Today the final set of tests for rig 1 and 2 were completed (DR0 - 20 hours), and the instruments logged for the final time.
Half way through the test the vectrinos were buried, and we jumped into the freezing flume (for the last time-Yay!). We rotated the clamps up, rising the entire rig. All the equipment actually worked, apart from the final 3 hour run, our ABS would not respond...obviously something had to fail. On a positive note, the profiles came out looking pretty good (fig.1). When comparing test SB0_14 to DR0_14 (fig.3), which is the final profile of the tests, they should be identical (in theory) due to it being the same test being repeated. In general the profile is very similar, and only significantly differs ~235 m where SB0 has bedforms and DR0 has an inner sand bar.
So, apart from that me and Emily are done and dusted for our part of the experiment. We were joined by two more people from Plymouth Uni, Jak and Aaron, to help dismantle and pack everything from rig 1 and 2, ready to be shipped back to the UK.

Fig.2 - Cross-shore profile of test DR01 to 14. An increase in erosion is occurring on the beach-face, moving the sediment offshore, increasing the size of the sand bar. |
