  • Pre-Project and Post-Project Monitoring 

Coastal Engineering

Coast & Harbor Engineering (CHE) engineers apply state-of-the-art analysis methods and design tools to develop innovative, cost-effective, and constructible projects. CHE’s experience includes:

  • Shoreline protection
  • Sediment transport and morphology
  • Ecosystem restoration
  • Sea level rise
  • Storm impacts

Typical projects include the design of revetments, breakwaters, seawalls, jetties, and groins.


Coast & Harbor Engineering (CHE) engineers have demonstrated long-term success with dredging projects for:

  • Deepening harbors and waterways
  • Contaminated sediment clean-up and capping
  • Shoreline restoration
  • Mining

CHE engineers also apply numerical models to evaluate the fate of sediments, turbidity, and production rates during dredging and disposal operations.

Coastal Processes AND Modeling

Coast & Harbor Engineering (CHE) assesses coastal processes for project feasibility during planning, permitting, design, and for design optimization. CHE routinely analyzes physical processes including:

  • Waves, currents, winds, sediment transport and morphology
  • Water quality and turbidity
  • Tsunamis
  • Vessel hydrodynamic processes

Analysis includes development, validation, and application of advanced numerical modeling tools and analysis techniques, as well as commercial CFD codes. CHE also develops and applies machine learning techniques to quantify complex processes and enhance efficiency of numerical models.

Harbors AND Waterways

Coast & Harbor Engineering (CHE) engineers apply coastal engineering expertise to projects in ports, harbors, and marinas. Analysis and design efforts are performed to upgrade facilities, optimize design features, or mitigate undesired environmental conditions.

Typical projects include navigation channels and waterways, marine terminals, boat ramps, piers, and waterfront parks.


Coast & Harbor Engineering (CHE) has extensive expertise in the maritime field including:

  • Vessel hydrodynamic analysis
  • Ship maneuvering and berthing
  • Mooring analysis and seakeeping
  • Vessel wake prediction and transformation
  • Propeller wash and scour

Hydraulics AND Geomorphology

Coast & Harbor Engineering (CHE) provides engineering and numerical analysis of complex hydraulic and geomorphologic processes in estuaries, inlets, rivers, and marine environments. Analyses are performed as part of:

  • Navigation design
  • Flood control
  • Sediment control
  • Shoreline erosion protection
  • Water quality improvement
  • Delta formation and project-induced inlet evolution
