Overview & Objective(s):
The Everglades Depth Estimation Network (EDEN) supports the restoration of the Everglades by providing scientists and water-resource managers with current water-level and water-depth information for the freshwater part of the greater Everglades. The EDEN water-surface model uses the daily median values of up to 240 of the EDEN water-level gages to generate water-surface maps for the period January 1, 1991 to current. The target users are scientists examining trophic- and landscape-level responses to hydrodynamic changes in the Everglades. Other users include water-resource managers monitoring water levels and depths to meet mandated regulation schedules and wildlife-resource scientists managing habitat requirements for endangered species and other wildlife.

EDEN was initiated in 2006 with funding from REstoration COordination and VERification (RECOVER) Monitoring and Assessment Plan (MAP) program, a component of the Comprehensive Everglades Restoration Plan, through the US Army Corps of Engineers. That funding supports operation and maintenance of 25 gaging stations, data management for daily data of the EDEN network of about 250 gages, generation of the daily water-level surfaces, and partial funding for website development and maintenance for public access to the EDEN datasets.

Greater Everglades PES funding allows the project team to explore research topics that would otherwise not be funded by the USACE MAP. In addition, publications and website development are partially funded using PES funds making EDEN findings more broadly available nationwide.

Specific Relevance to Major Unanswered Questions and Information Needs Identified:
As scientists and managers attempt to restore the natural volume, timing, and distribution of sheetflow in the wetlands; consistent, documented, and easily accessible hydrologic data is essential. The EDEN datasets and tools are used to advise policy makers, planners, and decision makers of the potential effects of water management and restoration scenarios of the natural resources of the Everglades. EDEN's real-time data approach coupled with biological models, such as ATLSS and HSIs should help scientists: 1) evaluate how well the simulated relations that drive both biotic and abiotic models reflect and anticipate real-world events; and 2) examine biotic and abiotic responses to hydrodynamic change.

Status:
Major accomplishments in FY11 (PES funding plus USACE funding) were:

  1. Daily water-level surfaces posted to EDENweb. Surfaces currently posted include:
    1. Final surfaces for 1/1/2000 through 9/30/10
    2. Provisional surfaces for 10/1/10 through 6/30/11
    3. Real-time surfaces for 7/1/11 through current
  2. All water-surfaces 1/1/2000 through 6/30/11 have been generated using the new expanded and improved EDEN surface-water model (V2 model).
  3. Completed development of the EDEN surface-water model (V2). Revisions include:
    1. Model platform changes
    2. Expansion of the EDEN domain
    3. Development of subarea models for selected basins
    4. Changes to canal files
    5. Updated water-level gage data
    6. Model validation
  4. The ADAM (Automated Data Assurance and Management) software developed in FY11 is making data review and processing much more efficient and accurate.
  5. Development of an independent EDEN database that will supplement the USGS NWIS database for expanded EDEN capabilities.
    1. New gap-fill equations were derived based on longer period-of-record datasets
  6. Testing of confidence index maps for EDEN model water-level surfaces using V2 surface-water model.
  7. Rainfall and evapotranspiration (ET) data continue to be updated. Data currently posted include:
    1. Rainfall data for 2002 to 2011
    2. ET data for 1995 to 2010
  8. Support to several RECOVER principal investigators and agency representatives for EDEN data.
  9. Hindcasting of datasets for period 1990 through 1999 for all EDEN gages in freshwater part of Everglades.
  10. Initiated support from National Wetlands Research Center (NWRC) in Lafayette, LA to enhance and upgrade EDENapps tools.

Future Planning:

In 2010, the EDEN project was renewed for funding by the USACE (under RECOVER MAP funding) for the period April 2010 through March 2015. The project will continue to create and post daily water-level surfaces on a real-time basis for Everglades investigators.

Recent Products:

The EDEN team presented 7 posters and 8 oral presentations at numerous workshops and conferences. The EDEN team did not produce any USGS publications in 2011 because this year was a year for revision of several EDEN models and development of numerous new tools. FY2012 is slated for documentation and presentation of this information in USGS publications and conference proceedings.

Planned Products:

Task 1 – Support Everglades scientists by providing hydrologic data for ecological and biological assessments by 1) implementing the newly revised SW model and develop sub-area surface-water models, 2) incorporating ADAM into the data management process, 3) updating and posting rainfall and ET data, 4) conducting network analysis to test impacts of less dense network of gages, 5) implementing webpage for EDEN oligohaline zone, 6) participating in GEER 2012 conference and presenting recent EDEN improvement and results, 7) continuing to update and post rainfall and evapotranspiration (ET) data, 8) continuing to manage EDENweb on the SOFIA website, and 9) documenting results and post to EDENweb.

Task 2 – Complete creation of hindcasted water-level surfaces for the period 1990-1999

Task 3 – Improve and enhance the EDENapps tools by working with NWRC
