SWOT Prior River Database Reaches

The Reach version of the SWOT Prior River Database SWORD dataset provides high-resolution river reaches (~10 km-long) with attached hydrologic variables (water surface elevation, width, slope, etc.) as well as a consistent topological system for global rivers 30 m wide and greater.

The dataset combines multiple global river- and satellite-related datasets to define the reaches used in the SWOT Level-2 HR River Single Pass - Reach dataset.

The SWOT Prior River Database SWORD product is organized into 9 so-called continents subdivided in subregions.

Please see the Product Description Document and Altenau et al. (2021) for additional information. You may also find SWOT-related tutorials here. The latest release of SWORD may be explored and downloaded on the dedicated website https://www.swordexplorer.com/.
