• DAMP Physical Model addresses uncertainty and constraints in Everglades restoration to assist in the DECOMP PIR.

• DAMP Physical Model to refine our understanding of ecological benefits to support the selection of alternative plans.

• DAMP Physical Model to refine evaluation performance measures

• DAMP Physical Model to obtain a better scientific understanding of how “pristine” and “impacted” regions of the ecosystem will respond to hydrologic restoration

DAMP Physical Model: PurposeDAMP Physical Model: Purpose


• The DAMP Physical Model has been through eight iterations (Kia v1, v2; Lexus v1, v2, v3; Ferrari v1; and Prius v1 and v2).

• Consideration was given to the goals and concerns of all parties.

• The present design:• maximizes the uncertainties and hypotheses that

can be addressed• Incorporates some stakeholder concerns (e.g.,

restricting backfilling of canals to the L-67C)• Works within both current and future operational

constraints

• Evaluate performance measures for planning and designing DECOMP

• Reduce major uncertainties and a clearer understanding of potential “tradeoffs”

• Indicate the “ecological lift” associated with levee removal and canal backfilling

• Assess the hydrologic flow fields associated with different gap sizes

• Mechanistic understanding of the ecological processes associated with flow

• Ability to scale up to the landscape level
