For my masters thesis I studied the morphology and sediment transport of two intermittent rivers along the Balcones Escarpment in Central Texas-- in order to determine what the effects of bedrock, faulting, and landscape have on each river. These rivers are located within two areas maintained by the San Marcos Greenbelt Alliance. With these areas being so close together I focused on the geology and topography of the area as the climate and land cover remain consistent. As with most intermittent rivers, the rivers in this region have been incorrectly mapped or not mapped at all. Also, monitoring the hydrologic regime of the region is virtually impossible with only one USGS stream gauge sensor within 20 km. To solve these problems, I: 1. Mapped/measured the streams morphology before and after the study, 2. deployed passive integrated transponders (PITs) within individual grains clasts to measure sediment transport, 3. Deployed stream, Temperature, Intermittency, and Conductivity sensors (STiCs) throughout the rivers to measure their temperature and intermittency. This research was conducted over the course of nine months; May 2017 - January 2018.
Hydrology is a field that is vital for scientists to continually study due to its interdisciplinary research applications, the plethora of unanswered questions, and because water is required for all lifeforms. Specifically, intermittent river research can not only be applied to study the physical and biological processes here on Earth; the findings and methodologies can be used to study other planetary bodies and examine what direction our planet and water resources are headed. The intermittent river research conducted in central Texas can specifically be applied to aid central Texas’ flood management by characterizing streamflow throughout urban areas as well as further helping us understand the diverse ecological processes occurring in and around intermittent rivers.
I completed this project with the supervision of my advisor, Dr. Katie Costigan, whose website can be found here.

Along with my thesis, I am collaborating with my advisor and Dr. Josh Perkin at Texas A&M (take a look at his excellent research here; he's a fish guy so take it easy on him). This project is tasked with determining the streamflow variability within several rivers in northern Tennessee. The landscape consists primarily of limestones, shales, and chert which produces some incredible waterfalls, however, produces confusion on us trying to figure out what specifically causes the variability in intermittent streamflow.
