Labels are as in Figs 1 and 3. Mean discharge is from July 2015-July 2017.

⁺ For M-A sites, discharge is reported from each river’s nearest USGS gauging station, which are non-tidal and significantly upstream (Aransas ID: 08189700; Mission ID: 08189500).

⁺⁺ As reported by the nearest NOAA tidal gauge station summary [60]. Section H in the S1 File reports the NOAA gauges were used to determine these values.

* Phase offsets are likely of strongly standing character, even though slightly beyond ± 5 degree margin.

** Insufficient TCM velocity data to accurately determine ϕ.
