- 6.3: Water Motions Due to Waves
- The aspect of surface gravity waves that is relevant to sediment movement lies largely in the back-and-forth movement of the water at the bottom: are those oscillatory currents strong enough to entrain bottom sediment? To get at the nature of bottom water motions under oscillatory waves, it is best to start with small-amplitude wave theory.
