TDB_15_1, Tulane Delta Basin

TDB-15-1: Fan-delta experiment performed in Tulane University Delta Basin. Experiment evolved under constant forcings of water (0.17 l/s), sediment (0.00017 l/s), and long term sea-level rise rate (0.25 mm/hr). Experiment run time was 1170 hr. Experiment used a strongly cohesive sediment that had a wide grain size distribution with a median diameter of 65 microns. Superimposed on the long term sea-level rise were sea-level cycles. The experiment was split into 2 stages. The first stage had sea-level cycles with periods of 98 hrs and amplitudes of 3.06 mm.

TDB_13_1, Tulane Delta Basin

TDB-13-1: Fan-delta experiment performed in Tulane University Delta Basin. Experiment evolved under constant forcings of water (0.17 l/s), sediment (0.00017 l/s), and sea-level rise rate (0.25 mm/hr). Experiment run time was 1000 hr. Experiment was divided into 2 stages. The first stage used a weakly cohesive sediment while the second stage used a moderately cohesive sediment. Both sediment mixtures had wide grain size distributions with a median diameter of 65 microns.

TDB-12-1: Fan-delta experiment performed in Tulane University Delta Basin. Experiment evolved under constant forcings of water (0.17 l/s), sediment (0.00017 l/s), and sea-level rise rate 0.25 (mm/hr). Experiment run time was 1285 hr. Experiment used a strongly cohesive sediment that had a wide grain size distribution with a median diameter of 65 microns. Experiment performed to explore autogenic sediment transport and stratigraphy with topography monitored every 1 hour of run time.

TDB-10-2, Tulane Delta Basin

TDB-10-2: Fan-delta experiment performed in Tulane University Delta Basin. Experiment evolved under constant forcings of water (0.902 l/s), sediment (0.022 l/s), and sea-level rise rate 10 mm/hr). Experiment run time was 39.3 hr. Experiment used non-cohesive sediment that was 70% by volume well sorted quartz sand with a median diameter of 110 microns and 30% by volume crushed coal with a median diameter of 400 microns. Experiment performed to explore autogenic sediment transport and stratigraphy with topography monitored every 2 minutes of run time.

SAFL density current basin

Basin for fluvial sediment transport experiments, including density currents. Two slope breaks in the basin favor sediment deposition, with a maximum accomodation space of approximately 5 cm. The bed slope is adjustable. Pumps are used to supply inflow and to control the water level.

Data acquisition options include overheard photos and topographic scanning.

Size: 4.0 m x 1.0 m x 0.5 m (length, width, height)

Ensemble Distributions of Particle Motions

Data here was collected at the River Dynamics Laboratory at Arizona State University.  Measurements of particle motions were obtained using a manual tracking method within the program ImageJ.  The data include 1250 frames or 5 seconds of high-speed imagery, associated coordinates of particle motions, and derived measurements of particle motions (e.g. instantaneous velocities, particle accelerations, hop distances, and travel times).
