VARIATION OF PARAMETERS OF INERTIAL WAVES IN THE COASTAL AND SHALLOW WATERS AREAS OF THE SEA

A. L. Bondarenko and V. A. Shchev'ev

Results of in situ research on inertial waves in the coastal sea zone and shallow waters are presented. Inertial waves are considered to form and exist only in deep water far from the coast. Here it is first shown that these waves are also observed near the coasts and in shallow waters; however, they are prone to changes, including their form. With the growing effect of shallow waters on a wave, the energy maximum in the flow spectrum in the inertial period decreases and finally disappears, with energy maximums appearing in the periods that exceed the inertial period. The amplitude of flow velocity oscillations decreases, too, but occasionally, due to resonance excitation, flow velocities may attain very high values, up to 1.0—1.5 m/s.
