The Schematic Processor is a set of ArcGIS (version 10) geoprocessing script tools for processing Arc Hydro schematic networks. The tools give you the ability to associate behavior with schematic features. For example, if you are simulating the movement of bacteria through a stream network, the schematic processor can decay the bacteria as they move along schematic links representing stream segments.
The behaviors assigned to schematic features are implemented with snippets of Python code called processing ops. A few ops for handling tasks such as simple accumulation of values downstream and first order decay are included with the download. You can also write your own ops to simulate whatever behavior is desired. Instructions on writing ops and on the tools in general are included in the documentation for the tools.DOWNLOAD
