Ideal case of a stable null point (Walton 1972)
(4) Kana (1978) measured the vertical suspended sediment concentration at locations across the surf
zone, and longshore current velocity at a mid-surf position. His measurements indicated that, for spilling
waves, sediment concentration rapidly increased inside the breakpoint, then remained relatively constant
under the bore as it propagated towards the beach. For plunging waves, sediment concentration peaked
