Step discharge changes from Q1 => Q2 => Q1 July25 (S1 in paper): Q1 = 39.1 L/s, Q2 = 111.7 L/s July27 (S2 in paper): Q1 = 39.1 L/s, Q2 = 81.4 L/s Aug1: Q1 = 39.1 L/s, Q2 = 63.3 L/s Aug5 (S3 in paper): Q1 = 39.1 L/s, Q2 = 81.4 L/s Aug17: Q1 = 39.1 L/s, Q2 = 111.7 L/s "DoublePassRuns" - Experiments with sonar passing alternately at 30 cm and 60 cm (flume width is 90 cm). Step discharge changes from Q1 => Q2 => Q1 Aug8 (D1 in paper): Q1 = 63.3 L/s, Q2 = 81.4 L/s Aug10 (D2 in paper): Q1 = 63.3 L/s, Q2 = 111.7 L/s "FloodRuns" - Experiments with sonar in flume centerline. Discharge increases and decreases gradually according to a triangular floodwave. See documentation files for more info. Aug11 ("slow" wave in paper): Medium duration floodwave Aug12: Rapid floodwave Aug16 ("fast" wave in paper): Rapid floodwave %%%%%%%%%%%%%%%%%%%%% DATA FORMATS Data for SinglePassRuns, DoublePassRuns, and FloodRuns are in Octave/Matlab text files. "Z" files (Z_1 and Z_2 for DoublePassRuns) contain matrices of sonar pass elevations. Rows are individual passes, with 1 cm intervals from 500 cm to 1300 cm from the beginning of the flume. Successive timesteps are in successive rows. Corresponding times (from beginning of run) are in the file "sonar_t". Elevations are in cm (relative to top of flume, so negative values are below the top of the flume). "massa_Z" (massa_Z_1 and massa_Z_2 for DoublePassRuns) contain matrices of water surface elevations. Rows are individual passes, with 1 cm intervals from 480 to 1280 cm from the beginning of the flume, and successive timesteps in successive rows. "transition_times" contains information about when discharge was changed from Q1=>Q2 (Q2_t) and from Q2=>Q1 (Q1_t), except for FloodRuns, where beginning, peak, and ending times for triangular floodwaves are given instead. Erroneous spikes in the bed and water surface elevations have been removed (and interpolated over), otherwise no other processing has been performed on the data. DAQ Scripting files "SAFL_TiltingBed_EightPasses_5to13" does 8 parallel passes with the sonar "SAFL_TiltingBed_SinglePassAndReturn_5to13" does a single pass, back and forth, with the sonar
