CIRP April 2012 eNewsletter

Issue 29, April 2012

In this Newsletter:

Thanks to NAP, with help from NAB and NAN, for hosting our 13th Annual CIRP workshop!

The 13th Annual (38th sequential) Coastal Inlets Research Program (CIRP) workshop was held March 6-8 at the U.S. Army Engineer Philadelphia District, with attendance from Baltimore, Philadelphia, Charleston, Chicago, Galveston, and Norfolk Districts, the North Atlantic Division, and Stevens Institute of Technology. For the first time, the workshop was simultaneously presented via webinar to an additional 11 attendees from CHL, HDR, Inc., Roberge Associates, Applied Technology and Management, Galveston District, and the Narvik University College in Norway. The CIRP instructors included Tanya Beck, Mitch Brown, Ashley Frey, Honghai Li, Lihwa Lin, and Alex Sanchez and covered beginning Coastal Modeling System (CMS) and Surface-water Modeling System (SMS); the regional beach and inlet shoal evolution model GenCade, which is also in the SMS; and Advanced CMS. The CMS and GenCade are being advanced by the CIRP and Regional Sediment Management Programs to provide tools to evaluate engineering alternatives at inlets and adjacent beaches within a regional sediment management framework.

Did you miss the workshop? Announcing CIRP Webinar series.

Three webinars are planned for the summer of FY12:

  1. Coastal Modeling System (CMS) Basics (Jun 11-15)
  2. Advanced Topics with the CMS (June 18-22)
  3. GenCade (11-13 September)

All webinars will be from 1-3 pm CDT each day. Please register on the CIRP website (see link below) and we will send more information as these dates approach.

MixSed being implemented into CMS.

A collaborative effort by Drs. Earl Hayter (DOER) and Zeki Demirbilek (CIRP and DOER) is focused on expansion and enhancement of sediment transport modeling capabilities of the Coastal Modeling System (CMS). The planned improvements to CMS technology will allow CIRP to address sediment modeling and management (placement) needs of the USACE navigation O&M business line. Mixed (multiple-grain) sediment, cohesive sediment, and mud transport modeling capabilities that have been developed by DOER are being incorporated into the CMS. These new sediment modeling capabilities have been implemented in the explicit and implicit CMS-Flow models. Testing is in progress with laboratory and field data to verify and validate these new features of CMS. With such advanced new features of CMS, Districts will be able to evaluate and understand complex wave, non-stratified flow, and sediment processes and quantify their effects on coastal navigation, inlet, and harbor projects.

Pillar Point Harbor Modeling Phase II Study, CA.

The USACE District, San Francisco, and CIRP are presently conducting the coastal erosion numerical modeling Phase II study at Pillar Point Harbor, Half Moon Bay, CA. Following the completion of Phase I study in 2011 that included field data collection and numerical modeling of beach nourishment alternatives under combined hydrodynamic and wave conditions, the Phase II study is aimed to simulate the 50-year sea level rise conditions with and without Harbor scenarios using the National Research Council (NRC) Curves I and III. The model results will provide the technical information necessary for the Pillar Harbor and Half Moon Bay Stakeholders to better understand the existing coastal conditions and to look for solutions.

Comparison of CIRP Models – a new brochure!

Have you ever been confused about what the different models do? Or do you have problems explaining to your colleagues and partners why certain tools are required? CIRP has compared all of the models we support in a colorful brochure that you can find on our website: The brochure compares the advantages/disadvantages, time scales and platforms, and provides POCs for Bouss-1D/2D, CMS-Flow, CMS-Wave, GenCade, and PTM. Please download and share!


2012 Research Area Review Group (RARG) Meeting.

In case you were unable to attend the 2012 RARG Meeting in Vicksburg, MS, we have posted CIRP’s powerpoint, a powerpoint discussing future Statements of Need, and posters on our website for you to view and download as you wish ( Please take a look at these and let us know if you have any thoughts to share with us. Remember, you can always submit a Statement of Need for future R&D on the Navigation Gateway,, which we’ll discuss at next year’s RARG.
