“Overview of CIRP Regional Sediment Management Tools” held in Conjunction with Regional Sediment Management Workshop
On 26 March, CIRP researchers Ashley Frey, Mitch Brown, and Julie Rosati gave an overview of CIRP tools for Regional Sediment Management (RSM), including GenCade and the Coastal Modeling System (CMS-Wave and CMS-Flow) with application of the Particle Tracking Model (PTM). Ashley and Mitch discussed application of GenCade to Galveston, TX and the CMS to Newburyport, MA, respectively. Jason Engle and Kelly Legault from the Jacksonville District discussed application of CMS for RSM in northeast and southwest Florida, and application of sediment budget tools in conjunction with these studies. Twenty-one attendees from 8 Districts participated in the half-day workshop.

Depth of Closure Web Database Available on CIRP Website
The CIRP-Inlet Geomorphology work unit has created a database containing depth of closure (DOC) values as associated with each Wave Information Study (WIS) station hindcast that is available along each coast of the United States, including the Great Lakes. The DOC was calculated using several different methods (e.g. Birkemeier, 1985; Hallermeier, 1981; etc.) for comparison. The database is available on the CIRP Website – Products – US Depth of Closure Info (http://cirp.usace.army.mil/products/depth-of-closure.php) so that coastal engineers and planners may use the DOC calculations for beach and nearshore projects. In the future, the data will be available in the form of an interactive webtool in the CIRP Portal.

Galveston Island Sand Management Plan
ERDC recently completed the Galveston Island Sand Management Plan for the Galveston Park Board which developed a long-term plan to manage the sands and beaches of Galveston Island, Texas. To better understand the physical processes, an updated sediment budget for the island was completed and incorporated in the Sediment Budget Analysis System (SBAS). GenCade was used to calculate shoreline change for a time period of 50 years considering various beach fill, backpassing, and structural alternatives. The sand management alternatives ranged from the present plan of reacting to storms or emergencies to a comprehensive beach fill along all of Galveston Island with backpassing plants on each end of the island. ERDC presented the plan at a Galveston Park Board meeting in November 2014 and submitted the written plan at that time. ERDC is investigating options to publish this study as a Technical Report or Special Report.

Chief Research Scientist of Republic of Korea Environment Institute (KEI) Visits ERDC
Dr. Kwangwoo Cho, Chief Research Scientist of KEI under the Office of Prime Minister of ROK visited ERDC Vicksburg, 22-23 September. CIRP and KEI are cooperating on a pilot study, “Vulnerability Assessment Model of Climate Change: Application to Korean Coast”, to apply the CIRP's Coastal Modeling System for an upcoming comprehensive impact assessment and development of adaptation strategies related to sea level rise and climate change at the national level in Korea. The purpose of the visit was to gain a better understanding of ERDC’s research on quantitative risk assessment regarding existing and future coastal development. During his visit, Dr. Cho discussed the ongoing pilot study with CIRP scientists and engineers and he also met with other researchers from Coastal and Hydraulics Laboratory, Environmental Laboratory, and Geotechnical and Structures Laboratory and discussed potential future collaborations between KEI and ERDC.

CIRP FY14 Products and FY15 Plans
Curious about what CIRP produced in FY14? We had 17 publications (6 TRs, 7 TNs, 4 JPs), 5 webinars, workshops, or video clips; and produced two upgrades or new products. For more information, please see the CIRP website: http://cirp.usace.army.mil/. In FY15, CIRP will be initiating several new R&D thrusts: inlet breaching (Statement of Need (SoN) 2014-N-14), long-term morphology change including the effects of relative sea level rise on navigation projects (2008-N-6, 2012-N-11, 2011-N-4), dune resiliency and recovery (2014-N-10, and partially addressing SoN 2014-N-7), advances to nearshore placement evolution and predictive capability (2013-N-6, 2011-N-15), and advances to the Coastal Modeling System including capability to deepen channels (e.g., dredge) during simulations. Research and Development will continue in the Automated Information Service (AIS) Analysis Package (AISAP) (2012-N-5), Channel Portfolio Tool (CPT; 2009-N-8), Coastal Structure Management, Analysis and Ranking Tool (CSMART), and WaveNet tools (2011-N-10).
