Observed and naturalized discharge data for large Siberian rivers



The data set includes two types of discharge data: 1) observed daily discharge values compiled in the State Hydrological Institute, Russia from official sources and 2) modeled "naturalized" daily discharge. The "naturalized" discharge means discharge values with excluded human impact. The data can be used in hydro-climatological analysis to understand interactions between climate and hydrology. A specially developed Hydrograph Transformation Model (HTM) was used to eliminate effects of reservoirs and other human impact from discharge records.

These data are formatted as text documents.
