Abstract
The planform of estuaries is often described with an ideal shape, which exponentially
converges in landward direction. We show how growing topographically forced nonmigratory (i.e., anchored) bars determine the large-scale estuary planform, which explains the deviations observed in the planform of natural estuaries filled with bars compared to the ideal planform. Experiments were conducted in a 20-m long, 3-m-wide tilting flume, the Metronome. From a narrow, converging channel a self-formed
estuary developed characterized by multiple channels, braided bars, a meandering ebb channel, and an ebb delta. Bars hardly migrated due to the alte... more
