3 Boca Ciega Bay at Gulfport, FL Section 103 Storm Damage Reduction Project District: Jacksonville (Brandon Burch, PM) Coastal inundation in hurricanes and coastal storms Evaluate alternative protection measures using new Generation II Coastal Risk Model (G2CRM) Product: CHL will develop storm climatology input for G2CRM and provide SAJ model support, guidance and training Outcome: Identification TSP plan for reducing coastal inundation damages. On Schedule

4 Coastal Hazards System South Atlantic Regional Systems Management Study District: Jacksonville Probabilistic coastal hazard assessment in the Atlantic basin is complex (sparse occurrence of tropical cyclones) Projects require sophisticated statistical, meteorological, and hydrodynamic modeling Approach The Coastal Hazards System (CHS) is a data resource and web tool populated with coastal storm hazards and statistics High-resolution modeling and statistics will be generated for the SAD region and included in CHS Outcome: CHS tropical and extratropical storm suite, probabilistic modeling, astronomical tides, and sea level change scenarios covering the SAD region in high-resolution Hazard curves characterizing the exceedance probability of storm surge, water level, wave climate, wind, and other storm hazards Storm response results can be used for RSM implementation Project initiated summer 2016 Efficient Storm Sampling Tropical Cyclones (Synthetic) Development of JPM Storm Set Characterization of Storm Climate (Forcing) Climate and Hydro Modeling PBL Cyclone Model (Wind and Pressure Fields) Extratropical Cyclones (Historical) Development of Composite Storm Set WAM (Regional) Water level (storm surge, astronomical tide, SLC) Currents Wind speed, direction Wave height, peak period, direction ADCIRC CSTORM- Coupler STWAVE (Nearshore) CHS Response Statistics Combined Joint Probability Annual Exceedance Probability Confidence Levels

5 Alabama Barrier Island Restoration Assessment Task 5.3 Katrina Cut Life-Cycle Structure Response Modeling District: Mobile National Fish and Wildlife Foundation (NFWF) and Alabama Department of Conservation and Natural Resources projects are designed to remedy harm or reduce the risk of future harm to natural resources that were affected by the 2010 Deepwater Horizon oil spill Approach Model life-cycle response of Katrina Cut rubble mound breakwater including structure profile evolution, morphology change and wave response Outcome: Probabilistic model of storms, validated morphology/structure response model, risk of structure failure Model development completed in 2016 Final modeling (mid 2017)

6 Sand Island (DA10) Field Work District: Mobile (MsCIP) Study: Understand fate of dredged material placed within the Sand Island littoral zone site Assist in verifying the optimum placement zone for future dredging/placement operations Approach Placed instruments offshore and landward of the nearshore placement area, just west of Petit Bois Island Outcome: Sediment tracers placed Surveys conducted Modeling and report out (FY17)

7 Vilano Beach Nearshore Berms District: Jacksonville, Wilmington Study: 150,000 cy dredged from St. Augustine Inlet and placed in the nearshore Approach Created two berm shapes (elongate and mound) Monitor the nearshore berms (SAJ assisted) Worked with SAW s dredge Murden personnel to create placement plan Outcome: SMT predicted onshore movement. Surveys confirmed onshore movement Grain Size (mm) Predicted Sediment Migration % Offshore % Onshore % Onshore % Onshore % Onshore

8 Oregon Inlet Radar Inlet Observing System (RIOS) District: Jacksonville, Savannah, & Charleston Low-use channel with significant operational costs for hydrographic surveying & dredging Hourly measurements using RIOS to provide near-real-time support of surveying, dredging, and navigation Expected outcome/products: Bathymetry Shoal and beach Morphodynamics (for strategic dredging) Recommended navigation routes and conditions Hourly data in CHL webpage for SAW personnel Oregon Inlet Navigation Routes and Conditions shoals & breaking waves

9 Charleston Harbor Shoreline Change Data Collection and Analysis District: Charleston Long-term shoreline change monitoring program during Harbor Deepening Shoreline change analysis from historical data followed by instrumented monitoring of shoreline position and vessel traffic Expected outcome/products: Document shoreline change rate Periodic analysis of changes to shoreline change rate and vessel traffic Incorporating review comments Preparing equip. purchase BUILDING STRONG

10 Charleston Harbor Anchorage Basin Use Analysis District: Charleston Objective user analysis to support shortening 10-year dredging cycle for anchorage. AISAP used to perform time-series analysis of vessels using the anchorage basin: identified growth of unique users and dwell time before and after construction Expected outcome/products: Summary briefing was presented in NOV 16 Completed

11 Section 103 Sediment Characterization of ODMDS District: Port Everglades (SAJ) & Pascagoula Harbors (SAM) Sediment characterization of Section 103 projects (maintenance/deepening) Collect (CHL) and analyze (EL) material from the project sites and the ODMDS(s) Using vibracore, grab sampling, and pumping of site water EL performs toxicological and bioassay analysis Expected outcome/products: Comprehensive sediment characterization of projects summarized in a report submitted to the EPA Sampling and Analysis Plan (SAP)/Quality Assurance Project Plan (QAPP) written and submitted to EPA for review In the process of mobilizing personnel and equipment to complete the first two projects BUILDING STRONG

12 Tools for Regional Resilience Assessment Hurricane Matthew and the Southeastern Seaboard District: Jacksonville, Savannah, & Charleston More standardized applied metrics needed to define the resilience of the marine transportation system (MTS) CHL tools can provide unique ways of measuring the impacts of disruptions on ports and federal channels. Hurricane Matthew as test case to assess the utility of these tools Expected outcome/product: Documentation and support for future analyses of MTS resilience Model data collected with analysis and interpretation under way Net Vessel Counts Shoaling impacts in $

13 Networked Port Resilience Study of Federal Components of Marine Transportation System Resilience District: Jacksonville, Savannah, & Charleston Large scale resilience studies remain theoretical in application and fail to set up frameworks/foundation for real-world analysis, especially for considering overall system. Work with members of the Resilience Integrated Action Team of the Committee on the Marine Transportation System to set up a pilot region study that: Develops an inventory of datasets and information on the Federal components of resilience for the MTS Enhances understanding of the interdependencies and vulnerabilities of the MTS Tests the resilience of the system through a series of case studies Expected outcome/product: ERDC/CMTS report on approach case study findings Inventory mostly complete Integrated Action Team engaged on example collection and draft of approach in progress. Analysis underway
