Model Documentation Reports

Comprehensive documentation of the public releases of our models...


-- For the report (Mitsch, Band and Cerco, 2007) of the Independent Peer Review Panel who recommended the use of ELM v2.5 applications to help evaluate Everglades restoration plans: see the ELM application page at the South Florida Water Management District, or a copy of that report found here. Subsequent model versions have improved upon the capabilities and performance of the model (see documentation reports below).


ELM v2.8.6 Documentation Report (version used in CERP ASR project: 500 m resolution regional application, historical calibration/validation; also see Projects: Everglades regional 500m cal/val )

Fitz, H. C. 2013. Documentation of the Everglades Landscape Model: ELM v2.8.6 - Sulfate Module. Ft. Lauderdale Research and Education Center, IFAS, University of Florida, Ft. Lauderdale, FL http://ecolandmod.ifas.ufl.edu/publications. 128 pages.

Note: this is an update to the below ELM v2.8.4 and v2.8.3 reports, providing documentation of the design and performance of the model version used for the CERP ASR project. Like the prior update reports, this report does not update Chapters that remain unchanged from ELM v2.5. Thus, relative to v2.5, the ELM v2.8.6 report only includes a new Preface (and Goals & Executive Summary), Data Chapter 4, Model Structure Chapter 5, and Model Performance Chapter 6. See the ELM v2.5.2 report for information on the Everglades, conceptual models, uncertainties, and model refinement paths.

        

ELM v2.8.4 Documentation Report (version used in CERP Decomp project: 500 m resolution regional application, historical calibration/validation; also see Projects: Everglades regional 500m cal/val )

Fitz, H. C. and R. Paudel. 2012. Documentation of the Everglades Landscape Model: ELM v2.8.4. Ft. Lauderdale Research and Education Center, IFAS, University of Florida, Ft. Lauderdale, FL http://ecolandmod.ifas.ufl.edu/publications. 364 pages.

Note: this is an update to the below ELM v2.8.3 report, providing more comprehensive water quality documentation for the model version used for CERP Decomp project. Like the v2.8.3 report, this report does not update Chapters that remain unchanged from ELM v2.5. Thus, relative to v2.5, the ELM v2.8.4 report only includes a new Preface (and Goals & Executive Summary), Data Chapter 4, Model Structure Chapter 5, Model Performance Chapter 6, and User's Guide Chapter 10. See the ELM v2.5.2 report for information on the Everglades, conceptual models, uncertainties, and model refinement paths.

        

ELM v2.8.3 Documentation Report (500 m resolution regional application, historical calibration/validation; see Projects: Everglades regional 500m cal/val )

Fitz, H. C. 2009. Documentation of the Everglades Landscape Model: ELM v2.8. Ft. Lauderdale Research and Education Center, IFAS, University of Florida, Ft. Lauderdale, FL http://ecolandmod.ifas.ufl.edu/publications. 214 pages.

Note: uses the same format as the below ELM v2.5.2 Documentation Report, but does not update Chapters that remain unchanged from ELM v2.5. Thus, the ELM v2.8.3 report only includes a new Preface (and Goals & Executive Summary), Data Chapter 4, Model Structure Chapter 5, Model Performance Chapter 6, and User's Guide Chapter 10. See the ELM v2.5.2 report for information on the Everglades, conceptual models, uncertainties, and model refinement paths.

        

ELM v2.8.1 Documentation Report: Application of ELMwca1 v2.8 (200 m resolution subregional application to WCA-1, including historical calibration/validation results, future scenario results, etc; see Projects: Everglades WCA-1 200m )

Fitz, H. C. 2008. Documentation of the Everglades Landscape Model: Application of ELMwca1 v2.8. Final report submitted to South Florida Water Management District, Everglades Division. West Palm Beach, FL. http://ecolandmod.ifas.ufl.edu/publications. 236 pages.

Note: uses the same format as the below ELM v2.5.2 Documentation Report, but does not update Chapters that remain unchanged from the regional ELM v2.5.2 application. This ELM v2.8.1 application report includes a new Preface, Introduction Goals & Objectives Chapter 1, Data Chapter 4, Model Structure Chapter 5, Model Performance Chapter 6, and Model Application Chapter 8. See the ELM v2.5.2 report for information on the Everglades, conceptual models, uncertainties, and model refinement paths.

        

ELM v2.5.2 Documentation Report (1 km resolution regional application, historical calibration/validation; see Projects: Everglades regional 1km cal/val )

Fitz, H. C., and B. Trimble. 2006. Documentation of the Everglades Landscape Model: ELM v2.5. South Florida Water Management District, West Palm Beach, FL (Reviewed by independent expert panel, reported at http://my.sfwmd.gov/elm, or a copy of that report can be found here). 664 pages.
