Abstract

We have developed the global basins database (GBDB). GBDB includes the drainage basins map which consists of polygons of catchments which are subdivisions of basins into elementary drainage areas. Each polygon of a basin is identified by a Pfafstetter code and is attributed with geographic, topographic, and social information. The drainage basins map were generated from digital elevation models of which natural depressions are manually identified and which are modified by the methods of “stream burning” and “ridge fencing”. We used the stream data and the basin data modified by collected data, atlases, and basin maps in the procedures of “stream burning” and “ridge fencing”. The results of comparisons with collected basin maps and upstream areas of the river discharge stations reveals that GBDB provides a more accurate and reliable drainage basins map than HYDROlk database.
