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.

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 24.5 hrs and amplitudes of 6.125 mm.

TDB-14-1: 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 630 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 with periods of 98 hrs and amplitudes of 24.5 mm.

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-11-1: Fan-delta experiment performed in Tulane University Delta Basin. Experiment evolved under constant forcings of water (0.902 l/s), sediment (0.011 l/s), and sea-level rise rate 5 mm/hr). Experiment run time was 77.2 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.

Prograding delta built under a stationary lid to simulate the back-pressure of a backwater effect. Delta built with:

• Dyed water
• Plastic, colored sediments

This delta was built in a "desktop experiment" as part of the CSDMS-SEN 2016 meeting.
