Abstract

The Everglades Depth Estimation Network (EDEN) is 

an integrated network of real-time water-level gaging stations, ground-elevation models, and water-surface elevation 

models designed to provide scientists, engineers, and waterresource managers with current (2000–2009) water-depth 

information for the entire freshwater portion of the greater 

Everglades. The U.S. Geological Survey Greater Everglades 

Priority Ecosystems Science provides support for EDEN and 

their goal of providing quality-assured monitoring data for 

the U.S. Army Corps of Engineers Comprehensive Everglades Restoration Plan. To increase the accuracy of the daily 

water-surface elevation model, water-level estimation equations were developed to fill missing data. To minimize the 

occurrences of no estimation of data due to missing data for an 

input station, a minimum of three linear regression equations 

were developed for each station using different input stations. 

Of the 726 water-level estimation equations developed to 

fill missing data at 239 stations, more than 60 percent of the 

equations have coefficients of determination greater than 0.90, 

and 92 percent have an coefficient of determination greater 

than 0.70. 

Introduction

The Everglades Depth Estimation Network (EDEN) is 

an integrated network of real-time water-level gaging stations, 

ground-elevation models, and water-surface elevation models 

designed to provide scientists, engineers, and water-resource 

managers with current (2000–2009) water-depth information 

for the entire freshwater portion of the greater Everglades 

(Telis, 2005, 2006). EDEN is presented on a 400-squaremeter (m2

) grid, and EDEN offers a consistent and documented dataset that can be used by scientists and managers to 

(1) guide large-scale field operations, (2) integrate hydrologic 

and ecological responses, and (3) support biological and 

ecological assessments that measure ecosystem responses to 

the Comprehensive Everglades Restoration Plan (CERP; U.S. 

Army Corps of Engineers, 1999). The target users of EDEN 

are biologists and ecologists who can use the information to 

examine trophic-level responses to hydrodynamic changes 

in the Everglades. The EDEN database is a 9-year dataset of 

baseline conditions prior to the implementation of the CERP 

and offers investigators a single repository for historic hourly 

water-level data.

To estimate water depths in the greater Everglades, geographic information system (GIS) models have been developed to determine the ground elevation and water-surface 

elevation for the freshwater portion of the Everglades. The 

water-depth estimates are the differences between the two 

surfaces. Data to support the ground-elevation model include 

elevation measurements at more than 50,000 sites (Desmond, 

2003). Data to support the water-surface model include continuous water levels at 256 stations (fig. 1), including 25 stations that were added to the EDEN database in 2006. The 

water levels for the 25 recently added stations were hindcasted 

to 2000 to be concurrent with the other stations in the EDEN 

database (Conrads and Roehl, 2007).

For the development of the ground-elevation model 

(Jones and Price, 2007), the EDEN domain was divided into 

a large number of equal-sized 400-m2

 cells that in total are 

referred to as the “grid.” The grid includes information on the 

characteristics of each cell, such as centroid location, the area 

of the Everglades it represents, average elevation, and percentage of the vegetation type (slough, prairie, sawgrass, upland, 

exotic, and other). The large number of highly accurate 

elevation data allowed for further refinement of the groundelevation model. The geostatistical technique of kriging was 

selected for the EDEN ground-elevation model following 

extensive testing of multiple interpolation techniques. Kriging produced the lowest average error for validating elevation 

points and provides useful diagnostic surfaces. To account 

for variations within subregions of the EDEN area, individual 

geostatistical models were created for each water conservation area (WCA), the Everglades National Park (ENP), and 

portions of Big Cypress National Preserve (BCNP). These 

individual models were combined to create a single, 400-m2

-

resolution ground-elevation model for the entire EDEN 

domain (fig. 2).

A water-surface elevation model for the freshwater portion of the EDEN domain was developed in a GIS using the 

EDEN grid described above. The EDEN water-surface model 

interpolates measured daily water levels from 239 stations 

in the EDEN continuous monitoring network to ungaged

locations using radial basis functions (RBF) with multiquadric 

regression (Pearlstine and others, 2007; Palaseanu and Pearlstine, 2008). The model produces a continuous water surface 

for any day within the period of record in the EDEN database. 

An example of the water surface for two sample days is shown 

in figure 3. 

Often, data may be missing because of instrumentation 

or transmission problems for the 239-station network used to 

model the water surface of the freshwater portion of the Everglades. In addition, 25 stations currently (January 2009) do not 

have telemetry for real-time transmission of data. When data 

from a particular station are missing, the water-surface model 

does not use that station for generating the water-surface map 

for that day. Depending on the number of stations with missing data and the location, the quality of the water-surface maps 

can be diminished by missing data. To increase the accuracy of 

the daily water surface, water-level estimation equations were 

developed to fill missing data. For each station, at least three 

linear regression equations were developed to estimate missing data for the station. This report presents the development 

of the equations and summarizes their performance statistics.

