NOTES ON WATERTRACK OPTIMISER
TM
WaterTrack Rapid
TM
is a simple and easy to use water balance model which is rigorous
in its calculations but lumps all major elements in to a single seasonal loss
per element. For a detailed breakdown
of losses into seepage and evaporation in each element of the irrigation system
on a daily basis, WaterTrack Optimiser
TM should be used. WaterTrack Optimiser
TM
also allows prediction forward to optimise planted area decisions for various water
availabilities and can provide assessment of infrastructure changes on water use
(see

RESULTS DISCLAIMER
Output of this model is based on minimal data together with an understanding of the
processes of water movement on an irrigated farm. It should be used with caution and supported by other measures of water movement on the farm. WaterTrack
accepts no liability under any circumstances for decisions based on this output.
MODELLING ASSUMPTIONS
- Data input by irrigators is accurate.
- Crops are healthy and fully irrigated for reporting period for crop transpiration calculations.
- Calculated Crop Water Requirements includes both plant transpiration and
evaporation from the soil and plant.
- Rainfall on all areas except irrigated fields is ignored, unless runoff captured is Land Surface Diversion.
- Land Surface Diversions (the new Murray Darling Basin Commission term) includes:
- on-farm stormwater runoff harvested,
- any surface water harvested from drainage paths adjacent to farm,
- any flood or overland flow waters harvested from rivers or creeks running overland once the water “breaks the banks”.
- Water supplied and lost is apportioned evenly per green hectare.
- Overlapping crops should be handled independently ie:
two different runs each for different time periods and crops even if overlapping.
This means the grower must have a reasonable idea of how much water (gross) was
supplied to each crop OR use WaterTrack OptimiserTM.
- WaterTrack DividerTM calculates rainfall runoff based on both the irrigated and dry sections of an irrigated field. For example if rain occurs during an irrigation period and the irrigation took say 6 days and the rain occurred on day 3, then 50% of the green area is assumed to have been irrigated & 50% not. This split is used for calculating the effective rainfall only, the field is treated as a whole for all other calculations.
- The farm can be treated as one large field for simplicity or run
with as many fields treated separately as the grower wishes for more detailed results.
