Properties
  NameDescription
Public propertyApplyEvaporationOnRain
When raining, if true the evaporation is applied at the beginning of the time step, correcting the net rain and limited by the rain. If false, evaporation is applied on non-empty storages in the catchment and can exceed the rain.

In dry periods, this is not used, evaporation is always applied on storages.

(Inherited from CatchmentSurface.)
Public propertyAreaFraction
Area fraction. Default: depending on the surface type Unit: [-]
Public propertyHorton Obsolete.
Horton, defined only for pervious surfaces.

Returns null if Infiltration is not Horton.

(Inherited from CatchmentSurface.)
Public propertyInfiltration
Infiltration calculator. If null, the surface is impervious.
(Inherited from CatchmentSurface.)
Public propertyInfiltrationAfterRain
True if infiltration shall occur also after rain has ended.

Default is true

.
(Inherited from CatchmentSurface.)
Public propertyLength
The length of the subcatchment/channel.

The model assumes a prismatic flow channel with rectangular cross section. The channel bottom width is computed from catchment area and length.

If not defined, the average length of the base catchment is used.

Default: undefined Unit: [m]

Public propertyManningM
Manning number Default: depending on the surface type Unit: [m^(2/3)/s]
Public propertySlope
The slope of the catchment/channel.

If not defined, the average slope of the base catchment is used.

Default: undefined Unit: [m]

Public propertyStorageCapacity
Storage capacity Unit: [m]
(Inherited from CatchmentSurface.)
Public propertySurfaceType
Surface type, SurfaceType.
Public propertyUseReverseDraining Obsolete.
Revert to old draining order. Set to true to drain in same order as in MOUSE engine.

Reverse draining drains in order: wetting, storage, depth. Hence, when storages are full, wetting and storage will be drained and not depth, depth will be higher and give more runoff. This is visible in low-flow conditions.

(Inherited from CatchmentSurface.)
Public propertyWettingCapacity
Wetting capacity Unit: [m]
(Inherited from CatchmentSurface.)

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 methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodPerformTimeStep
Take timestep for surface, filling storages and evaluating evaporation and infiltration
(Inherited from CatchmentSurface.)
Public methodRecalculateRunoff
When state has been updated on surface (the Depth), recalculate runoff to match the new depth.
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
