Saltwater intrusion is a severe environmental problem in coastal regions of Australia, resulting in loss of agricultural land at an alarming rate. This project aims to develop a three-dimensional mathematical model for the simulation and prediction of saltwater intrusion into complex coastal aquifers based on recent advances in the theory of anomalous diffusion, stochastic modelling and numerical methods. The parameters of the model such as hydraulic conductivity and porosity will be estimated using multifractal techniques based on field data at the microscale. Once validated from measurements, the model will be used directly for resource management and planning.

海水入侵是澳大利亚沿海地区一个严重的环境问题，导致农业用地以惊人的速度流失。本项目旨在基于异常扩散理论、随机模拟和数值方法的最新进展，建立模拟和预测咸水侵入复杂沿海含水层的三维数学模型。利用多重分形技术在微观尺度上对模型的水力导率和孔隙度等参数进行估计。一旦从度量中得到验证，该模型将直接用于资源管理和计划。
