class opendrift.models.sedimentdrift.SedimentElement(**kwargs)

Bases: opendrift.models.oceandrift.Lagrangian3DArray

Extending LagrangianArray for elements moving in 3 dimensions The Particle may be buoyant and/or subject to vertical mixing buoyant bahaviour is described by terminal velocity

Initialises a LagrangianArray with given properties.

Args:

Keyword arguments (kwargs) with names corresponding to the OrderedDict ‘variables’ of the class, and corresponding values. The values must be ndarrays of equal length, or scalars. All (or none) variables must be given, unless a default value is specified in the OrderedDict ‘variables’ An empty object may be created by giving no input.

class opendrift.models.sedimentdrift.SedimentDrift(*args, **kwargs)

Bases: opendrift.models.oceandrift.OceanDrift

Model for sediment drift, under development

Constructor of SedimentDrift module

ElementType

Any trajectory model implementation must define an ElementType.

required_variables

Any trajectory model implementation must list needed variables.

update()

Update positions and properties of sediment particles.

bottom_interaction(seafloor_depth)

Sub method of vertical_mixing, determines settling

resuspension()

Resuspending elements if current speed > .5 m/s
