This annual report for 2012
summarizes the major accomplishments, lists deliverables and reports, and
outlines the work plan for 2013 for the EDEN project. The EDENís primary
deliverable and product continues to be the EDENweb (http://sofia.usgs.gov/eden); the project website that provides all data, results, documentation, and
other project information for EDEN users.
I. Major Accomplishments
- Real-time, provisional, and final EDEN
surfaces are being produced and posted to EDENweb on schedule.
Surfaces currently posted on the EDENweb include:
for 1/1/2000 through 9/30/2011
for 10/1/2011 through 6/30/2012
for 1/1/1991 through 12/31/1999
for 7/1/2012 through current
processing of real-time EDEN daily water-level surfacing using V2 surface-water model:
automated use of ADAM software
for screening bad or missing data and for filling data gaps with
estimates using nearby gage data
newly formatted daily median files that tell users whether data for each
gage is measured, estimated, missing, or dry.
the support of USGS Greater Everglades Priority Ecosystem Science (GE PES)
funds, maintained operation of all
25 EDEN-funded gages and 9 coastal water-level gages originally
established for Tom Smithís SET project. GE PES funds filled the funding
gap when the EDEN budget was cut by 30% this FY.
EDEN daily water-level surfaces for 1/1/91 through 12/31/99 using hindcasted datasets completed in
to extreme low-water conditions in 1990, datasets need more analysis
prior to surfacing.
are cautioned about the quality of the water-level surfaces in the
vicinity of several gages where data is not consistent with previous
- The confidence index by Pearlstine and
others (2007) was tested using the newly revised V2 modeled surfaces. None
of the parameters, such as distance from a gage, were strongly correlated
with water-level differences measured at the benchmark network. Although a
confidence index map would provide users with a general guideline about
the accuracy of water levels modeled by EDEN, the parameters that define
the areas with lower confidence are not yet clear.
- A network analysis was conducted in
FY12 to evaluate whether selected water-level gages could be removed with
limited impact to the EDEN daily water-level surfaces. This analysis was
necessitated because the EDEN budget was cut by 30% in FY12 and expected
at this level in FY13 and beyond. Because the EDEN surface-water model
interpolates between water levels at gages, the confidence of the surfaces
depends on the location, distribution, and accuracy of the gage network.
The EDEN network analysis was coordinated with the SFWMD which conducted
an agency network analysis for the purpose of reducing their monitoring
budget for FY13.
- On 9/6, the EDEN project provided SFWMD and
USACE with final recommendations for gages that can be discontinued by
SFWMD and gages to be discontinued by EDEN.
- 11 SFWMD-funded gages and 10 EDEN-funded gages
are proposed for discontinuing that would not significantly impact the
EDEN water-level surfaces
- The EDEN project has secured sufficient funding
for FY13 ONLY to maintain 4 additional gages that would otherwise have
to be discontinued as a result of funding cuts.
- The final list of 6 EDEN-funded gages to be discontinued
starting 10/1/12 are:
- The SFWMD has coordinated their list of
potentially discontinued gages based on the EDEN gage list above. See
|Figure 1. Location of water-level gages in EDEN showing
gages discontinued or potentially discontinued in FY13. [larger version]|
- At the
request of the USACE, generated and posted water-level percentile plots for gages and tree islands in
WCA3A and 3B, and ENP to compare water levels under the Everglades Restoration Transition Plan (ERTP) with water levels under the Interim Operational Plan (IOP). The Tribes in the Everglades wanted to ensure that
the ERTP would not excessively overtop tree islands under the new
operational plan for the C&SF project. The daily water-level
percentile plots allow stakeholders to monitor water levels and a daily
email alert system informs them when current water levels reach specified
elevations at one or more gages or tree islands.

II. Support from other Programs and Funding Sources
Greater Everglades PES funds continue to support the
EDEN project by funding efforts by Paul Conrads (USGS-SC), Heather Henkel
(USGS-St. Pete), Bryan McCloskey (USGS-St. Pete), and Matt Petkewich (USGS-SC).
