== Modification to SlimWater3 == The FAO extraction method is slightly different. If WR-WHT15R > WClimit, then the extracted water per layer ist not calculated by extractionfactor but rather max(WR-WHT15R,Demandperlayer) SlimWater3.java is derived from SlimWater and ImprovedSoilWater as a SimComponent for transient simulations of the soil water balance of a multiple layer soil profile. For further details refer to the documentation of SlimWater.java The changes made in ImprovedSoilWater are exclusively related to the crop available water in the soil and the water uptake process by the crop. 1. Crop available water Whereas in SlimWater the proportion of extractable retained soil water (SAWR) is estimated as a quarter of the retained soil water ImprovedSoilWater estimates the proportion of the extractable soil water as a function of the development stage of the crop (DVS), a depletion factor (NominalDepletionEarly and NominaldepletionLate) and the crop water demand (EVAPO). The procedure distinguishes between a sensitive crop development stage (WaterSensitiveDVS), where the nominal depletion factor is high and a less sensitive development stage where the nominal depletion factor is lower. The final soil water depletion factor is then calculated as If DVS < StartWaterSensitiveDVS or DVS >= EndWaterSensitiveDVS, then according to Allen et al. 1996 (page 163, Footnote 2) (However, in Allen et al. 1996 ETc is used and not ET0!!!) WIKI_END \[ \begin{eqnarray} Depletion = NominalDepletionEarly + 0.04*(5.00 - EVAPO) \end{eqnarray} \]

If DVS is >= StartWaterSensitiveDVS and &lt; EndWaterSensitiveDVS, then

\[ \begin{eqnarray} Depletion = NominalDepletionLate + 0.04*(5.00 - EVAPO) \end{eqnarray} \]

Based on the depletion factor (Depletion) the proportion of the extractable water (EXT) in the retained soil water (WR in mm) in each soil layer is calculated as

\[ \begin{eqnarray} EXT[i] &=& \frac {EVAPO}{(1-Depletion) \cdot TWRH} \end{eqnarray} \]

where TWRH is the total amount of retainable water stored in the entire soil profile at field capacity (usually called "Available Water Capacity") and EVAPO is the reference evpotranspiration (both in mm).

N.B.: The calculation of the extraction factor for each layer is related to the total retainable water in the entire profile depth. As the profile depth is variable there could be a serious underestimation of EXT when increasing soil profile depth at early DVS when roots are still small. Therefore, the calculation of EXT at early DVS should not depend on TWRH

The amount of soil available water SAWR in the retained water fraction of each layer is then

\[ \begin{eqnarray} SAWR[i] &=& WR[i] \cdot EXT[i] \end{eqnarray} \]
