LOSOM - Pareto Re-Evaluation

---

Site Update 2021-05-11

The Data

The data presented here is a subset of the 27k Pareto runs (file: LOSOM_CPA_PARETO_27k_2020Nov10.xlsx) produced to select potential plans for the LOSOM effort.

The data contains the RSM-BN input parameters, output performance measures, and describes methods used to select the best performing simulation(s). The original worksheet was produced in the fall of 202 by the SFWMD H&H Modeling Section and the Interagency Modeling Center, as directed by the USACE for the LOSOM project.

• Team: Pattie Fulton, Walter Wilcox, Cal Neidrauer, Alaa Ali, Raul Novoa, Randy VanZee, Hal Correa, Sashi Nair, Jenifer Barnes, Maliha Ahmed, Danielle Morancy, Clay Brown, Sandeep Dabral

Selected Plans

An array of balanced plans were considered and presented below. For informational purposes the plan used in Iteration 1 modeling was also provided (Model_Index 2C_2193).

Metrics specific to Caloosahatchee River Estuary (CRE), Regulatory discharges (to CRE and St Lucie Estuary), Lake Okeechobee Stage envelope and flow south.

Water Supply Specific Metric.

Percent difference relative to FWO (LSM25B) for selected performance measures.

Multi Criteria Decision Analysis

• Multi-Criteria Decision Analysis (MCDA) presented by USACE PDT to evaluate iteration 1 plans.

• Methodology to synthesize sub-objective performance for each alternative based on key performance metrics identified by sub-teams.

• Used here to evaluate the selected plans and only focuses on Caloosahatchee Estuary, Lake Okeechobee, South Florida Ecology and St Lucie Estuary metrics as presented by USACE (12-April 2021 - PDT workshop).
