Coastal Process Modeling

Numerical models are deterministic tools that produce one solution for each set of boundary conditions. The Empirical Simulation Technique (EST) is the numerical computer simulation of multiple life-cycle sequences of systems such as storm events and their corresponding environmental impacts.

Using the EST procedure for a specific project generates risk-based frequency information that relates the effectiveness and cost of the project to the level of protection provided. These computer models are important design tools to develop shore protection projects based on storm conditions. They assist in benefit-cost analyses and can be tailored to conditions specific to different coastal areas.


Coastal Process Modeling

An example of an EST application described calculations of the frequency-of-occurrence relationship for storm-induced, horizontal recession of beaches and dunes in Brenard County, Florida.
