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

Simulates soil water. Part of the Gecros model.

Consult reference for description of algorithms.

This module calculates only the water balance part. For biomass producution there is the complementary module GecrosCrop. There is also a module Gecros, where crop and soil water part are calculated simultaneusly.
