Tyler is a Restoration Engineer with extensive experience in water resources and hydraulic engineering in the Pacific Northwest. His experience includes aquatic habitat restoration design, hydraulic and hydrologic modeling, sediment modeling, large wood design, floodplain mapping, geomorphic and habitat assessment, and hydrometric surveying. Tyler’s diverse background includes experience at every step of a project from prioritization and planning to site assessment, literature review, data collection and surveying, modeling and design, permitting, and construction. This experience allows for an interdisciplinary, process-based understanding of project delivery. He has experience developing hydrologic and hydraulic models such as HEC-RAS, SRH-2D, River2D, HEC-HMS, HPSF, MGSFlood, HY-8, SWAT, WMS, SWMM, and StormShed.  He is an experienced jet boat and raft operator in lakes, rivers, and deltas, including for the purposes of topobathymetric and hydrometric surveys. Tyler has experience working on a broad range of river engineering projects such as culvert replacements, hydraulic and hydrologic modeling, floodplain mapping, and bank erosion/scour protection.
