ABSTRACT:

This is the location for the U.S. Geological Survey Surface Water and Ocean Topography calibration data intended for the Surface Water and Ocean Topography Hydrology Community Discharge (SWOT SHCQ). The SWORD network version used here is v16. Discharge, depth, water surface elevation, velocity, cross-sectional area, width, measurements were taken with the Sontek M9 and Teledyne RiverPro and processed with Qrev. Data was collected on the Ikopa and Betsiboka rivers in Madagascar, and the Cubango/Okavango River in Botswana, Namibia, and Angola. Discharge measurements at gage locations were collated from the U.S. Geological Survey and Environment and Climate Change Canada. Questions can be directed to mharlan@usgs.gov.

ABSTRACT:

***Update Aug-2026***
We are now updating to using SWORDv17.
We have incorporated a translation step so that previously submitted data will still be processed and used but we ask that any updated submission use SWORDv17 reach IDs.

Note that while translation will keep existing data in use, we highly recommend updating files to SWORDv17 reaches as this will guarantee this best assignment accuracy.

A gathering place for community hydrology data to be used in constraining and validating SWOT river discharge parameter estimates . How can you help? First find the .csv template in this collection and the associated readme file describing it (both 'TEST_Example Data' resources have it). Then construct your own resource with a csv file within. We request users submit CSVs following the template provided (SWOT_SHCQ_template.csv), and that they limit thier contributions to one such file that they update when needed. Leaving the resource unpublished allows users to update that file over time. Check manage access, and make sure your resources is set to public and sharable. Finally, use the SWOT_file_check_utility resource in this collection to verify that your file will be parsed correctly in confluence (instructions in that resources abstract). Then submit a link to Steve Coss via email coss.31@osu.edu. You may find that changes to your unpublished resource do not save after editing and closing the editor. This issue can be bypassed by clicking into the resource name field, entering any key stroke (even space) then deleting any new characters. Next click save changes. The resource contents should now be updated in the cache.
