This dataset comprises mathematically modelled data of soil-water saturation, along vertical profiles, at 6 sites near the Namoi River, south-eastern Australia. The vertical profiles span the soil surface down to 10m deep, divided into 944 intervals. The 6 sites are located at different distances from the Namoi River and are split between 2 locations (Old Mollee and Yarral East). The distances from the river channel at each location are, Old Mollee: 50m, 140m and 320m, and Yarral East: 40m, 110m and 290m. The dataset underpins figures presented in Evans et al. (2018). The data were modelled as part of a PhD project funded by the Natural Environment Research Council and the National Trust.
Data have been produced using the HaughFlow model (Evans et al., 2018). HaughFlow is based on the 1D vertical Richards equation coupled with the 1D lateral Boussinesq equation and uses inputs of soil properties, river stage levels and climate parameters. Units of depth are in metres and water saturation is calculated as a proportion of the available pore spaces of the soil, producing values between 1 (100% saturated) and 0 (0% saturated), reported to 7 decimal figures. The Old Mollee 'Figure 6' datasets run from 01 July 2011 to 30 June 2015 and the Yarral East datasets run from 01 Jan 2013 to 30 June 2015. The Old Mollee 'Figure 7' dataset was modelled using alternative climate inputs and runs from 01 January 2004 to 31 December 2016.
