NodeMaxInflowReservoir Class

A functionality to node to limit total inflow from surface. Total inflow in m3/s, from multiple sources.

The class handles two types of inflow, surface inflow and catchment runoff inflow. The procedure models that the catchment runoff inflow "runs through" the surface model before entering the node.

Syntax

Copy

public class NodeMaxInflowReservoir : ISourcePoint, 
	IComponentSourcePoint

The NodeMaxInflowReservoir type exposes the following members.

Properties

	Name	Description
	ActualInflow	Actual total inflow to node for current time step
	ActualSurfaceInflow	Actual surface inflow for current time step, different from what was set in AddSurfaceContribution when max inflow limit is in effect
	ComponentMassInReservoir	Amount of component (mass) retained in reservoir
	WaterVolumeInReservoir	Amount of water retained in reservoir

Methods

	Name	Description
	AddSourceContribution(Double)	Add a contribution to the source.
	AddSourceContribution(Int32, Double)	Add a mass contribution to the AD source for the specified component.
	AddSourceContribution(Int32, Double, Double)	Add a concentration contribution to the source for the specified component.
	AddSourcePerAreaContribution	Add a contribution per area unit to the source.
	AddSourcePerLengthContribution	Add a contribution per length to the source.
	AddSurfaceContribution(Double)	Add a surface inflow contribution Note that only one surface connection is supported, so this should not be called twice (the second call will override the first)
	AddSurfaceContribution(Double, Double)	Add a surface inflow contribution as an implicit source Note that only one surface connection is supported, so this should not be called twice (the second call will override the first)
	EmptyReservoir	Empty reservoir
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OutflowConcentration	The outflow concentration, i.e. concentration of flow out of the node.
	SetSurfaceConcentration	Set concentration of component for surface inflow. Only used if surface inflow is positive. When negative, water flows out with concentration in node.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

The following rules apply: - Water from surface has "higher" priority than water from catchment i.e. water from surface enters the node first, and then water from catchment if there is room within the max-inflow limit - Only one surface connection is supported, i.e. the surface methods AddSurfaceContribution(Double) and the AD counterparts can only be called once per timestep. - Water from surface, when limited, is not added to reservoir, assuming surface model has its own reservoir. So the user must keep track of what was actually added, by quering ActualSurfaceInflow - When inflow is limited, catchment inflow is retained in a reservoir. - Water from catchment and reservoir are mixing immediately - When coupled to a surface model, you can query the properties of the reservoir and empty it, EmptyReservoir, in order to transfer reservoir content to an external surface model. - If surface inflow is negative (outflow from node), other inflows can not enter the node and hence all catchment inflow is retained in the reservoir. - AD contributions from surface must be concentrations.
