ICatchmentKinematicWaveSurfaceData Properties

The ICatchmentKinematicWaveSurfaceData type exposes the following members.

Properties
  NameDescription
Public propertyAreaFraction
Area fraction of surface type. Unit: [-].
Public propertyHortonDryExponent Obsolete.
Time constant for dry period (inverse Horton's equation). Unit: [1/s]. Only applicable for the Pervious surfaces.
Public propertyHortonEndInfiltrationRate Obsolete.
Infiltration rate at end. Unit: [m/s]. Only applicable for the Pervious surfaces.
Public propertyHortonStartInfiltrationRate Obsolete.
Infiltration rate at start. Unit: [m/s]. Only applicable for the Pervious surfaces.
Public propertyHortonWetExponent Obsolete.
Time constant for wet period (horton's exponent). Unit: [1/s]. Only applicable for the Pervious surfaces.
Public propertyInfiltration
Infiltration calculator. This defines whether the surface is pervious.
(Inherited from ICatchmentSurfaceData.)
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 M 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]. Not applicable to ImperviousSteep.
Public propertyWettingCapacity
Wetting capacity. Unit: [m].
