Model help:Plume

Plume

Plume models a hypopycnal sediment plume draining from a river mouth into a lake or the ocean

Model introduction

Plume simulates the sediment transport and deposition of single-grain size sediment from a river mouth entering into a marine basin by creating a turbulent jet. The model calculates a steady-state hypopycnal plume as a result of river water and sediment discharge based on simplified advection-diffusion equations. The model allows for plume deflection due to systematic coastal currents or Coriolis force

Model parameters

Parameter	Description	Unit
First parameter	Average mass-concentration of suspended sediment	[kg/m3]
u₀	Flow velocity at the river mouth	[m/s]
b₀	Width at the river mouth	[m]
d₀	Depth at the river mouth	[m]
d₀	Angle of river mouth measured with respect to the coast normal	[degrees]
Lat	Latitude of river mouth location, affect the Coriolis Force	[degrees]
W	Width of the ocean/fjord, affects the spreading of the plume	[m]
L	Length of the ocean/fjord or lake	[m]

Parameter	Description	Unit
Rho-sediment	Saturated bulk density of sediment	[kg/m³]
Lambda	Removal rate of suspended sediment	{ 1/day]
