These are combined through the FAO56 methodology using gridded rainfall and two gridded reference evapotranspiration (ET_o) products to estimate actual evapotranspiration, providing six K_c - ET_o combinations which are then compared to actual/recorded irrigation volumes from test sites. The method was tested over an almond farm, two vineyards and a cotton field; in addition to Goulburn-Murray Water’s (GMW) individual farm scale sites with unknown crops, all located within Australia. The developed approach provided estimated irrigation volumes that closely matched measured data for almond and cotton farms, while vineyards returned less accurate results due to localised management techniques that do not agree with land management assumptions made. The results from GMW showed some indication of the irrigation water use, although more details of the site being assessed needs to be available (i.e. crop type and extent). This study demonstrates the ability of certain remote sensing K_c relationships for sensing irrigation water use and shows the potential applications of the developed approach in monitoring irrigation over paddock scale environments.]]> Mon 26 Jun 2023 14:59:03 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44818 Mon 24 Oct 2022 09:38:29 AEDT ]]>
