public class SoilEvaporationReduction
extends net.simplace.sim.model.FWSimComponent

Calculates the soil evaporation reduction coefficient K_r using formulas from (FAO 56).

Implemented methods: Allen et al (1998), equations 73 and 74.

For full documentation of the formulas please check the original reference (FAO 56)

EvaporationReduction

protected double EvaporationReduction()

Calculates K_r. Allen et al (1998) specifies K_r = 1 when soil surface is wet, which also the case here, as when WM > 0, WR = FC and D_e will be zero.

fillTestVariables

public HashMap<String,net.simplace.sim.util.FWSimVariable<?>> fillTestVariables(int aParamIndex,
 net.simplace.sim.model.FWSimComponent.TEST_STATE aDefineOrCheck)

called for single component test to check the components algorithm.
