River gravel mobility observations, San Antonio River, Texas

This data set characterizes the frequency of gravel mobility in the lower San Antonio River near Floresville, Kenedy, and Goliad, Texas.  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.   Details are given in Haschenburger (2022), Frequency of river gravel mobility, Geomorphology, 410, 108270, https://doi.org/10.1016/j.geomorph.2022.108270
