SIM

SIM is a user-friendly standalone windows software, which is developed to help growers, agronomists and irrigation engineers to develop irrigation schedules using basic information of soil water balance, crop characteristics and atmospheric conditions. SIM can be used to 1) Estimate reference evapotranspiration (ET0) using three different approaches, including the modified FAO Penman-Monteith (FAO-PM), Hargreaves model and the Blaney‒Criddle equation; 2) Estimate irrigation water requirements for single irrigation events using different methods; and 3) develop irrigation schedules using the ET0-Kc approach and Evapotranspiration–Soil Water Balance  (ET-SWB) methods. The SIM software was initially developed by the end of 2022, with its theoretical framework and methodology finalized by June 2023. The software underwent thorough testing and debugging, with all identified issues resolved by the end of 2024. The final version was released for reliable public use.
