%X This paper presents the current development stage of TerraHidro, a Distributed Hydrology Modeling System created to design Geographic Information Systems (GIS) applications for water flow in hydrographical basins. TerraHidro proposes a different computational representation to deal with water flow in GIS applications. At first, this paper presents the conceptual model of TerraHidro, where the structure used to develop applications is independent from the structures used to extract local flow paths. Since the local flows are primary information for network drainage extractions, the Priority First Search (PFS) method used by TerraHidro to extract these local flows is presented here. PFS method also gives realistic results in flat areas and eliminates all spurious pits in the DEM data with small modifications in the elevation values. Examples of drainage networks are presented and a comparison between TerraHidro and ArcGIS Hydro Tools are presented.
