This appendix presents plots and tables of normalized spectral energy density

collocated Coastal Inlets Imaging system (CIIS) and Accoustic Doppler

Velocimeter (ADV) measurements for Structure 1, Experiments 4 through 6. *S*(*f*)

is normalized by the maximum value of the variance spectrum for a given

experiment and sensor. Tick ("+") marks on wave direction curves represent

CIIS measurements that meet the coherence cutoff criterion discussed in

Chapter 5.

Plot and table titles include 6-digit strings that indicate structure (characters

1-2), experiment (characters 3-4), and gauge arrangement (characters 5-6). For

example, S1X4G1 represents Structure 1, Experiment 4, Gauge Arrangement 1.

The legend of each plot indicates ADV probe identification number and camera

identification number.

m /Hz for ADV and *I */Hz for CIIS . Normalized by maximum *S*( *f *).

θm( *f *)

Vector-mean wave direction as a function of frequency presented in units of deg

relative to model coordinate system

θm( *f *)C

Vector-mean wave direction as a function of frequency presented in units of deg

relative to model coordinate system following application of coherence cutoff

criteria. Values of not meeting the cutoff criterion are presented as NaN values

(i.e., not-a-number).
