Brief description

A numerical model to simulate salt transport in the unsaturated zone of two selected sites of the Lockyer Valley, namely, Forest Hill and Tent Hill. Those two sites were selected as they had significant amounts of salt stored in their unsaturated zone, which extends to about 20 m. HYDRUS-1D of Šimůnek and colleagues (2008) was used to model water flow, solute transport, and root water uptake in those sites.

A total of twelve simulations were run, six for each site. Two irrigation options were considered, the first using the currently available water at each of the sites, and the second using PRW. For each of those options (1 and 2), two vegetation types were considered: shallow-rooted (series W) and deep-rooted (series D). An additional scenario was considered for the shallow-rooted vegetation where intensive irrigation was adopted; this option represented a worst-case scenario for salt mobilisation and transport. Simulation time was varied depending on the irrigation scenario, which was 100 years and 28 years for moderate and intensive irrigation scenarios, respectively.
