Riverscape Valley Bottoms

Riverscapes Valley Bottoms are a key component of developing a LTPBR restoration project. They provide the spatial context for the restoration project and represent the theoretical physical space for restoration to occur.

You can have as many Valley Bottoms within your project as you like.

Add an Existing Valley Bottom

You can import an existing valley bottom polygon feature class or temporary map layer into QRiS. To do this, click the Import Existing Valley Bottom From... menu item on the Riverscapes Node within your QRiS project. Select the temporary map layer, or browse to the location of the polygon feature class and click Open. Provide a name and optional description for the Valley Bottom. You can also define key/value pairs of metadata that help describe the origin of the data. Click OK to import and create a copy of the feature class will be added to your project..

A common workflow is to import a VBET valley bottom into QRiS.

Create a New Valley Bottom

You can create a new valley bottom by manually drawing a polygon on the map. To do this, click the Create New (Manually Digitized) Valley Bottom menu item on the Riverscapes node within your QRiS project. Provide a name and optional description and then click OK. Add the Valley Bottom layer to the map by clicking the Add to Map button. You can now use the standard QGIS editing tools to digitize the valley bottom on the map. Remember to stop editing and save your changes to the valley bottom feature.
