Right-click on Stream Alignment map layer in the Map Layers tree, and the shortcut menu opens.Click the Maps tab in the HEC-WAT main window.Stream alignments define stream stationing for the study area.
WAT FIX TOOL SERIES
Stream alignments are composed of a series of streams, stream nodes, and stream junctions.
Create a Stream AlignmentĪ stream alignment is a one-dimensional river coordinate system, which defines the natural downstream flow network. Note, the steps for defining schematic elements also include instructions for creating additional alternative measures (e.g., diversions, channel modifications, off-channel storage areas, other project elements). The steps to define the default schematic are outlined in the following sections. Schematic elements and/or measures can be imported from a shapefile (only for the stream alignment, common computation points, reservoirs, levees or impact areas) or added manually in the schematic map window (using the Schematic Map Tools). This default schematic needs the basic schematic elements - stream alignment, common computation points, measures (reservoirs, levees), and impact areas to be defined by the user. A schematic is automatically created with the default alternative using the same name selected by the user. When a new study is created in HEC-WAT, a default (base) alternative is created with either an HEC-WAT default name ( Without Project Conditions) or a user-defined name.
