Let the flume see the waves!

Day 7 in the Large Water Flume...
Beach drained, profile revealed, wonky rig! Not ideal... Everyone in the flume!
Unsurprisingly the rig was quite heavy, but rig 1 is now level with the horizontal bar and we're ready for waves.

Again, another successful day, apart from the vectrinos of course... same story different day, maybe they won't timeout tomorrow! The 3D scanner is showing the sand bar migrating seawards with the inner bar following behind. Completed 1x2 hour and 1x3 hour run of SB0. The instruments don't seem to be submerged in the seabed so no need to drain the flume again tonight. Everyone's happy, so all is good in the Large Water Flume!

Sea level = 4.5 m
Wave height = 0.8 m
Wave period = 6.0 s

Ozzy, Paul and Chris making themselves look busy on the trolley!

3D Sonar Scan screenshot of the profile at 228.79 m with a 4.5 m radius. Top right image is a birds eye view of the seabed (the top being landwards, bottom being seawards). Red represents an elevation in sediment and green a decrease. Bottom left is a side on view of the cross-shore profile, you can see the crest of the bar on the left, before the shadowing of data appears and on the right the inner bar is starting to emerge. Bottom right image is the final 3D image - it has been rotated so that it is looking at the beach profile side on, with the right side being landwards and left being seawards. This angle shows a clearer view of the inner sand bar (on the right) the trough (in the middle, green) and the outer sandbar (on the left).
