How do jetties protect harbor entrances?
  • The wintertime beach would look similar to the summertime beach.
  • rivers.local biological activity.coastal erosion.
  • Winter waves are short and high, whereas summer waves are long and shallower.
  • by inhibiting the deposition of sand in the harbor mouth
What would you do to both grow a large beach and protect a harbor mouth?
  • Place two jetties on either side of the harbor mouth, and build a breakwater upcurrent from the harbor mouth.
  • Small waves move sand up the beach face and create a wide, sandy beach.
  • Low rates of erosionHigh sediment loadHigh rates of depositionSmall wave energyA large-volume river
  • during summertime there is much more sand on the beach
built parallel to a shoreline-harbor

  • How long does it take berms to become narrow and rocky after summer has passed?
  • In the long term, what do beach drift and longshore current do?
  • Which of the following structures are types of coastal stabilization structures?
  • Which way would sediment move if NO beach drift existed?
built perpendicular to a coastline and are specifically designed to trap sand moving along the ocast in longshore transport-large blocks of rocky material (rip-rap)
  • Jetty
  • Breakwater
  • Hard Stabilization
  • Groin
one of the most destructive type-built parallel to shore-armors coastline and protects landward developments from ocean waves
  • What would you do to both grow a large beach and protect a harbor mouth?
  • How would a beach be affected if a wide berm were protected from erosion during winter months?
  • Seawall
  • How are winter beaches different from summer beaches?
built perpendicular to the shore and is usually constructed of rip-rap-usually built in closely spaced pairs and can be quite long, they can cause more pronounced upcoast depositon and downcoast erosion-protect harbor entrances from waves and only secondarily does it trap sand

Beaches tend to have a narrow berm and a prominent longshore bar.
  • In general, what do beaches look like at the end of summer?
  • Why are coastal stabilization structures built along coastlines?

  • Hard Stabilization
structures built to protect a coast from erosion or to prevent the movement of sand along a beach
