LIDLayerSurface Class

Surface LID layer.

To enable surface routing, both the ManningM and the Slope must be set.

Properties

	Name	Description
	Depth	Depth of surface storage [m]. State variable
	DepthOld	Depth of surface storage in last time step[m].
	Evap	Evaporation rate from surface [m/s]
	Infil	Infiltration rate from surface to lower layer [m/s]
	ManningM	Manning´s M for overland flow over the surface.
	Outflow	Outflow rate (overflow/runoff) from surface [m/s]
	Slope	Slope of surface (fraction).
	StorageHeight	Height of surface storage [m]. Above this depth, overflow occurs.
	SurfaceAlpha	Helper variable, containing Copy ManningM*sqrt(Slope) . If zero, routing is disabled.
	UsesRouting	Bool indicating if routing is enabled (SurfaceAlpha is greater than zero).
	VegetationFraction	The fraction of the surface storage that is filled with vegetation. Default value: 0. Unit: [m].
	Volume	Volume of water per area [m] contained on surface

Methods

	Name	Description
	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 the default hash function. (Inherited from Object.)
	getSurfaceOutflowRate	Computes outflow rate [m/s], based on Mannings equation. If routing is disabled, this returns zero.
	getSurfaceOverflow	Finds surface overflow rate [m/s], assuming all water above StorageHeight is diverted. If routing is enabled, this returns zero.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetVolume	Volume of water per area [m] contained on surface for a given depth
	Limit	Limit state variables to allowed range, cannot be negative
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Prepare	Prepare surface
	PrepareSurfaceRouting	Whenever ManningM or Slope is updated, this needs to be called.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Validate	Validate surface parameters
