Statement: Autogenic Storage and Release
Abstract: This movie shows an experimental delta built into standing water (constant depth of 3 cm). All external controls are constant (sediment flux, water discharge, base level changes). Fluvial system alternates between sediment release (channelization) and sediment storage (sheet flow).
Fluvial system alternates between sediment storage and release due to autogenic slope fluctuations on the deltaic surface. Shoreline progradation rates increase during release events and slow during sediment storage. This process is entirely autogenic (internally generated, i.e., no external controls were changing to induce this process).
