Environmental Modeling From Ransom Consulting, Inc.

Capturing the present to plan for the future.

Environmental modeling is both an art and a science. Ransom’s talented modeling specialists have the technical expertise, analytical training and creative vision to develop and present multiple scenarios that demonstrate the complex relationships between changing environmental elements over time.

These simulations often provide a view into the inner workings of an interrelated environmental system that would otherwise be impossible. In this way, the process of developing and calibrating an accurate environmental model reaffirms that existing (or conceptual) site assumptions are correct – but only if the model can precisely replicate current conditions.

Ransom consistently achieves this important baseline for clients by combining a proven process with powerful software modeling tools and extensive on-site experience, specifically in the areas of surface water modeling, groundwater modeling, sea level/coastal modeling and slope stability modeling.

Ransom Consulting: Connecting the dots through complex modeling.

With the confidence and expertise to tackle even the most complex, high profile projects, Ransom engineers and scientists have created dozens of complex models that provide critical insight into the areas of nuclear power plant site operation, decommissioning as well as coastal flood plain mapping.

In fact, Ransom’s professional modelers have provided groundwater modeling solutions for seven nuclear power plants and many CERCLA (Superfund), RCRA and large landfill sites across the United States.

In addition to these high profile sites, Ransom has modeled many other types of environments, such as:

Groundwater Modeling

Measuring the effects of well withdrawal on stream flow.
Identifying the potential for saltwater intrusion.
Forecasting the impact of septic systems on the regional aquifer.
Determining well water optimization and irrigation plans for commercial applications.

Coastal Modeling

Coastal circulation and flushing models created to evaluate the impact of aquaculture.
Large scale, wave modeling (FEMA) for coastal flood risk re-mapping.

Looking for help predicting the future of a groundwater or surface water regime? Trying to measure the impact of rising seawater levels on the long-term stability of a slope or beach? Contact Ransom today.
