== RSMP and CIRP R&D Collaboration ==
== Reminder: Coastal Sediments 2011 Conference Abstracts Due 1 April 2010 ==


The Regional Sediment Management Program (RSMP) has leveraged several CIRP R&D initiatives in
Coastal Sediments 2011 will be convened May 2-6, 2011 in beautiful Miami, FL, at the Miami Regency Hyatt. Short courses will be held on Monday, May 2, followed by 3 days of the technical specialty conference. Several post-conference tours will be offered on Friday, May 6. Abstracts will be accepted through 1 April, 2010. Topics of interest include those related to the conference theme, "Bringing Together Theory and Practice," and other topics listed on the website. An abstract template, complete list of topics, and other information is available at http://coastalsediments.cas.usf.edu/index.html. We urge you to submit abstracts on case studies and other work to this high-level technical specialty conference for coastal engineers, geologists, and shallow-water oceanographers. The conference is competitive, so showing example results in your abstract will likely help toward selection.
FY10, including (1) Coastal Modeling System (CMS) applications at Ocean Beach, CA, Ship Island, MS,
Coast of Rhode Island, and St. Augustine, FL; (2) GenCade applications at Point Lookout, NY, and Onslow
Bay, NC; and (3) investigation of nearshore berms at Ft. Myers, FL, and an offshore berm at Galveston,
TX. The RSMP and CIRP have synergistic missions in maintaining and restoring regional littoral transport
magnitudes and pathways (RSMP) and improving management of coastal inlets (CIRP); both programs
seek to reduce Operation & Maintenance costs. These collaborative studies will be briefed at the Annual
Regional Sediment Management Workshop to be held in St. Augustine, Florida, September 14-16.

== CMS-Wave Upgrade ==
== CIRP-RSM-MCNP Collaboration on Nearshore Berms ==
The CIRP is teaming with the Regional Sediment Management (RSM) and Monitoring Completed Navigation Projects (MCNP) Programs, as well as with the Jacksonville, Mobile, and San Francisco Districts to monitor and/or model nearshore berm performance and develop guidance for their placement. This R&D is in response to a Statement of Need submitted to the Navigation Gateway that guidance is lacking for design of berms, possibly of mixed grain sizes, placed in the nearshore to provide a source of littoral sediment to the adjacent beaches while minimizing transport into the adjacent navigation channel. Nearshore berms may offer an economical disposal method, but capability to predict performance is presently limited. For many inlets, sediment dredged from navigation channels includes a mix of fines (clay and silt) and sand, and it is unsuitable for direct placement on adjacent beaches. Berms may provide a way to feed sand to beaches while winnowing fines to the offshore. Berms adjacent to navigation channels at Galveston, TX; East Pass, Destin, FL; Fort Myers Inlet, FL; and San Francisco Bay, CA are being studied through field data collection and/or numerical modeling to understand how sediment is mobilized and transported. If you have experience with berms or an ongoing nearshore placement of dredged sediment, please let us know about your projects.


The CMS-Wave model has recently been upgraded to include provision for specifying a full-plane wave
{{POC|Julie Rosati|Julie.D.Rosati@usace.army.mil}}<br>
representation, available for standalone (wave modeling only) and inline code with CMS-Flow (coupled
{{POC|Nick Kraus|Nicholas.C.Kraus@usace.army.mil}}
wave, current, and sediment transport modeling). The full-plane version generates and propagates
waves, and interacts with the current field in all wave directions. The full-plane capability is ideal for
simulations of islands or of a regional coastal-inlet-bay system for which wind waves are generated on
the bay independently of the coastal wave transformation. This version includes the capabilities of
applying spatially variable wind and surge fields. Users can specify either the full-plane or half-plane
mode in an application. The runtime in the full-plane mode is approximately twice of the half-plane
mode. The new CMS-Wave can access multiple processors in today's PC technology to expedite a largedomain
simulation and is available for download from the CIRP website under Products | CMS | Explicit |
CMS-Wave, http://cirp.usace.army.mil/products/index.html.

