The following table displays the attribute table field definitions from the CERI table as created in Step 2a.

Fields Created via Step 2a
Column Alias Column Definition Column Alias Column Definition
Trans_ID Transect ID from Transect Feature Class PW Protective Width
H_Unit Horizontal Unit (Feet or Meters) PE Protective Elevation
V_Unit Vertical Unit (Feet or Meters) DE Dune Elevation
MHW_Elev Mean High Water Elevation Mean_Slope Mean Slope, from the MHW to the Dune Toe
MHW_Rng Mean High Water Range MHW_Slope MHW Slope, within 0.5 meters landward and seaward of the MHW point
TO_Elev Dune Toe Elevation FD_Width Frontal Dune Width, from the back trough to the dune toe
TO_Rng Dune Toe Range Beach_Width Beach Width, from the back trough to the MHW
FD_Elev Frontal Dune Elevation BarCount Number of bars detected
FD_Rng Frontal Dune Range BarDistX Bar Distance, with X being the bar number
BT_Elev Back Trough Elevation BarDepX Bar Depth, with the X being the bar number
BT_Rng Back Trough Range AveWavelength Average Wavelength from depth of closure*
HE_Elev Highest Elevation Value Concave Concave up or down to depth of closure*
HE_Rng Highest Elevation Range Curve_h When fitting a second degree polynomial from shoreline to depth of closure, height of curve*
LL_Elev Landward Limit Elevation Curve_b When fitting a second degree polynomial from shoreline to depth of closure, distance from endpoint to endpoint*
LL_Rng Landward Limit Range NearshoreSlope Slope of second degree polynomial from shoreline to depth of closure*

*see Sylvester et al. (2023) for more information on nearshore curvature calculations.


The following table displays the attribute table field definitions from the CERI table as created in Step 3.

Fields Created via Step 3**
Column Alias Column Definition Column Alias Column Definition
H0 Wave height from lookup table a CERI Factor A value
L0 Wavelength from lookup table b CERI Factor B value
R2 The calculated 2% wave runup exceedance value (Stockdon et al. 2006) d CERI Factor C value
EWL Extreme Water Level d CERI Factor D value
MR Maximum Runup e CERI Factor E value
CERI The CERI value, the summation of Factors A-E.

**all fields generated in Step 3 include an appended _wXeY where X is the wave return period and Y is the extreme water level return period (e.g. H0_w10e10)
