CatchmentSurface Class |
Catchment surface class, handling wetting loss, storage loss, infiltration and evaporation
If Infiltration is not defined, the surface is assumed to be impervious, and no infiltration is applied.

SyntaxThe CatchmentSurface type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | CatchmentSurface |
Default constructor
|
Properties| Name | Description | |
|---|---|---|
 | ApplyEvaporationOnRain |
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. |
| Horton | Obsolete.
Horton, defined only for pervious surfaces.
Returns null if Infiltration is not Horton. |
| Infiltration |
Infiltration calculator. If null, the surface is impervious.
|
| InfiltrationAfterRain |
True if infiltration shall occur also after rain has ended.
Default is true . |
| StorageCapacity |
Storage capacity
Unit: [m]
|
| UseReverseDraining | 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. |
| WettingCapacity |
Wetting capacity
Unit: [m]

Methods| Name | Description | |
|---|---|---|
 | DrainStorage |
Drains water for the given storage (eg. infiltration)
|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| FillStorage |
Fills a specific storage with a giving amount of inflow (rain).
This procedure will update the amount of inflow not added to the storage,
and returns the new depth of the storage.
|
 | 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.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| PerformTimeStep |
Take timestep for surface, filling storages and evaluating
evaporation and infiltration
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Fields| Name | Description | |
|---|---|---|
 | Depth |
Depth of water on sub-catchment.
State variable.
Unit: [m]
|
| DepthOld |
Depth of water at the previous time step.
Computational variable.
Unit: [m]
|
| EvapActual |
Actual evaporation.
Reporting variable.
Unit: [m/s]
|
| InfiltrationActual |
Actual infiltration.
Reporting variable.
Unit: [m/s]
|
| InfiltrationActualOld |
Infiltration of last time step
Reporting variable.
Unit: [m/s]
|
| InfiltrationPotential |

State variable.
Unit: [m]
|
| StorageLossOld |
Storage loss depth at the previous time step.
Computational variable.
Unit: [m]
|
