A reach is a section of a stream or river along which similar hydrologic routing conditions exist, such as discharge, depth, area, and slope.
In GeoHECHMS, reaches can be defined by either drawing or assigning polyline(s) on the Map View using the following commands:
The Draw/Assign Reaches command allows the user to manually draw/assign polylines on the Map View as reaches one after another until completed.
Follow the steps below to use the Draw/Assign Reaches command:
Note that pressing the [Ctrl+E] keys will run the Draw Reaches command directly on the Map View.
The following sections describe how to use the Draw/Assign Reaches command and interact with the above dialog box(s).
The Draw Reach Polylines section is used to draw the reaches on the Map View using polylines. To draw reach polylines, follow the steps below:
The Select Reach Polylines section can be used to manually assign multiple polylines on the Map View as reaches. To assign reach polylines, follow the steps below:
This section is common to both the Draw Reaches and Assign Reaches dialog box and is used to specify the reach ID for each drawn/assigned reach. The user can assign these IDs either manually or automatically using some predefined formats.
Follow the steps below to assign reach IDs to the reaches:
This section is common to both the Draw Reaches and Assign Reaches dialog box and allows the user to assign an invert elevation to the reach using a terrain model. Define this section before drawing/assigning the reaches so that the invert elevations can be assigned.
To assign an invert elevation, the Terrain elevation source dropdown combo box supports the following surface types:
The user can also apply an elevation offset to raise or lower the reach by the specified amount by checking the Apply elevation offset checkbox. On selecting this checkbox, the entry field next to it becomes available for entering an elevation offset value. A negative offset value will lower the reach by the specified amount.
In the Assign Reaches dialog box, an additional Create junctions (if missing) at confluences checkbox option is provided. If the user assigns the reach polylines where the junction(s) are not available, then checking this checkbox option will automatically insert the junction(s) at the confluences.
