2 Presentation Overview 2 Why CSEC? What are we actually doing? How you can help?

3 CSEC Objectives 3 Transfer new science into practice faster Deliver science and engineering to improve coastal project life cycle systems performance and cost Develop business collaboratively Bring together capabilities, resources, and funding from multiple partners for an overall greater value than could be achieved separately Link academics to practice Student learning experiences Cultivate recruiting opportunities

4 USACE SWG Mission and Area of Responsibility 4 Navigation Flood Risk Management Regulatory Ecosystem Restoration Emergency Management Interagency & International Support 50,000 square mile district boundary 28 ports handling 500+ M tons of commerce annually 1,000+ miles of channels 750 miles shallow draft 270 miles of deep draft 367 miles of Gulf coastline M cubic yards/yr material dredged 16 Congressional districts 48 Texas counties 18 Coastal counties - bays / estuaries 9 watersheds 4 Louisiana parishes

5 Addressing Problems and Opportunities in the Coastal Protection and Restoration Program 5! EROSION Economic damage from coastal storm surge Inland shoreline erosion Gulf shoreline erosion Loss of T&E Critical Habitats (migratory bird habitat, critical T&E habitat, shellfish habitat) Loss of Natural Delta Processes Disrupted Hydrology

6 Contributors to Civil Works Program Risks and Uncertainties Stressors: Extreme storm water levels (rivers, coast) Dynamics of coastal shorelines, islands, wetlands, sediments, and debris Drought effects on water availability and quality Aging, outmoded, and/or exhausted infrastructure & equipment (e.g., locks, PAs, dredges) Program funding levels 6 Drivers: Relative sea level change Changing legislation/policies Resource availability (e.g., energy, land) Development patterns/rates and modifications to natural systems

7 Enhancing Strategic Partnerships for Delivering Value to the Nation 7 Texas coast shared visioning for alignment of agency values toward mutually desired outcomes Vibrant regional and national economy Resilient and sustainable communities Healthy, diverse, and functional ecosystems Driving progress through regularlyengaged partnering and governance Multi-agency participation (Local, State, Federal) Shared vision steering Identifying / resolving barriers to progress Team building, collaboration, and unified communications Articulating challenges and successes Building stakeholder awareness and support for action Supporting elected officials with needed information

8 Concepts of Resilience against Disturbances and System Sustainability 8 Scenario Scenario Engineering Environmental Community Sustainability issue? Goal is for Texas Coast to be: A resilient community with healthy ecosystem Positioned for sustainable economic growth Supported by strategic partnerships that support Non-Federal investment

9 SRRII Vision 9 Interconnected portfolio of partnered projects across business lines. Incorporates Regional Sediment Management (RSM), Engineering with Nature (EWN), Natural and Nature Based Features (NNBF), and Multiple Lines of Defense (MLD). Nested/networked infrastructure interoperating regionally to deliver broad spectrum of enduring economic, environmental, and social values. Value proposition for pursuit via inter-operational synergies: Transformed organizational technical, business, and management processes, High performing workforce culture, and Parties who understand, contribute to, and value the concepts and support infusion into practice.

10 CSEC Workshop Series Held workshops in AUG and NOV 2016 with next planned in APR Purpose: Explore and establish common interests for partnering on coastal science and engineering academics, research and development, and practice, for timely infusion of innovative technical products to support lifecycle coastal infrastructure systems management decisions in practice. Objectives: Become familiar with each others organizations and their future directions Identify crossover working relationships in coastal science and engineering Develop a partnering value proposition for achieving mutually held objectives Identify action items for joint organization follow up with future event planning

11 CSEC Program Management Plan Under Development Vision Intent Strategy Approach Goals Objectives Intended Capabilities and Products Path forward

12 Example CSEC Initiative: Galveston Bay Submerged Aquatic Habitat Restoration * (ft) * Low frequency acoustic survey to firm bottom. Depths below about 10 ft due to historic oyster shell mining. 1 Pilot demo under USACE Continuing Authority Program, Sec 1135 with TX GLO partnering interest (cost sharing, bay bottom land owner) ERDC R&D and TAMU academic opportunities for sediment and dredging engineering best practice development Bay bottom restoration enabling opportunity for shaping with resource conservation agencies Opportunity for beneficial use of dredged materials from ship berth and Houston Ship Channel maintenance and improvement

13 Example CSEC Initiative: ERDC R&D FY 17 Statement of Need (SON) Quantification of Biophysical System Vegetated Dune Performance of Natural and Nature Based Features (NNBFs) for Coastal Storm Risk Management (CSRM) Planning Studies Relevant to coasts that are: Exposed to tropical storms Low-lying Actively morphodynamic Figlus (2016) Experiencing the effects of relative sea level change (RSLC) Have extensive coastal development and inhabitation at risk Requirement for a technical capability that is reliable, quantifies uncertainties, and is able to be rapidly applied in studies If requirement not met, USACE will not be able to monetize performance and justify use of NNBFs, which has potential to be a challenge for project sustainability and resilience 1

14 Example CSEC Initiative: TAMU Capstone Student Project Innovative coastal storm surge barrier for: Meeting flood risk management requirements Adaptability for deep draft navigation requirements into the future Low impedance exchange of tidal energy, sediments, nutrients, salinity, and marine organisms Interdisciplinary technical requirements: Engineering and economic feasibility of concepts or project alternatives Detailed Design Plan of selected alternative Environmental loadings Hydrostatic and hydrodynamic loadings Structural and geotechnical requirements Economic and environmental impact 1 Jonkman (2016) Smith (2012)
