I am longing to dwell by the sea,
And dip in the surf every day,
And--height of subaqueous glee--
With the sharks and the porpoises play.

There is a magic made by melody:
A spell of rest, and quiet breath, and cool
Heart, that sinks through fading colors deep
To the subaqueous stillness of the sea,
And floats forever in a moon-green pool,
Held in the arms of rhythm and of sleep.
"I Am In Need Of Music" by Elizabeth Bishop

Therefore, ˜P also changes nearly scale-invariantly with u∗ , such that cv is nearly constant with u∗ also for sediment transport in the subaqueous regime.
Analytical model for flux saturation in sediment transport
Bagnold [31, 35] was the first who proposed that this frictional force is approximately proportional to the normal force which the transport layer applies on the sediment bed (Coulomb friction law), independently of whether the transport regime is subaqueous or aeolian.
Analytical model for flux saturation in sediment transport
In this Section, we use the results presented in last Section in order to derive a closed expression for the saturation length as a function of the attributes of sediment and flow, both for aeolian and subaqueous regimes.

In Sections III C and III D we show how the saturation length equation can be applied to compute Ls in the aeolian and subaqueous regimes, respectively.
Analytical model for flux saturation in sediment transport

Analytical model for flux saturation in sediment transport
Indeed, values within the range between µ/ca = 0.3 and µ/ca = 0.5 — and thus consistent with the value of µ estimated above — have been reported from measurements of particle tra jectories in the subaqueous sediment transport [42–44].

Subaqueous regime of transport — The change in the transport-flow feedback due to the saturation of the flux is negligible in the subaqueous regime, since in this regime cU ≈ 0 and thus K ≈ 1.
