Abstract

This paper describes TerraHidro that is a distributed hydrologic modeling platform. TerraHidro is general purpose water resources system that presents a new concept to represent water flows based on graph structure, in the geographic information system (GIS) context. The drainage extractions and Amazonian basin delimitations using TerraHidro have been compared with ArcGis Hydro Tools regarding to drainage extractions and to show the TerraHidro availability the drainage of Amazonian sub basins, called Xingu, Purus and Tapajos are presented.
