West Sacramento, California

 

Jacob is a Restoration Engineer in Training with experience in civil and environmental engineering. He has worked on a variety of projects and programs in Northern California’s Klamath Basin and the California Central Valley. His work emphasizes using remote-sensing methods (LiDAR, sonar, UAS imagery, underwater imagery) to assess physical responses to dam removal. He contributed to the development of methods and analysis focused on tracking a large pulse of fine sediment through the downstream coarse-grained river corridor. In addition, Jacob has served in a civil engineering capacity on flood control structures in the California Central Valley, performing construction inspections, risk assessment, database management, surveying, and permitting. His education and experience have equipped him with skills in H&H modeling, GIS software, and surveying equipment. Jacob’s background in environmental resources engineering provides him with a broad toolbelt of engineering and surveying skills to aid in river restoration and design of fish habitat.
