pywatershed.PassThroughFlowNode

class pywatershed.PassThroughFlowNode(control)

A FlowNode instance that gives what it takes and dosent store.

See FlowGraph for a worked example using PassThroughFlowNode.

__init__(control)

Initialize a PassThroughFlowNode.

Parameters:

control (Control) – A control object.

Methods

__init__(control)	Initialize a PassThroughFlowNode.
advance()	Advance this FlowNode to the next timestep.
calculate_subtimestep(isubstep, ...)	Calculate the subtimestep.
finalize_timestep()	Finalize the current timestep at this FlowNode.
prepare_timestep()	Prepare the subtimestep for subtimestep calculations.

Attributes

outflow	The average outflow of the FlowNode over the current timestep.
outflow_substep	The outflow of the FlowNode over the sub-timestep.
sink_source	The sink or source amount of the FlowNode at the current subtimestep.
storage	The storage of the FlowNode at the current subtimestep.
storage_change	The storage change of the FlowNode at the current subtimestep.

advance()

Advance this FlowNode to the next timestep.

calculate_subtimestep(isubstep, inflow_upstream, inflow_lateral)

Calculate the subtimestep.

Parameters:

• isubstep (int) – Zero-based integer indicating the index of the current substep.

• inflow_upstream (float) – The in-channel flows to this FlowNode on the current substep.

• inflow_lateral (float) – The later flows to this FlowNode on the current substep.

finalize_timestep()

Finalize the current timestep at this FlowNode.
