![]() ![]() ![]() Snaps pour points to the cell of highest flow accumulation within a specified distance.Īssigns unique values to sections of a raster linear network between intersections.Īssigns a numeric order to segments of a raster representing branches of a linear network.Ĭonverts a raster representing a linear network to features representing the linear network.ĭetermines the contributing area above a set of cells in a raster. A weight factor can optionally be applied.Ĭreates a raster of flow direction from each cell to its steepest downslope neighbor.Ĭalculates the upstream or downstream distance, or weighted distance, along the flow path for each cell.Ĭreates a raster identifying all sinks or areas of internal drainage. These fields require an understanding of how water flows. Information about the shape of the earths surface is useful for many fields, such as regional planning, agriculture, and forestry. Arc Hydro Tools version 1.2 Final for ArcGIS 9.2. The Hydrology tools are used to model the flow of water across a surface. ToolĬreates a raster delineating all drainage basins.įills sinks in a surface raster to remove small imperfections in the data.Ĭreates a raster of accumulated flow into each cell. Downloads - Tools These tools have been developed together with the data models to provide new ways to leverage. The Hydrology tools can be applied individually or used in sequence to create a stream network or delineate watersheds. ![]() Hydrological analysis sample applications.Exploring digital elevation models (DEM).The following topics explain how to use the hydrologic analysis functions to help model the movement of water across a surface, the concepts and key terms regarding drainage systems and surface processes, how the tools can be used to extract hydrologic information from a digital elevation model (DEM), and sample hydrologic analysis applications. When modeling the flow of water, you may want to know where the water came from and where it is going. Fills sinks in a surface raster to remove small imperfections in the data. Creates a raster delineating all drainage basins. These fields require an understanding of how water flows across an area and how changes in that area may affect that flow. The Hydrology tools can be applied individually or used in sequence to create a stream network or delineate watersheds. Information about the shape of the earth's surface is useful for many fields, such as regional planning, agriculture, and forestry.
