Hydrology, Soils, & Topography Data
River discharge, which is the integrated signal of runoff, is perhaps the most accurately measured component of the hydrological cycle (Hagemann and Dümenil, 1998; Krahe et al. 1996; Rantz, 1982) but it is not yet fully utilized in Earth system studies partly due to the limited access to such data and the difficulties relating the point measurement of discharge to the other components of the hydrological cycle. This situation is changing by the increasing number of nations publishing discharge related information via the World Wide Web, and the World Meteorological Organization's recent effort to establish the hydrological component of their Global Terrestrial Network (Cihlar 2001). Recently released gridded networks with global extent (Vörösmarty et al. 2000a, 2000b, Oki and Sud, 1998, Graham et al., 1998) provided the means to establish the linkage between the landmass and the river channels (and ultimately the oceans).

 Data Set Documentation |
This data set consists of river discharge point data from the Global Runoff Data Centre (GRDC) for all 390 stations with measurements in the period 1986-1995. The two river discharge files are called grdc_river_disch1986-1995.dat and grdc_stations1986-1995.dat and contain the monthly river discharge for appropriate GRDC gauging stations and ancillary information on the stations (e.g. location, river basin name, etc...), respectively. These data are text files where each column of data is separated by a "tab" character (i.e. tab-delimited file). These files can be easily imported into standard spreadsheet programs.
