25-Jan-2014: poster award to Audrey Eljuri
Audrey Eljuri was awarded 1st place for the best undergraduate poster presentation at the 3rd Annual Jackson School of Geosciences Research Symposium, held today on the UT-Austin campus. Her poster, based on her Honors Thesis work-in-progress, was entitled “The efficiency of storm water management structures, rain gardens and vegetated retention ponds, in reducing urban runoff and contaminants in downtown Austin, Texas”. Congratulations Audrey!
13-Jan-2014: Classes start!
Today begins Kevan’s third teaching semester at UT and second round teaching “Introduction to Physical and Chemical Hydrogeology,” an advanced undergraduate course for geology and environmental science majors, also open to other interested students. She is greatly looking forward to improving upon what was already a highly successful class last year!
16-Dec-2013: AGU success!
The entire research group (and then some) traveled to the annual American Geophysical Union fall meeting last week, the largest international earth science conference. The 7 presentations (talks and posters) in which the group participated were proudly represented among more than 22,000 attendees of sessions on topics ranging from Mars exploration to climate change to water resources to the deep Earth. Welcome back, travelers!
5-Dec-2013: proposal submitted
Kevan submitted a proposal today to the NSF Hydrologic Sciences program with collaborators Ben Hodges, Jim McClelland, and Amber Hardison. Phew! Now we wait…
Today was the last day of Kevan’s fall class: Ecohydrology (GEO 371/391). It was a great semester thanks to a great class and a great TA (Kim Myers)! The course culminated in a class report on the Evapotranspiration of the City of Austin, including daily average and monthly estimates of the vast quantities of water that cycle through the city via evapotranspiration in four major categories of land cover: grassy lawns, undeveloped lands, riparian zones and street trees, and other (impervious surfaces, open water, and urban farms).
22-Nov-2013: welcome Abigail Black
BS Geology Abigail Black will join the research group this spring for a semester of independent study research – topic TBD. Welcome Abigail!
Mike O’Connor joined fellow JSG students to demonstrate the principles of groundwater flow to local school children using an “ant-farm” physical aquifer model, among other props.
1-Nov-2013: welcome Jettie Koen
BS Environmental Science student Jettie Koen will join the research group this spring to complete a senior research project. Jettie will build on the Ecohydrology (GEO 371/391) class project that is estimating evapotranspiration for different land covers in the City of Austin. For her project, Jettie will further improve upon those estimates and conduct a GIS-based analysis of changes in the trends of evapotranspiration over time as Austin has rapidly developed from 1980-2010, using land use maps available from the City. Welcome Jettie!
1-Nov-2013: welcome Ryan Soutter
BS Environmental Science student Ryan Soutter will join the research group this spring to complete a senior research project in collaboration with colleague Todd Caldwell (UT-Austin BEG). Ryan will work in Todd’s laboratory to test the hydraulic and thermal properties of different materials proposed as green roof substrates, part of a larger project Todd is working on regarding the design of grassy green roofs for the City of Austin. Welcome Ryan!
28-Oct-2013: grant awarded to Kevan Moffett
Kevan‘s proposal to the American Chemical Society – Petroleum Research Fund – Doctoral New Investigator program was awarded. The grant will support the research of Kevan and a graduate student for two years on the spatial and temporal patterns of organic carbon generation and preservation in fluvio-deltaic systems as they change morphology over time, specifically targeting the 40-year subaerial history of the Wax Lake Delta of coastal Louisiana.
15-Oct-2013: grant awarded to Audrey Eljuri
Audrey Eljuri‘s proposal to the UT Undergraduate Research Fellowship program was awarded $1000 (the maximum) to help support her Honors research on Austin stormwater management by rain gardens and retention ponds. Audrey will also receive a matching award from the Jackson School of Geosciences, for a total of $2000. Congratulations Audrey!
26-Sep-2013: weather station a-hoy!
Kevan’s Ecohydrology class installed a weather station on the Jackson Geology Building roof today. Every 5 minutes the weather station will record: rainfall, solar radiation (2 sensors: 400-700 nm and 300-1100 nm wavelengths), air temperature, relative humidity, barometric pressure, wind speed, wind direction, and leaf wetness (of a silicon chip that simulates a green leaf). After taking into account that the bare roof is a non-ideal reference surface (although far more secure) compared to a ground-level grassy lawn and comparing with other local data, Audrey Eljuri will use this weather data in her assessment of meteorological influences on Austin rain gardens and retention ponds. The Ecohydrology class will use the data in their final class project regarding the Ecohydrology of the City of Austin. The station will be maintained for some time hereafter, with data available upon request.
17-Sep-2013: welcome Kathleen Stanford
BS Civil Engineering and Bridging Disciplines Program student Kathleen Stanford will be joining the research group this spring. Kathleen will continue our study of stormwater infiltration in Austin rain gardens and retention ponds at the seasonal scale, after Audrey finishes analysis of event-scale responses and graduates this spring. Welcome Kathleen!
16-Sep-2013: student proposal submitted
Audrey Eljuri submitted a proposal today to the UT Undergraduate Research Fellowship program for funds to help support her Honors research on Austin stormwater management by rain gardens and retention ponds.

Congratulations Allan!
26-Apr-2013: media consultation
Kevan Moffett was consulted by a journalist for National Geographic about the science behind an annual festival in Korea. The “Jindo Sea-Parting Festival” celebrates the magical exposure of a hidden path between Jindo and Modo islands. As best as Kevan could determine at short notice, the phenomenon arises from two factors: 1) the particular tidal harmonics occurring at the location and the coastal geometry of the funnel-shaped Myongrang Strait create exceptionally low tides twice a year; 2) the particular tides and currents of the area are likely configured such that they produce a relatively stable quiescent hydrodynamic front between the islands and so allow deposition and long-term persistence of a (usually) subtidal bar of sediments (like a tombolo, but subtidal and likely due to larger currents rather than wave refraction). The regular exposure of this bar by extreme low tides only a few times a year has given rise to both a festival and a legend.

22-Apr-2013: project completion
The 2013 International Space Apps Challenge has come and gone. Suzanne Pierce and Kevan Moffett submitted a challenge to map the surface water resources (mainly playa lakes, a.k.a. salars) in the Chilean Andes through time from remote sensing data and to link those maps to historical preciptiation records for the region. Some participants from around the world submitted projects that at least partly answered this Challenge. Read more at: http://www.jsg.utexas.edu/moffett/2013spaceappschallenge/
