Louisiana’s Comprehensive
Master Plan for a Sustainable
Coast: 2012 Update
Karim Belhadjali – Coastal Protection and
Restoration Authority

Linking Back to Master Plan Objectives
1. Reduce economic losses from
storm-based flooding
2. Promote a sustainable coastal
ecosystem by harnessing natural
system processes
3. Provide habitats suitable to
support an array of commercial
and recreational activities coastwide
4. Sustain Louisiana’s unique
heritage and culture
5. Provide a viable working coast to
support industry.
Key Components of 2012 Update
• Specific & Realistic Goals & Objectives
• Prioritized Project List
• Map showing the selected projects and what they
provide:
• Levels of risk reduction
• Levels of ecosystem services across the coast
• Extent and character of future landscape
• Detailed Implementation plan with:
• Schedule, Costs, Expected sources of funding
• Adaptive Management plan to guide implementation

Predictive Models Overview
• Eco-Hydrology
• Mass-balance box model
• Output – 16 variables
• stage, salinity, sediment, water quality
• Wetland Morphology
• 4 submodels - changes in the landscape
• Output – land change, fragmentation, elevation, SOC
• Barrier Shoreline Morphology
• Changes in tidal inlet area, location, area, and elevation
• Vegetation
• Probability of death / establishment of 21 vegetation
classes, per salinity, inundation
Predictive Models (cont’d.)
• Upper Trophic Level
• Habitat Suitability Indices
• 14 species and 1 functional group
• Storm Surge and Wave
• Coarsened AdCirc grid (used by USACE)
• Use output from wetland /barrier morphology and vegetation
to modify grid points
• Output – storm surge and wave elevation
• Risk Assessment (damage)
• Surge elevation, value of assets (commercial, residential,
infrastructure, strategic assets)
• Output – flood depths and resulting residual damages ($)
• Data Integration
• File naming, automations, model linkages and data transfer
