Appendix B
Physical Modeling of North

Beach and Jetty
Introduction
Appendix B contains supplemental figures and tables to augment Chapter 5
of Volume I of this report. Figures include photographs taken during studies with
coal tracer and dye, figures showing wave heights at each of the wave gauge
locations, and plots showing differences in wave heights between structural
alternatives for the same generated storm and water level. Tables summarize
wave heights and wave periods calculated at each of the wave gauges, and
velocities calculated at each of the velocimeters. Where available, figures of coal
tracer studies and dye studies include a label indicating time from start of
experiment. Times are given in model scale and should be multiplied by 8.66 to
convert to prototype scale.
Figures B1 through B55 document results obtained with storms from the
west-northwest. Figures B1 through B14 contain photographs taken during
experiments with coal tracer, and Figures B15 through B46 show photographs
taken during experiments with dye. Figures B47 through B55 show differences in
calculated wave heights at each wave gauge with Alt 2A compared to wave
heights calculated with Alt 1. The alternatives are described in Chapter 1 of
Volume 1.
Figures B56 through B91 document results obtained with storms from the
southwest. Figures B56 through B64 contain photographs taken during
experiments with Alt 1 and Figures B65 through B73 contain photographs taken
during experiments with Alt 2A. Differences in calculated wave heights at each
wave gauge with Alt 2A compared to Alt 1 are shown in Figures B74 through
B82; differences in calculated wave heights at each wave gauge with Alt 3B
compared to Alt 1 are shown in Figures B83 through B91.
Figures B92 through B113 document results obtained during experiments
with Alt 2A and the GENEralized model for SImulating Shoreline change
