4.4. OTHER MODEL STUDY CONSIDERATIONS
163
might specify that seiching within particular mooring regions of the harbor
must not surpass a certain level. Therefore, it is imperative that data be
collected at these locations, and enough gages are used to assure needed
information is captured. If the model is being verified with prototype data,
similar model data must be collected at the same locations as collected at
the prototype site. Currents can be measured at specific locations thought
to be trouble areas, or the general circulation patterns can be captured using dye injection methods. Finally, various visualization techniques can be
employed to document overall model response (overhead photographs), dynamic events that are difficult to capture with insitu instrumentation (highspeed filming), or processes that develop over time (slow-motion filming of
thermal plume spreading).
Most established laboratories that perform physical modeling have their
own particular methods for conducting model studies. Some of the techniques have evolved over time as a result of experience, while other techniques have been acquired from other laboratories doing similar types of
modeling. Experience certainly is an important aspect of physical modeling,
just as it is for all other engineering endeavors, and the beginning modeler
will find most engineers who are experienced in the physical modeling are
more than happy to share their accumulated knowledge!