Data-Collection Network

The EDEN database is composed of hourly water-level 

data from 256 gaging stations (239 stations in the freshwater 

portion of the Everglades) and includes marsh and river stations (appendix 1) and canal stations (appendix 2) operated 

by the BCNP, ENP, the South Florida Water Management 

District (SFWMD), and the U.S. Geological Survey (USGS). 

In this report, the names of the EDEN stations follow the 

naming convention used by EDEN (http://sofia.usgs.gov/eden/

explanation.php#stationname) and are generally similar to 

the names used by the agency that maintains the gage. The 

datasets with the estimated missing record are available on 

the EDEN Web page on the South Florida Information Access 

(SOFIA) Web site—http://sofia.usgs.gov/eden/index.php.

Estimation of Water-Level Data

The following procedure was used to develop estimation equations of water-level data for the 239 stations used to 

generate the surface-water maps: 

• A cross-correlation matrix of all the stations was generated using the daily values of the period of record of 

the EDEN database. For each station, the highest correlated stations were determined and used for input to the 

estimation equations.

• To minimize the inability to estimate data due to 

missing data from an input station, three equations 

were developed for each station using different input 

stations. For selected stations, a fourth equation was 

developed to further minimize the occurrence of missing estimations.

• Linear regression equations were generated by determining the slope and y-intercept for each station relative to the input stations. For each station, a priority 

was established for the order of the regression equations to be used to fill a data gap. The order that the 

equations will be used was based on performance statistics, visual inspection of equation predictions and measured data, and proximity of input and output stations.

• A Microsoft Access® database of the EDEN water-level 

data and estimation equations was developed to automate the filling of missing data. A log file is generated 

that documents which input station was used to fill 

missing water-level data for each station.

4 Estimation of Missing Water-Level Data for the Everglades Depth Estimation Network (EDEN)

The equations are in the form of y = mx+b, where y is the 

estimated value, m is the slope, x is the value from the input 

station, and b is the y-intercept. The equations were developed 

using 8 years of daily data and can be used to estimate either 

daily or hourly values. The EDEN water-surface elevation 

model uses daily median values to minimize the influence of 

outliers in the real-time data. 

The estimation of missing data is computed after the data 

is retrieved from NWIS and prior to pre-processing the data to 

generate daily water-level surfaces. The water-level data for a 

majority of stations in the National Water Information System (NWIS) are stored to North American Vertical Datum of 

1988 (NAVD 1988). For the stations with water levels stored 

to National Geodetic Vertical Datum of 1929 (NGVD 1929), 

the data preprocessing program converts the water-level data 

to NAVD 1988. The estimation equations use the datum used 

in the retrieval from NWIS, and the datums of the stations are 

listed in appendixes 1 and 2.

The 726 water-level estimation equations are presented in 

appendix 3. The stations are listed in numerical and alphabetical order. For each station, the three or four estimation 

equations are listed (Predictors—P1, P2, P3, and P4) with 

the values for the slope and y-intercept. Statistical measures 

of prediction accuracy for the estimation equations also are 

listed. The goodness-of-fit statistics presented in appendix 3 

for the equations are the Pearson correlation coefficient (R), 

coefficient of determination (R2

), mean error (ME), root mean 

square error (RMSE), standard error, relative bias (ME divided 

by the average measured value, in percent), percent model 

error (PME, computed as the RMSE divided by the range of 

the measured data), and Nash-Sutcliffe efficiency index. The 

order of the estimation equations generally was based on the 

overall goodness-of-fit represented by R2

 and RMSE. The 

location of the station and input stations (“predictors”) also are 

listed in appendix 3.

Each statistic measures a different aspect of the accuracy 

of the prediction equations. Estimation accuracy commonly is 

reported in terms of R2

 and is interpreted as the goodness-of-fit 

of an equation or model. A second interpretation may answer 

the question, “How much information does one variable or a 

group of variables provide about the behavior of another variable?” In the first context, an R2 = 0.6 might be disappointing, 

whereas in the latter, it is merely an accounting of how much 

information is shared by the variables being used. 

The standard error is the measure of the scatter of 

the actual observations about the regression line and is the 

standard deviation of the error of the predicted values in the 

regression. The standard error can be used to compute confidence intervals for the predictions. The relative bias is the 

ratio of the mean error to the average measured values.

The ME and RMSE statistics provide a measure of the 

prediction accuracy of the estimation equations. The ME is a 

measure of the bias of model predictions—whether the model 

over- or underpredicts the measured data. The ME is presented 

as the adjustment of the estimated values to equal the measured values; therefore, positive and negative MEs indicate an 

over- or underprediction bias by the model, respectively. MEs 

near zero may be misleading because negative and positive 

discrepancies in the simulations can cancel each other. RMSEs 

address the limitations of ME by computing the magnitude, 

rather than the direction (sign) of the discrepancies. The units 

of the ME and RMSE statistics are the same as the variable 

simulated by the model. Some find the bias of the model, or 

ME, easier to interpret when presented in relative terms. The 

relative bias is computed by dividing the ME by the mean of 

the measured values. 

