Due to the numerous demands placed on our Nation’s rivers, waterways, and estuaries, CHL’s river and estuarine engineering expertise remains as important today as it was over nine decades ago when it formed the foundation of the first federal hydraulics research facility. CHL continues to leverage its proximity, knowledge, and experience of the Mississippi River and coastal Louisiana to solve the most complex river and estuarine problems across the Nation. These core competencies include the development and application of advanced instrumentation and sensing equipment, field data collection techniques, numerical models, and physical modeling to solve problems related to river and estuarine hydraulics, sediment transport, geomorphology, salinity intrusion, and marsh evolution.
