River gravel mobility observations, San Antonio River, Texas

<p>This data set characterizes the frequency of gravel mobility in the lower San Antonio River near Floresville, Kenedy, and Goliad, Texas.&nbsp; Mobility data consist of the first flow discharge when a given gravel size was mobile, the general bedload transport conditions during these mobilizing flows, the frequency of mobilizing flow during in a typical year based on flow duration analysis, and the grain size distribution of bed material.&nbsp; &nbsp;Details are given in Haschenburger (2022), Frequency of river gravel mobility, Geomorphology, 410, 108270, https://doi.org/10.1016/j.geomorph.2022.108270</p>
