3 Non-cohesive deltas undergoing pure aggradation with different water and sediment feeds. Video of laboratory experiments documenting evolution of 3 channelized deltas each experiencing their own constant relative
subsidence rate and water and sediment feed rates. Video is presented at 720 times the actual experimental run-time. Video includes evolution of
deltas over an 8.6 hr window. Blue dye added to water aids identification of flow field. More details of experiment can be found in manuscript: Straub, K.M., and Esposito, C.R., 2013, Influence of water and sediment supply on the stratigraphic record of
alluvial fans and deltas: Process controls on stratigraphic completeness, Journal of Geophysical Research - Earth Surface, v. 118,

Evolution of Synthetic Stratigraphy Generated by
a Non-cohesive delta undergoing pure aggradation Video of laboratory experiments documenting evolution of channelized delta experiencing relative subsidence at a constant rate.
Evolution of synthetic stratigraphy generated from topographic scans of delta topography clipped for erosion. Each frame of movie represents
evolution of stratigraphy over 2 minute window. Stratigraphy from proximal laser location of TDB-11-1 experiment. Video is presented at 720 times
the actual experimental run-time. Video includes evolution of delta. More details of experiment can be found in manuscript: Straub, K.M., and Esposito, C.R., 2013, Influence of water and sediment supply on the stratigraphic record of
alluvial fans and deltas: Process controls on stratigraphic completeness, Journal of Geophysical Research - Earth Surface, v. 118,

Non-cohesive delta undergoing pure aggradation Video of laboratory experiments documenting evolution of channelized delta experiencing relative subsidence at a constant rate. Digital
video was collected from camera at an approximately 45 degree from vertical which was then post-processed to remove camera distortion to yield a close to
synoptic representation of the experimental basin. Video is presented at 360 times the actual experimental run-time. Video includes evolution of delta
between run hours 70-79. Blue dye added to water aids identification of flow field. More details of experiment can be found in

autogenic timescales in channelized sedimentary deposits, Geology, v. 39(9), p 811-814, DOI: 10.1130/G32068.1.
