A simple global database of river widths and depths was derived using the HydroSHEDS river topology data set and simple geomorphic relationships among area, discharge, width, and depth. This database can be useful to provide initial estimates for hydraulic or hydrologic modeling where other suitable measurements are unavailable. The purpose of this database is not to replace more detailed estimates of river width and depth, but it is a first attempt at mapping these river characteristics with near-global coverage.
