ELR was one of the lead developers in the Columbia River Habitat Monitoring Program (CHaMP 2011) where we used the latest in surveying technology to create a protocol to describe stream topography (Bangen et al. 2014) and other important characteristics. This 3D topographic data set can be used to describe very detailed geomorphic, hydraulic and fish habitat characteristics.  Geomorphic units (Wheaton et al. 2015) and geomorphic changes (Wheaton et al. 2009, Bangen et al. 2016) can be delineated and followed through time (e.g. pre- and post-restoration). With discharge, topography can be used to efficiently run 1, 2, 2.5, and 3 D hydraulic models (Nahorniak et al. 2019), providing the basis for fish habitat models.

Reaches

These tools use publicly available data in GIS to efficiently delineated valley bottoms (Gilbert et al. 2016), riparian condition (Macfarlane et al. 2016, Macfarlane et al. 2018), stream primary production (Saunders et al. 2018), stream temperatures (Mcnyset et al. 2015), and beaver dam capacity (Macfarlane et al. 2016) across entire stream networks.

Networks

In collaboration with others (see Riverscapes Consortium), we have develop a host of GIS and stand-alone tools and models to help with watershed assessments, planning, restoration design, and change detection from reaches to networks.
