Surf - waves that have reached the coast, grow in height, and break Wave height/wave length. Wave Motion with Depth (Figure 7-3a) (Figure 7-6b) Slower speeds than surface waves because the density difference between water masses is less than between air and water. Also, waves do not typically reach the beach perfectly parallel to the shoreline. Rather, they arrive at a slight angle, called the angle of wave approach. When a wave reaches a beach or coastline, it releases a burst of energy that generates a current, which runs parallel to the shoreline. This type of current is called a longshore current. -The natural circular motion within the wave The result is amplification of the wave size which can lead to flooding. Formula on pg.
