Role of Laboratory Experiments and Models in the Study of Sea Strait Processes

Part of the NATO ASI Series book series (ASIC, volume 318)


A brief review of fluid mechanical laboratory studies shows that many physical processes of flows in sea straits can be studied quantitatively, and that physical insight in the interpretation of field data has often been gained by means of very simple, but careful laboratory experiments. Multi-scale energetics have, for example, provided algorithms for computing mass and momentum exchanges in straits.

Laboratory models can provide fine spatial resolution and coupled physics for testing advanced numerical schemes. Studies of large scale geophysical flows must conform to Froude-Rossby similitude. Effects like surface tension, molecular friction, improper boundary conditions and noisy measurements must be evaluated before making comparisons with theory or field data.
