Refuge Modeling Performance Measures Development Overview
Explore the development of performance measures for refuge modeling presented by Mike Waldon in March 2010. The presentation covers hydrologic needs, proposed performance measures, model evaluations, and more for the Arthur R. Marshall Loxahatchee National Wildlife Refuge.

Arthur R. Marshall Loxahatchee National Wildlife Refuge TOC March 2, 2010 - Slides selected from ROG presentation: General Refuge hydrologic needs and a proposed performance measure for River-of-Grass alternatives Presented at: Science Workshop, River of Grass Project Planning Phase II January 27-28, 2010 Mike Waldon, Senior Hydrologist A.R.M. Loxahatchee Natl.

Refuge Hydrologic Performance Measures Possible PMs might measure 1. Reaching & holding high-stage (most years) 2. Recession rate (all years) 3. Reversals (all years) 4. Avoid extreme dry conditions (most years) Select #1 as first PM developed for ROG Other concerns may need to be addressed at a later project stage __________________________ 3
Model Evaluation Before using models to evaluate ROG alternatives for the Refuge, we should test if the models predicted PMs match observed PMs. ___________________________________ Evaluate 3 Refuge models: SFWMM South Florida Water Management Model v5.4 SRSM Simple Refuge Screening Model v4 MF DHI MIKE-FLOOD Refuge model v2 4
