ERDC’s Coastal Storm-Modeling System
(ERDC CSTORM-MS)
Next Generation Workflow
Not just
hurricanes and
not just in the
Gulf of Mexico.
Expandable and
upgradeable system.
Application of high-resolution, highly skilled numerical models in
a tightly integrated modeling system with user friendly interfaces
Provides for a robust, standardized approach to establishing the risk
of coastal communities to future occurrences of storm events.

STWAVE Version 6.0
STWAVE is a steady-state finite
difference model based on the
wave action balance equation.
The model is used to compute wave
transformation (refraction, shoaling,
and breaking) and wind-wave
generation.
14
Some features of the full-plane model include:
Wave transformation and generation on the full 360-deg plane.
Option for spatially variable winds and surge.
Option for spatially constant or spatially variable bottom friction.
Option for one-dimensional wave transformation on lateral boundaries.