== Draft CHETN - Flowlane Disposal ==


== Numerical Model Support Program (NMSP) and CIRP ==
Flowlane disposal is placement of dredged sediment in a natural inlet thalweg having a strong current such that the material is transported out of the area. Flowlane disposal is beneficial in returning sediment that was trapped in a harbor or navigation channel to the littoral system and, therefore, can be part of a regional sediment management plan. This CHETN describes a collaborative strategy with a Federal navigation project sponsor at Willapa Bay, WA, for conducting operation and maintenance dredging and disposal activities including flowlane disposal. A collaborative strategy increases opportunities for securing funding to conduct maintenance dredging and promotes responsiveness to local sponsor needs and capabilities. Dredge-ready or shovel-ready maintenance dredging plans compete well and may possibly be more competitive for future Federal funding presently unavailable through the U.S. Army Corps of Engineers (USACE) alone for low-use navigation projects.


Soon it will be time for Districts to specify numerical models they rely on and are willing to support under
{{POC|(Seattle District)Hiram Arden|Hiram.T.Arden@usace.army.mil}}
the NMSP. This funding goes toward assistance in helping to run models, in upgrading them based on
{{POC|(ERDC) Nick Kraus|Nicholas.C.Kraus@usace.army.mil}}
District needs, and in improving documentation. The CIRP is considered a leader in technology transfer,
and we need your help through the NMSP. Model improvements easily outpace publications in technical
reports, and to address this time lag we have set up a Wiki environment so that we can make updates
easily AND interact with users. Users can also publish experiences and case studies to the wiki. Please
see http://cirp.usace.army.mil/wiki/Main_Page.

== 3-D Sediment Transport Modeling and Application for Ocean Beach, CA. ==


== GenCade Version 1 Release in SMS 11.0 ==
The CIRP and the San Francisco District are presently conducting a 3-D hydrodynamic and sediment transport study with the Coastal Modeling System (CMS) to evaluate erosion at Ocean Beach, CA, under the auspices of the Regional Sediment Management (RSM) Program. Ocean Beach is located on the coast of San Francisco to the south of the Golden Gate in the shadow of the San Francisco ebb tidal delta. The flow field is highly three-dimensional there, characterized by large waves, strong tidal current, up welling and down welling, and engineering activities including maintenance of the navigation channel through the delta. The study will integrate a wide range of field data collection, including historic bathymetry surveys of the ebb delta evolution, to simulate the hydrodynamics and sediment transport with emphasis on how these processes relate to erosion at Ocean Beach. The result from the study can help guide future navigation O&M and related dredging activities, beneficial use of dredged material for nearshore and onshore displacement, beach protection, sand dune restoration, as well as decision making for RSM, enhance cross-mission benefit, and reduce project life-cycle costs.


GenCade is a model designed to address Regional Sediment Management (RSM) for a large coastal
{{POC|(ERDC)Lihwa Lin|Lihwa.Lin@usace.army.mil}}
coverage and long-term temporal extent, and it connects sediment sources and sinks, either natural or
{{POC|(San Francisco District) Frank Wu|Frank.Wu@usace.army.mil}}
mechanical, between inlets and beaches. Gencade helps answer questions posed in planning and
engineering levels by combining (1) the engineering power of GENESIS, (2) the regional processes
capability of the Cascade model, and (3) new enhancements specific to regional sediment management
needs within the Surface-water Modeling System interface. Version 1 of GenCade is to be released in the
Beta release of SMS 11.0 this fall, and will include the functionality of a georeferenced environment
together with accessibility to other U.S. Army Corps of Engineers numerical models. CIRP is presently
applying GenCade for two different RSM studies, one at Point Lookout, NY, and the other at Onslow Bay,
NC. The study at Point Lookout has evaluated future nourishments and enhancement and additional
structures along the eastern first mile of the Long Beach Island Coastal Planning Project. The Onslow Bay
study covers a much larger spatial extent (100 miles) and is evaluating sand sources and sinks between
inlets and barrier islands, as well as the infilling time scales for borrow sites being considered for beach
placement.

The Ria Formasa lagoon and barrier island chain is located along the coast of Portugal -- http://en.wikipedia.org/wiki/Ria_Formosa. The area has been well studied because of the landward migration of the barrier islands, choking the lagoon, and its breach and overwash over relatively low barrier islands. The video shows a recent breach in a barrier there.
