Runoff

Runoff types and functions

ClimateMachine.Land.Runoff.AbstractPrecipModel — Type

AbstractPrecipModel{FT <: AbstractFloat}

source

ClimateMachine.Land.Runoff.DrivenConstantPrecip — Type

DrivenConstantPrecip{FT, F} <: AbstractPrecipModel{FT}

Instance of a precipitation distribution where the precipication value is constant across the domain. However, this value can change in time.

Precipitation is assumed to be aligned with the vertical, i.e. P⃗ = Pẑ, with P<0.

Fields

mp
Mean precipitation in grid

source

ClimateMachine.Land.Runoff.AbstractSurfaceRunoffModel — Type

AbstractSurfaceRunoffModel

Abstract type for different surface runoff models. Currently, only NoRunoff is supported.

source

ClimateMachine.Land.Runoff.NoRunoff — Type

NoRunoff <: AbstractSurfaceRunoffModel

Chosen when no runoff is to be modeled.

source

ClimateMachine.Land.Runoff.CoarseGridRunoff — Type

CoarseGridRunoff{FT} <: AbstractSurfaceRunoffModel

Chosen when no subgrid effects are to be modeled.

ClimateMachine.Land.Runoff.compute_surface_grad_bc — Function

function compute_surface_grad_bc(soil::SoilModel,
                                 runoff_model::CoarseGridRunoff,
                                 precip_model::AbstractPrecipModel,
                                 n̂,
                                 state⁻::Vars,
                                 diff⁻::Vars,
                                 aux⁻::Vars,
                                 t::Real
                                 )

Given a runoff model and a precipitation distribution function, compute the surface water flux normal to the surface. The sign of the flux (inwards or outwards) is determined by the magnitude of precipitation, evaporation, and infiltration.

                                 )

Given a runoff model and a precipitation distribution function, compute the surface water flux normal to the surface. In this case, no runoff is assumed. The direction of the flux (inwards or outwards) depends on the magnitude of evaporation, precipitation, and infiltration.
