Hydrology tools arcgis

Understanding drainage systems Exploring digital elevation models DEM Deriving runoff characteristics Creating a depressionless DEM Creating watersheds Hydrological analysis sample applications The Hydrology tools can be applied individually or used in sequence to create a stream network or delineate watersheds.

Tool Description Basin Creates a raster delineating all drainage basins. Fill Fills sinks in a surface raster to remove small imperfections in the data. Flow Accumulation Creates a raster of accumulated flow into each cell. Flow Distance Computes, for each cell, the horizontal or vertical component of downslope distance, following the flow paths, to cells on a stream into which they flow.

Flow Length Calculates the upstream or downstream distance, or weighted distance, along the flow path for each cell. Sink Creates a raster identifying all sinks or areas of internal drainage. Snap Pour Point Snaps pour points to the cell of highest flow accumulation within a specified distance. Storage Capacity Creates a table and a chart of elevations and corresponding storage capacities for an input surface raster. Stream Link Assigns unique values to sections of a raster linear network between intersections.

Stream Order Assigns a numeric order to segments of a raster representing branches of a linear network. Stream to Feature Converts a raster representing a linear network to features representing the linear network. It deals specifically with the issues listed below under Issues Addressed with this Patch. Check the Patches and Service Packs page periodically for the availability of additional patches.

New information about this patch will be posted here. To determine which ArcGIS products are installed, choose the appropriate version of the PatchFinder utility for your environment and run it from your local machine. PatchFinder will list all products, hot fixes, and patches installed on your local machine. Domestic sites, please contact Esri Technical Support at , if you have any difficulty installing this patch.

International sites, please contact your local Esri software distributor. Technical Support. Esri Support app 4. Computes, for each cell, the horizontal or vertical component of downslope distance, following the flow path s , to cell s on a stream into which they flow. In case of multiple flow paths, minimum, weighted mean, or maximum flow distance can be computed.

Flow Length. Calculates the upstream or downstream distance, or weighted distance, along the flow path for each cell. Creates a raster identifying all sinks or areas of internal drainage. Snap Pour Point. Snaps pour points to the cell of highest flow accumulation within a specified distance. Stream Link. Assigns unique values to sections of a raster linear network between intersections.

Stream Order. Empowering your work. Data management Create raster and vector GIS representations of the landscape and built environments for water resource analyses. Integrated data systems Integrate raster, vector, tabular, and network data into an efficient and consistent modeling foundation that is easy to extend and configure for specific GIS implementations. Analysis Identify sinks; determine flow direction; calculate flow accumulation; and delineate and characterize watersheds, stream networks, and floodplains.
