CHANNEL MORPHOLOGY, STREAMFLOW PATTERNS, AND SEDIMENT TRANSPORT OF TWO INTERMITTENT RIVERS ALONG THE BALCONES ESCARPMENT
The rise of intermittent river research coincides with them becoming increasingly more prevalent on Earth due to climate change and water abstraction, among other factors. To date little research is focused in areas with greater rainfall amounts, such as in central Texas. Here, we collected data over the course of nine months within two public parks in Central Texas to determine how their morphology changed over time, their capacity to transport sediment, and the drivers of their intermittency. To answer these questions, three methods were used: 1. Morphology changes with ten cross-sectional profiles measured at the beginning and end of the study; 2. Passive Integrated Transponders were inserted into 60 grains varying in size to track how far those grains traveled after a rainfall event; and 3. 30 Stream, Temperature, Intermittency, and Conductivity sensors deployed longitudinally down each river to determine where and when water is present. In each intermittent river, little to no sediment transport was recorded, despite the historical rainfall associated with Hurricane Harvey.
