Question

Longshore Drift Assignment 1). Describe in words or a diagram, your understanding of the process of wave refraction. 2) In a similar fashion, describe how the process of wave refraction can affect the sand along a shoreline. 3) In Figure a below, why are the wave crests curved? Is A or B the direction of the longshore current? In Figure b below, what artificial structures are along the beach? Is A or B the direction of the longshore current? In Figure c below, you see Cape Cod. What are the numbered natural structures called? Using the compass tell me what directions the longshore currents are flowing at: Location 1: — Location 2: — Location 3: _ Boss HIZITETE BRENDA ALAR HP WN RE 2 RI

Answer 1

Answer - 1)

Wave refraction is defined as bending of waves. And bending of waves takes place when waves move over different depth. And because of this bending waves moves parallel to the shore

Wave refraction helps in increasing or decreasing of wave height. It also helps in maintaining the wave strength.
