CatchmentKinematicWaveSurface Properties

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.

Area fraction. Default: depending on the surface type Unit: [-]

Horton, defined only for pervious surfaces.

Returns null if Infiltration is not Horton.

Infiltration calculator. If null, the surface is impervious.

True if infiltration shall occur also after rain has ended.

Default is true

.

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]

Manning number Default: depending on the surface type Unit: [m^(2/3)/s]

The slope of the catchment/channel.

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

Default: undefined Unit: [m]

Storage capacity Unit: [m]

Surface type, SurfaceType.

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.

Wetting capacity Unit: [m]
