Floodplain Analysis, Mapping, and Management Services
Rivers and their associated floodplains serve a variety of important natural functions including conveying water and sediment, storing flood waters, and providing diverse habitat. Floodplains, however, are also prime areas for agriculture and commercial and residential development that may be prone to flood damage. Floodplain analysis and management seeks a balance between conserving natural functions and reducing flood ...

Sedimentation Engineering Services
Sedimentation engineering studies are often essential to successfully design and manage engineering works along rivers, lakes, and reservoirs that may be affected by erosional processes and sediment transport and deposition. Quantitative sedimentation engineering also helps meet environmental objectives, including conserving and improving aquatic habitat and restoring physically and biologically degraded ...

Recreational Hydraulics Services
Many major cities and communities worldwide are revitalizing their river corridors for recreation. In many cases, replacing dangerous hydraulic structures with naturalized 'whitewater parks' has provided many public benefits. Although usually designed for canoeing and kayaking, 'playwave' features are fun for swimming, wading, and viewing, and also provide fish ...

Pump Station Hydraulic Design Services
NHC provides hydraulic analysis and design recommendations for operating pump station sumps and wet wells. Pump stations that operate with unsuitable approach flow hydraulics can suffer damage from cavitation, vibration, and bearing wear, and may be unable to meet design requirements. Focused analysis using physical and CFD modeling provides key information for optimal pump design, thus improving performance, reducing maintenance costs, and increasing the ...