The accuracy of the models, as given by RMSE, should 

be evaluated with respect to the range of the output variable. 

A model may have a low RMSE, but if the range of the output 

variable is small, the model may only be accurate for a limited 

range of conditions and the model error may be a relatively 

large percentage of the model response. Likewise, a model 

may have a large RMSE, but if the range of the output variable 

is large, the model error may be a relatively small percentage 

of the total model response. The PME is computed by dividing 

the RMSE by the range of the measured data.

To address the limitation of R2

, Nash and Sutcliffe (1970) 

developed an efficiency index to evaluate the goodness-of-fit 

of hydrologic models. The Nash-Sutcliffe efficiency index 

can range from –∞ to 1. An efficiency of 1 corresponds to a 

perfect match of simulated streamflow to the observed data. 

An efficiency of 0 indicates that the model predictions are as 

accurate as the mean of the observed data used to develop the 

model, whereas an efficiency index less than 0 occurs when 

the observed mean is a better predictor than the model. In 

summary, models with an efficiency index from 0 to 1 provide 

a better estimate than the mean of the observed data, and the 

higher the value, the better the estimates. Models with an 

index of 1 match the observed data perfectly, and for models 

with an index of less than 1, the mean of the observed data 

provides a better estimate. McCuen and others (2006) noted 

that only subjective evaluations of the efficiency index was 

possible and that the index is influenced by sample size, model 

bias, timing errors, and outliers. 

The following is an example of how to use appendix 3. 

Find the station of interest, for example S146_H, a marsh 

structure in Water Conservation Area 2A (appendix 1). The 

three input stations, or predictors, are S144_H, S145_H, and 

S11A_H and are listed as P1, P2, and P3, respectively. Make 

sure that the data for the predictor stations are for the datum 

used for the gage (appendixes 1 and 2). The water-level 

estimation will be for the datum used for the gage. The three 

estimation equations are:

P1: Yestimated = 1.02(X S144_H) –0.58,

P2: Yestimated = 0.99(X S145_H) –0.37, and

P3: Yestimated = 1.02(X S11A_H) –2.34.

The Yestimated station is S146_H, and X is the input (predictor) 

station. If the data for S146_H are missing, the first predictor 

station, S144_H, is used to estimate the data. In the event that 

the data for S144_H also are missing, then S145_H is used 

as the input station (P2). In the event that the data for both 
Estimation of Water-Level Data 5

S144_H and S145_H are missing, then the data for S11A_H 

are used as the input station (P3). As stated earlier, in some 

instances a fourth station is necessary when the first three 

input stations are missing data for the same period of time.

The R2s for the three estimation equations are 0.99, 

0.98, and 0.95, respectively, and the MEs are 0.04, 0.03, and 

0.04 foot (ft), respectively. The RMSE for the equations range 

from 0.16 to 0.25 ft, and the relative biases for the three equations are 0.4, 0.3, and 0.4 percent, respectively. The NashSutcliffe efficiency index was 0.97 for P1 and P2 and was 

0.93 for P3. Overall, the percent model error for the predictor 

equations is less than 5 percent. All three predictor stations 

are located in Water Conservation Area 2A. The measured 

and estimated water levels for station S146_H are shown in 

figure 4.

The majority of the water-level estimation equations provide good estimates for missing values. Figure 5A shows the 

sorted histogram of the frequency and cumulative percents of 

the R2s for the 239 first predictor estimation equations. Ninetyeight percent of the equations (234) have R2

s greater than 

0.70, and 2 percent (5 equations) have R2s less than 0.70. The 

frequency and cumulative percentages for all 726 equations 

are shown in figure 5B. More than 60 percent of the equations

Summary and Discussion

The Everglades Depth Estimation Network (EDEN) is 

an integrated network of real-time water-level gaging stations, 

ground-elevation models, and water-surface elevation models. 

The network provides scientists, engineers, and water-resource 

managers with current (2000–2009) water-depth information 

for the entire freshwater portion of the greater Everglades. 

A spatially-continuous interpolated water surface across the 

greater Everglades is generated from daily median water-level 

values. Missing or erroneous data diminish the quality of the 

modeled water surfaces. To increase the accuracy of the daily 

water-surface model, an application was developed to estimate 

water levels to fill data gaps. Missing data were estimated by 

developing linear regression equations for each site. To minimize the inability to estimate data due to missing data from an 

input site, three or four regression equations were developed 

for each site using different input sites. For each site, an order 

was established for the regression equation to be used to fill a 

data gap. The 726 equations were incorporated into a database 

application that automatically estimates missing records. The 

performance statistics computed for each equation provides 

documentation of the goodness-of-fit of the equations. In 

addition, although the majority of the equations provide 

satisfactory estimations of water levels, the performance 

statistic provides a prioritization for identifying stations where 

improved equations are needed to provide more satisfactory 

water-level estimates.
