The Global River Classification GloRiC provides a database of river types and sub-classifications for all river reaches globally.
Version 1.0 of GloRiC provides a hydrologic, physio-climatic, and geomorphic sub-classification, as well as a combined type for every river reach, resulting in a total of 127 river reach types. It also offers a k-means statistical clustering of the reaches into 30 groups. The dataset comprises 8.5 million river reaches with a total length of 35.9 million km.

The data can be downloaded in 2 different formats (click on the zip-file link for download):
- River reaches (line file) in an ESRI Geodatabase (594 MB zip-file).
- River reaches (line file) in a Shapefile (548 MB zip-file).
