Water Resources Analysis & Engineering
R2 has strong engineering expertise in hydraulic, sediment transport, and operations modeling, especially as it relates to spawning gravel quality and stability, channel restoration, and fish passage (upstream and downstream). R2's technical experts have performed a variety of hydrologic and hydraulic studies, including the design of both open channel and closed conduit flow structures. In addition, R2 has specific expertise in river engineering and sedimentation related to aquatic habitat quantification, protection, and restoration. This expertise includes extensive analyses of channel form, stability, sediment composition and transport, large woody debris impacts, and other aspects of fluvial geomorphology.
