1 SoilWater

The SoilWater module is a cascading water balance model that owes much to its precursors in CERES (Jones and Kiniry, 1986) and PERFECT(Littleboy et al, 1992). The algorithms for redistribution of water throughout the soil profile have been inherited from the CERES family of models. The water characteristics of the soil are specified in terms of the lower limit (ll15), drained upper limit(dul) and saturated(sat) volumetric water contents. Water movement is described using separate algorithms for saturated or unsaturated flow. It is notable that redistribution of solutes, such as nitrate- and urea-N, is carried out in this module. Modifications adopted from

PERFECT include: * the effects of surface residues and crop cover on modifying runoff and reducing potential soil evaporation, * small rainfall events are lost as first stage evaporation rather than by the slower process of second stage evaporation, and * specification of the second stage evaporation coefficient(cona) as an input parameter, providing more flexibility for describing differences in long term soil drying due to soil texture and environmental effects. The module is interfaced with SurfaceOrganicMatter and crop modules so that simulation of the soil water balance responds to change in the status of surface residues and crop cover(via tillage, decomposition and crop growth). Enhancements beyond CERES and PERFECT include: * the specification of swcon for each layer, being the proportion of soil water above dul that drains in one day * isolation from the code of the coefficients determining diffusivity as a function of soil water (used in calculating unsaturated

flow).Choice of diffusivity coefficients more appropriate for soil type have been found to improve model performance. * unsaturated flow is permitted to move water between adjacent soil layers until some nominated gradient in soil water content is achieved, thereby accounting for the effect of gravity on the fully drained soil water profile. SoilWater is called by APSIM on a daily basis, and typical of such models, the various processes are calculated consecutively. This contrasts with models such as SWIM that solve simultaneously a set of differential equations that describe the flow processes.

2 LateralFlowModel

Lateral movement of water is calculated from a user specified lateral inflow ('InFlow'). Lateral Outflow is the flow that occurs as a result of the soil water going above DUL and the soil being on a slope. So if there is no slope and the water goes above DUL there is no lateral outflow. KLAT is just the lateral resistance of the soil to this flow. It is a soil water conductivity. The calculation of lateral outflow on a layer basis is now performed using the equation: Lateral flow for a layer = KLAT * d * s / (1 + s2

(9)

DUL. (Note this allows lateral flow in any "saturated" layer, not just those inside a water table.) s = slope(m / m) L = catchment discharge width. Basically, it's the width of the downslope boundary of the catchment. (m) A = catchment area. (m2_{) NB. with Lateral Inflow it is assumed that ALL the water goes straight into the layer.}

Irrespective of the layers ability to hold it. It is like an irrigation. KLAT has no effect and does not alter the amount of water coming into the layer. KLAT only alters the amount of water flowing out of the layer

3 RunoffModel

Runoff from rainfall is calculated using the USDA-Soil Conservation Service procedure known as the curve number technique. The procedure uses total precipitation from one or more storms occurring on a given day to estimate runoff. The relation excludes duration of rainfall as an explicit variable, and so rainfall intensity is ignored. When irrigation is applied it can optionally be included in the runoff calculation. This flag (willRunoff) can be set when applying irrigation. Figure: Runoff response curves (ie runoff as a function of total daily rainfall) are specified by numbers from 0 (no runoff) to 100 (all runoff). Response curves for three runoff curve numbers for rainfall varying between 0 and 100 mm per day. The user supplies a curve number for average antecedent rainfall conditions (CN2Bare). From this value the wet (high runoff potential) response curve and the dry (low runoff potential) response curve are calculated. The SoilWater module will then use the family of curves between these two extremes for calculation of runoff depending on the daily moisture status of the soil. The effect of soil moisture on runoff is confined to the effective hydraulic depth as specified in the module's ini file and is calculated to give extra weighting to layers closer to the soil surface. Figure: Runoff response curves (ie runoff as a function of total daily rainfall) are specified by numbers from 0 (no runoff) to 100 (all runoff). Figure: Residue cover effect on runoff curve number where bare soil curve number is 75 and total reduction in curve number is 20 at 80% cover. Surface residues inhibit the transport of water across the soil surface during runoff events and so different families of response curves are used according to the amount of crop and residue cover.The extent of the effect on runoff is specified by a threshold surface cover (CNCov), above which there is no effect, and the corresponding curve number reduction (CNRed). Tillage of the soil surface also reduces runoff potential, and a similar modification of Curve Number is used to represent this process. A tillage event is directed to the module, specifying cn_red, the CN reduction, and cn_rain, the rainfall amount required to remove the tillage roughness. CN2 is immediately reduced and increases linearly with cumulative rain, ie.roughness is smoothed out by rain.

4 SaturatedFlowModel

When water content in any layer is below SAT but above DUL, a fraction of the water drains to the next deepest layer each day. Flux = SWCON x (SW - DUL) Infiltration or water movement into any layer that exceeds the saturation capacity of the layer automatically cascades to the next layer.

5 UnsaturatedFlowModel

For water contents below DUL, movement depends upon the water content gradient between adjacent layers and the diffusivity, which is a function of the average water contents of the two layers. Unsaturated flow may occur both towards the surface and downwards, but cannot move water out of the bottom of the deepest layer in the profile. Flow between adjacent layers ceases at a soil water gradient (gravity_gradient) specified in the SoilWater ini file. The diffusivity is defined by two parameters set by the user (diffus_const, diffus_slope) in the SoilWater parameter set (Default values, from CERES, are 88 and 35.4, but 40 and 16 have been found to be more appropriate for describing water movement in cracking clay soils). Diffusivity = diffus_const x exp(diffus_slope x thet_av) where thet_av is the average of SW - LL15 across the two layers. Flow = Diffusivity x Volumetric Soil Water Gradient

6 EvaporationModel

Soil evaporation is assumed to take place in two stages: the constant and the falling rate stages. In the first stage the soil is sufficiently wet for water to be transported to the surface at a rate at least equal to the potential evaporation rate. Potential evapotranspiration is calculated using an equilibrium evaporation concept as modified by Priestly and Taylor(1972). Once the water content of the soil has decreased below a threshold value the rate of supply from the soil will be less than potential evaporation (second stage evaporation). These behaviors are described in SoilWater through the use of two parameters: U and CONA. The parameter U (as from CERES) represents the amount of cumulative evaporation before soil supply decreases below atmospheric demand. The rate of soil evaporation during the second stage is specified as a function of time since the end of first stage evaporation. The parameter CONA (from PERFECT) specifies the change in cumulative second stage evaporation against the square root of time. i.e. Es = CONA t1/2_{Water lost by evaporation is removed from the surface layer of the soil profile thus this layer can dry}

below the wilting point or lower limit (LL) to a specified air-dry water content (air_dry). Figure: Cumulative Soil Evaporation through time for U = 6 mm and CONA = 3.5. For t <= t1Es = Eos For t > t1Es = U x t + CONA x Sqrt(t-t1)
