Assessment of alternative groundwater management options in sugarcane growing area in the Burdekin Delta, North Queensland

摘要: Excessive irrigation has caused waterlogging in some parts of the Burdekin delta, while continued extraction groundwater reduced hydraulic head aquifer and resulted seawater intrusion. A management model was adapted to simulate impact various strategies on The estimated areas subject intrusion, along with simulated data from a crop yield model, were used mathematical programming account for economic impacts alternative options two neighbouring water board - North Water Board (NBWB) South (SBWB) delta. aggregate net revenues all are lower NBWB compared SBWB. In NBWB, revenue is highest when use also highest, lowest lowest. SBWB, relatively low maximum.
