Sea level is rising

Flume re-filled, this time with an increase of 0.1 m, making the sea level now 4.8 m. The sand bar carries on migrating seawards, until the last run (SB3_6, in green), the bar starts to migrate landwards. Erosion occurring on the beach face is larger between the first 3 runs, but this decreases once the 60 minute wave sets run and the beach becomes stable.

Sea level = 4.8 m
Wave height = 0.8 m
Wave period = 6.0 s
