Sand is removed from the surf zone at a rate of 100 m3/day.

(a) In Case A, the waves approach the shoreline normally. Qualitatively sketch the planform variation with time.

(b) In Case B, the waves approach the shoreline such that along the straight shoreline the transport is 50 m3/day. Qualitatively sketch the beach planform variation with time.
