Johnson Creek - West Lents Geospatial Services

By applying integrated geomorphic/ remote sensing/ restoration effectiveness assessment experience W2r assisted Portland BES in their project monitoring program and identified considerations for their future stream restoration efforts. We used multi-spectral imagery (Normalized Difference Vegetation Index) along with terrain modeling to evaluate several implemented restoration projects. We assessed vegetation health through near-infrared and red-edge bands, as well as geomorphic position relative to the base flow, and gained insights into where riparian zones have trouble establishing, as well as design and construction methods that yield the best outcomes for vegetation establishment. Implications to future design work include designing a shallow baseflow channel and extensive floodplain lowering to maximize riparian vegetation access to near surface groundwater.

COMMITMENT TO EQUITY

While work in the water and natural resources fields has been built around protecting and preserving nature, it has not always protected or accepted all people. Wolf Water Resources recognizes the exclusive history of engineering and environmentalism and we are diligently working towards more diverse collaborations. Diversifying our profession is a vital and on-going journey, and W2r commits to interviewing 100% of minority applicants and providing contacts and recommendations when we do not have an immediate employment opening. W2r also actively involves minority, woman, and veteran-owned firms on project work and in business operations.
