These are combined through the FAO56 methodology using gridded rainfall and two reference evapotranspiration (ET_o) products to find actual evapotranspiration as AET = ET_o x K_c, providing six ET_o-K_c combinations. Results indicate this study method can effectively assess irrigation water use over a range of catchment sizes from ~6000 to ~600,000 ha, although issues arise when regions have a designated low allocation volume for that season (less than40%). Comparisons with the Standardised Precipitation Index (SPI) and Evaporative Stress Index (ESI) show that the proposed method is robust to the rapid onset and short-term droughts, However, its performance was poor during the long term droughts with low water allocation years. The study results during these years has been predominately attributed to water stress in certain crops being undetected, agricultural managers skipping annual crop commodities as well as stock and domestic water use making up larger portions of total water use. This is a limitation of this approach, although when only comparing results in years with greater than 40% allocations, the results improved significantly showing it can monitor water use effectively. When adequate water is available, this approach is able to accurately predict irrigation water use for the sites examined.]]> Wed 28 Feb 2024 14:57:23 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47612 Tue 24 Jan 2023 11:35:47 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:863 Sat 24 Mar 2018 08:31:31 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3403 Sat 24 Mar 2018 07:21:41 AEDT ]]>
