    141141fixstr1_2109a: The input flow rate was 12 L/s and the total experiment time was 21 minutes. The UVP was turned on as the gravity current entered the inlet box. The ADV was turned on 2 minutes after the UVP saw the flow. Two sets of siphon samples were collected three minutes after the current hit the end of the tank. Sampling was done every 10 minutes: Siphon Set !#1 (4:30 to 5:30) and Siphon Set !#2 (14:30 to 15:30). The flow was too thick and the velocity was about 18 cm/s. It was speculated that the flow rate should be decreased. Siphon samples showed a density decrease in depth, going from the bottom to the top, and also a decrease over time.

     143fixstr1_2109b: Since the flow was fast and thick, the flow rate was lowered from 10 L/s (t = 0 to 6 ) to 8 L/s (t = 8 to 13) to 6 L/s (t = 15 to 30). 3 sets of siphon samples were collected for the 3 flow rates at 3 different times (4:55 to 5:55, 12:02 to 13:02, and 19:26 to 20:26). The experiment lasted for 21 minutes.
