![]() On-site shop capability includes custom model bathymetry 5-axis CNC machining for plastics, wood, and metal 3D printing acrylic molding and skilled trades like carpentry, welding, and plumbing. The instrumentation includes capacitance wave gauges, acoustic Doppler velocimeters (ADVs), particle image velocimetry systems (PIV), underwater and surface motion tracking systems, terrestrial LiDAR, and mass property instruments. Each wave flume is equipped with modern piston-type wave generators capable of generating regular waves, random waves, and solitary waves.Īn extensive variety of instrumentation complements the state-of-the-art capability of the flumes. One flume is 1.5 m wide while the neighboring flume is 3 m (10 ft) wide. The larger flumes are both 63 m (208 ft) long and 1.5 m (5 ft) deep, with the testing section viewable through glass. The smaller flume is 0.91 m (3 ft) wide, 0.91 m deep, and 45.7 m (150 ft) long, with glass walls along its entire length. The variation in flume size allows for exploration across a wide range of geometric scales. These flumes support the needs of government organizations and non-government organizations, including academia and the private sector. ![]() Projects range from fundamental research such as water wave physics, wave interaction with natural and nature-based features, and sediment transport to applications such as designing and testing military assets and coastal infrastructure to include armor stability, wave runup, reflection, transmission, forces, and overtopping. The Engineer Research and Development Center (ERDC) Coastal and Hydraulics Laboratory (CHL) houses three state-of-the-art wave flumes that address research, design and development, and site-specific needs in coastal engineering.
