Appendix P
ADV and CIIS Measurement
Comparison: Structure 1
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

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).
