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.

WAM Wave Model

Model Assumptions §  Time dependent wave action balance equation. §  Wave growth based on sea surface roughness and

wind characteristics. §  Nonlinear wave and wave interaction by Discrete

Interaction Approximation (DIA). §  Free form of spectral shape. §  High dissipation rate to short waves.

The global ocean wave prediction model WAM is a third generation wave model.

BUILDING STRONG®


SMS GUI for WAM

•  Create and visualize WAM grids and model results

•  Setup input/control files

•  Execute WAM Close-up view of WAM Grid

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.

16

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.

1.  Support for MORPHOS-PBL Cyclone Model*, ADCIRC’s internal Holland models and ATCF Best Track formats

2.  Ability to read/modify existing cyclone track and characteristics

3.  Ability to create cyclone track via “point-n-click” and add storm characteristics

4.  Ability to auto perturb cyclone data:

•  Speed •  Size

•  Track •  Intensity

Note: NOAA uses the ATCF Best Track.

The Earth System Modeling Framework

§  The ESMF has multi-agency buy in.

§  Having our models ESMF compliant makes them readily available to be linked with each other and with other agencies’ ESMF compliant models.

§  This leads to expanded collaborations and funding opportunities.

CSTORM-MS Coupling

Schematic for CSTORM-MS Version of Tightly Coupled

ADCIRC+STWAVE

•  Controller – 1 cpu •  Coupler – 1 cpu (1 coupler/STWAVE) •  ADCIRC/STWAVE share cpu’s

•  Model coupling between ADCIRC and STWAVE is performed using CSTORM-MS Couplers written in FORTRAN and MPI.

•  One benefit of using the ESMF coupling standards is that the individual codes stay virtually autonomous.

•  Specification of how the two models are to interact is done with a simple control file (mf_config.in).

•  If more than one STWAVE grid is involved, fine detail control over any overlapping regions can be specified by using a (merge_file).

•  Couplers take care of coordinate transformations and interpolations.
