Abstract

These experiments were conducted in St. Anthony Fall Laboratory (SAFL) Delta Basin. This is a fixed based basin (5 m wide x 5 m long x 0.5 m deep) that is fed sediment and water from an input source to create model deltas. Sea-level adjustment via relative sea-level rise is available in this facility and was used for these experiments along with a floating wave generator. This facility is able to collect data via an overhead DSLR camera (which made the time-lapse videos themselves) and a digital line scan camera capable of making digital elevation models with sub-millimeter accuracy.

Description

Delta experiments ran in Delta Basin-2 (DB2) with fluvial and wave forcing. Deltas experienced 2.5 mm/hr or 5 mm/hr of relative sea-level rise and a constant wave climate. Water and sediment discharge rates were varied between experiments to control the delta-top slope. ShallowFast: water discharge 0.1 Liter/second (L/s), sediment discharge 0.001 L/s, slope 0.008, relative sea level rise 5 mm/hr. ShallowSlow: water discharge 0.1 Liter/second (L/s), sediment discharge 0.001 L/s, slope 0.009, relative sea level rise 2.5 mm/hr. SteepFast: water discharge 0.1 Liter/second (L/s), sediment discharge 0.002 L/s, slope 0.017, relative sea level rise 5 mm/hr. SteepSlow: water discharge 0.05 Liter/second (L/s), sediment discharge 0.001 L/s, slope 0.014, relative sea level rise 2.5 mm/hr. The videos were made by stitching together thousands of pictures taken from a fixed camera above the basin. The camera is oriented so that each pixel is roughly 1mm by 1mm. The scans generate a elevation model where each pixel is approximately 1mm by 1mm.
