net.simplace.client.simulation.lap.SimpleAutomaticIrrigation

Simple automatic irrigation component for layered soil water components

Available Mobile water iWM and retained water iWR is compared to the difference between cSoilWaterFieldCapacity and cSoilWaterWiltingPoint for layers above cIrrigationTriggerDepth.

If the ratio is lower than cIrrigationTriggerFactor, then irrigation is triggered, adding calculated AppliedIrrigationDepth to the incoming iRAIN and outputting the sum as RainAndIrrigation.

The module also determines whether runoff should be calculated (CalculateRunoff) if iRAIN exceeds cMaxRainWithoutRunoff.
