CPT Upgrades and CPT-CSMART Merger
Several functional upgrades and refinements have been added to the Channel Portfolio Tool (CPT). These updates include a nested tree interface for simplified selection of multiple sub-reaches and commodity groupings. A channel condition upload feature is also under development to provide authorized users with the ability to submit recent channel controlling depths for inclusion within CPT. These data will allow for improved estimates of disrupted waterborne commerce due to shoaling in navigation channels. Additionally, The Coastal Structures Management, Analysis, and Ranking Tool (CSMART) is being integrated into the CPT web-based platform, giving users a one-stop shop for coastal navigation asset management. The developmental version of CPT is currently available online to Corps users at: https://itlgis01.usace.army.mil/CPTWeb/.

RSMP and CIRP R&D Collaboration
The Regional Sediment Management Program (RSMP) has leveraged several CIRP R&D initiatives in 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.
The CMS-Wave model has recently been upgraded to include provision for specifying a full-plane wave representation, available for standalone (wave modeling only) and inline code with CMS-Flow (coupled 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.

Numerical Model Support Program (NMSP) and CIRP
Soon it will be time for Districts to specify numerical models they rely on and are willing to support under the NMSP. This funding goes toward assistance in helping to run models, in upgrading them based on 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.

GenCade Version 1 Release in SMS 11.0
GenCade is a model designed to address Regional Sediment Management (RSM) for a large coastal coverage and long-term temporal extent, and it connects sediment sources and sinks, either natural or 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.
Beta Release of the Surface-water Modeling System (SMS) Version 11.0
The beta release of SMS 11.0 is scheduled for this fall. The interface will include a more user friendly model controls, and the option to use a quadtree mesh. The interface will include a beta version of CMS v4.0. The new inline CMS has an improved coupling between CMS-Wave and CMS-Flow, a full-plane version of CMS-Wave, improved and enhanced sediment transport, spatially variable winds and atmospheric pressure, and improved wave-current interactions. The beta release will include the CMS v4.0. The latest beta release of CMS v4.0 can be obtained from http://cirp.usace.army.mil/products/index.html.

First notice on FSBPA CIRP Workshop
The 12th Annual CIRP workshop will be held 7-9 February 2011, prior to the Florida Shore and Beach Preservation Association (FSBPA) Conference at the Hyatt Regency Jacksonville-Riverfront, Jacksonville, FL (see: http://www.fsbpa.com/techconference.htm). The CIRP workshop will focus on recent advances in inlet and adjacent beach technology, including the regional shoreline and inlet evolution model, GenCade; the Regional Morphology Analysis Package (RMAP) for analyzing regional data sets; a review of methods to assess the influence of inlets along adjacent beaches (Section 111 procedure review); and Practical Guidance for applying the Coastal Modeling System (CMS) discussing how to calibrate and validate a project application. Sessions will feature hands-on examples with models and tools. Two optional evening sessions are planned: (1) the Coastal Modeling System for Advanced Users (Monday evening and optional Tuesday break-out session); and (2) for Corps personnel only, the Channel Portfolio Tool (CPT) and the Coastal Structures Management Analysis and Ranking Tool (CSMART) (Tuesday evening). Watch the CIRP website for more information about the workshop in the coming months.
