Linking Back to Master Plan Objectives

  • Reduce economic losses from storm-based flooding
  • Promote a sustainable coastal ecosystem by harnessing natural system processes
  • Provide habitats suitable to support an array of commercial and recreational activities coast-wide
  • Sustain Louisiana’s unique heritage and culture

5. Provide a viable working coast to support industry.

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
slide19

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