Additionally, GE PES provides some funds for Pamela Telis (USGS-Jacksonville) in
her role as project coordinator and liaison with the USACE.
Everglades PES funds -- The EDENapps
tools continue to offer EDEN users capabilities such as data viewing,
data retrieval, and data access and manipulation. Expansion of the EDEN
datasets and increased digital requirements require that the EDENapps
tools be upgraded to 64-bit processing on a Java-based platform. To take
advantage of the work funded by other GE PES funds, the National Wetlands Research Center (NWRC) in Lafayette, LA is working with EDEN to improve
capabilities of the existing tools.
Everglades PES funds -- Developed prototype application to generate synthetic hydrographs (EDEN-Syn)
for input into an EDEN model for subareas. The application will allow
users to create hypothetical hydrologic conditions for use in biological
Everglades PES funds -- Initiated development and testing of subarea models for water-level
surfacing; may be used to improve daily surfaces and allow for more
efficient testing of scenarios by users.
Everglades PES funds – Initiated development of a prototype Web
application for the display of current conditions and the change in conditions
for coastal water-level data described as Coastal EDEN. Presented at INTECOL/GEER 2012 conference to
gain feedback from users.

IV. Administrative (Contractual and Budgetary)
- As a
result of significant cuts to the RECOVER budget, the EDEN project
received a 30% reduction in the original budgeted amount for FY12. The FY12
funded amount was reduced.
of the recent EDEN products and developments, such as the ADAM software
and the new surface-water model, are expected to make handling of the data
and generation of water surfaces more efficient. The greatest impact of the
budget reduction is the discontinuance of water–level gages in the
Atlantic University (FAU, Dr. Zhixiao Xie) was funded by the EDEN project through
a CESU agreement in FY12 for:
methods and modeling schemes for sub-domain models for the EDEN study
V. FY12 Deliverables/Reports
has been updated throughout the year to provide data, metadata, and
documentation to MAP PIs and others.
Reports have been submitted on time to the RECOVER MAP coordinators.
VI. FY13 Workplan
This plan includes work elements funded from both RECOVER
MAP and USGS GE PES:
- Continue to generate and
post daily water-level surfaces of the Everglades for users.
- Document all the new work
via USGS series reports and journal articles.
- Revise EDEN data
- Implement ERTP email
- Complete and test subarea
- Implement webpage for
EDEN oligohaline zone (Coastal EDEN).
- Provide hydrologic
analyses and results for 2013 System Status Report to Congress.
- Collaborate with National
Wetlands Research Center for revisions to several of the EDENapps tools;
the EDEN DataViewer and TransectPlotter
- Develop EDEN-Syn and have
selected PIs test applications.
- Participate in the 2013
National Conference on Ecosystem Restoration (NCER) and present recent
EDEN analyses and results.
- Continue to work with
agencies that are monitoring water levels and develop a plan for creating
EDEN daily surfaces with fewer surface-water gages as funding cuts reduce
VII. Anticipated Needs and Issues
- The challenge for the
EDEN project, as with all RECOVER-funded projects, is to maintain a viable
effort despite the significant reduction in funding in 2012 and beyond.
Several of the recent products, such as the ADAM software and new surface-water
model, are expected to make the handling of the data and creation of water
surfaces more efficient. The anticipated reduction in the gage network is
likely to have significant impact on the EDEN process, however it our hope
that the data estimation programs and quality-assurance tools previously
developed will limit loss of confidence in the EDEN water-level surfaces
and other EDEN products.
VIII. Funding Status
EDEN project budget was cut by 30% for FY12 starting 10/1/11.
- As of
9/30/12, all of the FY12 funding under USGS IA #28 has been expended or
obligated. Invoices will be electronically submitted to the USACE within
the next few months.
Priority Ecosystem Science (PES) funding in FY12 was
to multiple principal investigators in support for EDEN research efforts.
This level of support is expected to be continued in FY13 with a potential
