Louisiana’s Comprehensive Master Plan for a Sustainable Coast: 2012 Update Karim Belhadjali – Coastal Protection and Restoration Authority
2
Builds on Other Efforts 2
3
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 coast- wide 4.Sustain Louisiana’s unique heritage and culture 5. Provide a viable working coast to support industry. Linking Back to Master Plan Objectives

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
