SurfaceWater

PondModel{FT, D, R} <: AbstractSurfaceWaterModel{FT}

A stand-in model for models like the snow or river model. In standalone mode, a prescribed soil infiltration rate and precipitation rate control the rate of change of the pond height variable η via an ODE. In integrated LSM mode, the infiltration into the soil will be computed via a different method, and also be applied as a flux boundary condition for the soil model.

• domain: The domain for the pond model

• runoff: The runoff model for the pond model

PrescribedRunoff <:  AbstractSurfaceRunoff

The required input for driving the simple pond model: precipitation, as a function of time, soil effective saturation at a depth Δz below the surface, as a function of time, and soil parameters, which affect infiltration.

function Pond.surface_runoff(
    runoff::PrognosticRunoff{FT},
    Y::ClimaCore.Fields.FieldVector,
    p::NamedTuple,
    t::FT,
) where {FT}

Extension of the Pond.surface_runoff function, which computes the surface runoff, for use in an LSM when the runoff is determined prognostically.
