Using P-Band Signals Of Opportunity Radio Waves For Root Zone Soil Moisture Remote Sensing, Phillip H. Lipinski, Benjamin R. Nold, James L. Garrison

The Summer Undergraduate Research Fellowship (SURF) Symposium

Retrieval of Root Zone Soil Moisture (RZSM) is important for understanding the carbon cycle for use in climate change research as well as meteorology, hydrology, and precision agriculture studies. A current method of remote sensing, GNSS-R uses GPS signals to measure soil moisture content and vegetation biomass, but it is limited to 3-5 cm of soil penetration depth. Signals of Opportunity (SoOp) has emerged as an extension of GNSS-R remote sensing using communication signals. P-band communication signals (370 MHz) will be studied as an improved method of remote sensing of RZSM. P-band offers numerous advantages over GNSS-R, including stronger signal …

Recreating Intercalated Clays Of Chondritic Meteorites, Katherine Winchell

Scholars Week

In order to better understand the reactions that form intercalated clays in carbonaceous chondritic (CC) meteorites, a suite of six combinations of nontronite plus fine-grained metal, organics, or sulfur ± water were heated at a temperature of 200°C in sealed Parr bomb containers for a period of three months. Intercalation is the process of materials being introduced between the layers of expandable clays via cation exchange. Reflectance spectra of CC meteorites differ from those of mixtures of the end members made physically in that the CC spectra are darker and show extremely subdued absorption bands of the phyllosilicates (clays) that …

Analysis Of Concentric Growth Rings In Hydrothermal Epidote, Brandi Petryk

Scholars Week

Crystals found within geothermal cores from Akutan Island, Alaska, show concentric growth rings of what appear to be alternating bands of epidote and clinozoisite minerals. The intent of this project is to determine the nature of these growth rings and what processes could allow them to form. Our working hypothesis is that the rings are due to fluctuations in the oxidation states of the hydrothermal system, which would control the amount of available Fe3+ needed to make epidote. In relatively reducing conditions, Fe3+ would be scarce and clinozoisite (Fe-poor variety of epidote) would form. We have tested this hypothesis by …

An Operational Drought Prediction Framework With Application Of Vine Copula Functions, Mahkameh Zarekarizi

Student Research Symposium

Early and accurate drought predictions can benefit water resources and emergency managers by enhancing drought preparedness. Soil moisture memory is shown to contain helpful information for prediction of future values. This study uses the soil moisture memory to predict their future states via multivariate statistical modeling. We present a drought forecasting framework which issues monthly and seasonal drought forecasts. This framework estimates droughts with different lead times and updates the forecasts when more data become available. Forecasts are generated by conditioning future soil moisture values on antecedent drought status. The statistical model is initialized by soil moisture simulations retrieved from …

The Effects Of Urbanization On Nitrogen Processing In Urban Streams, Peter Francissen, Dr. Kevin Geedey, Dr. Michael Reisner

Celebration of Learning

Urban stream syndrome is described as the deterioration of stream health in an urbanized watershed and is associated with the loss of ecosystem services, which in turn degrades downstream environments. One key symptom of the urban stream syndrome is reduced processing of inorganic nitrogen. Previous research suggests that as urbanization increases and water quality decreases, the uptake length (Sw) of inorganic N increases. This indicates that the stream is increasing the export of N downstream compared to in situ incorporation of N into the ecosystem. We measured uptake length (Sw) of NO3, using a pulse addition method, along 9 different …

Summer Precipitation Occurrence Effect On Two Passerine Species In Thule, Greenland, Sara E. Baugh

Celebration of Learning

Climate change is occurring at a faster rate in the Arctic than the rest of the globe, causing temperature rises at twice the rate of the global average and increased summer precipitation in the form of rain. These precipitation events are predicted to affect migratory bird species that breed throughout the Arctic. Increased occurrence of heavy rainstorms indirectly affect bird populations by impacting distribution and abundance of food supply, and directly by increasing mortality rates of juveniles. Studies conducted on bird species throughout the low Arctic regions; have shown that it is not the total precipitation of a breeding season …

A Spatial Relationship Between Stream Slope Stability And Water Quality Within An Urban Watershed In Rock Island, Il, Joseph Teresi

Celebration of Learning

The consistently observed phenomenon of highly altered streams and degraded water quality draining urban areas across the U.S is described as the urban stream syndrome. Rock Island, Illinois, contains a population of nearly 39,000 people, and houses industrial and logistical businesses amidst a city of aging infrastructure. Streams occupy ravines that have incised into the Quaternary loess plateau, flowing south towards the Rock River and north or west towards the Mississippi River. In an attempt to understand better the severity of Rock Island’s urban stream syndrome, this project analyzed stream slopes within the Rock Island watershed to categorize their level …
