As a multi-disciplinary consulting firm with fish biologists, water resource engineers, hydrologists and geotechnical engineers, GeoEngineers has the right mix of experience and expertise to design sustainable, fish-friendly stream crossings. We begin by looking at existing conditions on either side of a stream crossing and identifying infrastructure factors that may hinder fish passage. Our team then works to integrate culverts, bridges and other crossings into a natural stream morphology that maintains consistent water velocity. Water resource engineers analyze and characterize each stream’s hydrology and hydraulics and make recommendations for grading and channel design that will provide adequate conveyance. By adding habitat features like riparian vegetation, expanded wetlands and large woody debris, our biologists and water resource engineers design sustainable river reaches that will naturally evolve and support fish reproduction over the long-term.
