Coastal Engineering & Modeling

Know what the coast is doing before you decide what to do.

Waves, tides, currents, sediment, storms, flooding and shoreline change all influence what is possible, what is practical and what will perform over time. Cummins Cederberg helps clients evaluate those conditions before critical decisions are made, translating coastal behavior into guidance for design, permitting, funding, infrastructure and maintenance planning.

Modeling that makes decisions clearer

A model should do more than show what may happen. It should help clients understand what matters, what changes the risk and what to do next.

Cummins Cederberg uses coastal, hydrodynamic, wave and numerical modeling to evaluate conditions, compare alternatives and test how solutions may perform in real coastal settings.

The model is only part of the answer.

The value comes from interpreting the findings, explaining the risk and defining the next step.

One site. Many forces at work.

Coastal engineering decisions rarely sit in one discipline. A shoreline strategy may affect permitting. A beach or dune project may depend on sediment behavior, habitat conditions and maintenance needs. A flood mitigation plan may need to balance funding, infrastructure priorities and future coastal change.

Cummins Cederberg’s coastal engineering and modeling team works closely with marine structural engineers, environmental specialists, regulatory professionals and planners, so technical insight is connected to the full project picture from the start.

Our coastal engineering and modeling services include:

Coastal Process & Hydrodynamic Modeling

Evaluating waves, tides, currents, water levels and sediment movement to understand how coastal systems behave and how proposed improvements may perform.

Three-dimensional CFD simulation of waves and flooding moving through a coastal neighborhood of buildings and trees

Advanced Numerical & CFD Analysis

Using advanced modeling tools to study complex coastal, marine and hydraulic conditions where detailed analysis is needed to support design or decision-making.
