public class LintulWaterStress
extends net.simplace.sim.model.FWSimComponent
LintulWaterStress calculates the transpiration reduction factor (TRANRF) based on the ratio between actual crop transpiration (TRAN in mm) and potential crop transpiration (PTRAN in mm):
\[ \begin{eqnarray} TRANRF &=& MIN(1,\frac{TRAN}{PTRAN} \cdot \frac{1}{DroughtTolerance}); \end{eqnarray} \]TRAN and PTRAN are provided by the SimComponent EvapTran.java. The SimComponent forsees another factor of "drought tolerance" (besides TRANCO in the SimComponent EvapTran.java) to dampen the effect of drought stress by directly reducing TRANRF, but changing the "DroughtTolerance" factor to values other than unity is strongly discouraged.
