Parameters:	rainfall : rainfall for time step cmd : previous CMD value Mf : interim CMD value d : threshold value d2 : scaling factor applied to d n : scaling factor (default = 0.1) Default value is suitable for most cases (Croke & Jakeman, 2004)
Returns:	effective rainfall

proc calc_ET_from_E(e, evap, Mf, f, d: float): float {...}{.stdcall, exportc, dynlib,
    raises: [], tags: [].}

Calculate evapotranspiration from evaporation.

Parameters:	e : temperature to PET conversion factor (a stress threshold) evap : evaporation for given time step. Mf : Catchment Moisture Deficit prior to accounting for ET losses (M_{f}) f : calibrated parameter that acts as a multiplication factor on d d : flow threshold factor
Results:	estimate of ET

proc calc_ET(e, evap, Mf, f, d: float): float {...}{.stdcall, exportc, dynlib,
    raises: [], tags: [].}

Deprecated function - call calc_ET_from_E instead.

proc calc_ET_from_T(e, T, Mf, f, d: float): float {...}{.stdcall, exportc, dynlib,
    raises: [], tags: [].}

Calculate evapotranspiration based on temperature data.

Parameters f and d are used to calculate g, the value of the CMD which the ET rate will begin to decline due to insufficient water availability for plant transpiration.

Parameters:	e : temperature to PET conversion factor (a stress threshold) T : temperature in degrees C Mf : Catchment Moisture Deficit prior to accounting for ET losses (M_{f}) f : multiplication factor on d d : flow threshold factor
Returns:	estimate of ET from temperature (for catchment area)
