    139139Experiment name: fixstr_2109a, b. File names: fixtr1_2109a, fixstr1_2109b. Location: Position X1 (75% down straight section, 58 cm upstream from the end of the straight section). Density excess 10.3 kg/m^3^.

    141 fixstr1_2109a: The input flow rate was 12 L/s. 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.
