  1. EQUILIBRIUM BEACH PROFILE A is the profile scale factor, much more detail in later chapters

  2. EQUILIBRIUM BEACH PROFILE Steeper than equilibrium Excess sediment on profile. Sediment needs to be transported offshore to re-attain equilibrium

  3. EQUILIBRIUM BEACH PROFILE Flatter than equilibrium Shortage of sediment on profile. Sediment needs to be transported onshore to re-attain equilibrium

  4. SHORLINE OF SUBMERGENCE Energy eventually distributed over a wider surf zone and planform irregularities get smoothed out. Coastal Processes with Engineering Applications (Dean and Dalrymple)

  5. SPITS Coastal Processes with Engineering Applications (Dean and Dalrymple)

  6. SPITS HOME FOR SALE

  7. SPITS – BAYMOUTH BARRIER http://collections.ic.gc.ca/geoscience/images/detail/A94S0061.jpg

  8. TOMBOLO Don’t stare too hard

  9. INLETS Often see build up of sediment on updrift side of inlet, especially if it is jettied. Can get overlapping of downdrift barrier especially when no jetties exist. Coastal Processes with Engineering Applications (Dean and Dalrymple)
