Surface LID layer.

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

Properties
  NameDescription
Public propertyDepth
Depth of surface storage [m]. State variable
Public propertyDepthOld
Depth of surface storage in last time step[m].
Public propertyEvap
Evaporation rate from surface [m/s]
Public propertyInfil
Infiltration rate from surface to lower layer [m/s]
Public propertyManningM
Manning´s M for overland flow over the surface.
Public propertyOutflow
Outflow rate (overflow/runoff) from surface [m/s]
Public propertySlope
Slope of surface (fraction).
Public propertyStorageHeight
Height of surface storage [m]. Above this depth, overflow occurs.
Public propertySurfaceAlpha
Helper variable, containing
ManningM*sqrt(Slope)
. If zero, routing is disabled.
Public propertyUsesRouting
Bool indicating if routing is enabled (SurfaceAlpha is greater than zero).
Public propertyVegetationFraction
The fraction of the surface storage that is filled with vegetation.

Default value: 0. Unit: [m].

Public propertyVolume
Volume of water per area [m] contained on surface

Methods
  NameDescription
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodgetSurfaceOutflowRate
Computes outflow rate [m/s], based on Mannings equation.

If routing is disabled, this returns zero.

Public methodgetSurfaceOverflow
Finds surface overflow rate [m/s], assuming all water above StorageHeight is diverted.

If routing is enabled, this returns zero.

Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodGetVolume
Volume of water per area [m] contained on surface for a given depth
Public methodLimit
Limit state variables to allowed range, cannot be negative
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodPrepare
Prepare surface
Public methodPrepareSurfaceRouting
Whenever ManningM or Slope is updated, this needs to be called.
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Public methodValidate
Validate surface parameters
