Profile Feature Extraction: CERI Attribute Table Definitions

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)
