преломление () изменение направления сейсмического луча при прохождении им сред с различными скоростями распространения в них волн; 2) образование преломлённых головных, рефрагированных волн, распространяющихся в высокоскоростной среде параллельно границам раздела)
The process by which the direction of a wave is changed when moving into shallow water at an angle to the bathymetric contours. The crest of the wave advancing in shallower water moves more slowly than the crest still advancing in deeper water, causing the wave crest to bend toward alignment with the underwater contours.
the tendency for waves to become more parallel to the coastline as they approach it. Caused by the slowing of waves at their base as they enter shallower water.
