Texas

Red-Washita River Basin

Left: the Texas part of the Red-Washita basin (WBD HUC4 1113, clipped to Texas) with its NHDPlus HR network, its larger lakes and reservoirs, and our two models (USGS 07312200 and USGS 07315200) in orange. Right: the USGS 07312200 model drawn large, every one of its channels, with its water bodies in blue.

  • 2 published SWAT+ models
  • NHDPlus HR: 36,231 km of network flow paths in its Texas HUC8s, 3.14x NHDPlus V2.1's 11,533 km
  • 12 USGS gauges with a 90 % daily record, 2014-2024, in its Texas HUC8s (6 of 8 HUC8s covered)
  • 8 HUC8s mostly in Texas, 22,369.7 km² in all (WBD HUC12 sum)

Basin: HUC4 1113 (Red-Washita) of the USGS Watershed Boundary Dataset.

Each point is one basin (WBD HUC4), over its HUC8s that lie mostly in Texas: its network flow paths in NHDPlus Version 2.1 (across) and in NHDPlus HR (up), filled with canals and ditches in both counts, hollow without them. On the line, the two would be equal. Ringed: the two datasets' areas for this basin differ by more than 5 %: Galveston Bay-San Jacinto, Brazos Headwaters, Lower Brazos, Upper Colorado, Lower Colorado-San Bernard Coastal, Central Texas Coastal, Rio Grande Closed Basins, Lower Pecos and Rio Grande-Falcon. In this figure, this basin's points are orange.

A model of your Texas watershed

We build a SWAT+ model for a USGS stream gauge in Texas, from national data. You download it as files you open in SWAT+ Editor and run, and you keep the files.

Free, $0, to try it on a real station. Starter, $50 / month USD. MAX, $100 / month USD. Cloud calibration is pay as you go, on every plan including Free.
