Description:

The GRWL Database was built to characterize the global coverage of rivers and streams. The GRWL Database is the first global compilation of river planform geometry at a constant-frequency discharge. A global database of 3,693 gages were used to determine the months when the rivers were commly near mean discharge; 7,376 Landsat THM, ETM+, and OLI scenes were capture during those months. Image processing techniques were used to classify rivers, measure their location, width, and braiding index. The dataset was validated using in situ river width measurements collected by USGS and the Water Survey of Canada.
