Stream Alignment

A common schematic is used to share effectively common data between HEC software (for example, HEC-HMS and HEC-ResSim) for a watershed. Use of this common schematic ensures consistency of computation nodes, routing reaches, and so on.

In the Setup module, you use tools to create the common schematic. Setup module provides an overview of the setup module and the tools available in the module. The tools allow you to depict elements of the common schematic—but not change the configuration of the native models. Changes made with the tools are not accounted for in the native models' computations.

The first item to create in the common schematic is the stream alignment. A stream alignment is the backbone for all the other elements that make up a common schematic. This section will describe the tools and concepts for creating a stream alignment.
