Approach and Outcomes

WMS developed a detailed XP-RAFTS hydrological model and a detailed TUFLOW 2-dimensional hydraulic model in order to facilitate a flood impacts assessment of the proposed development. Existing and developed scenarios were simulated for a suite of design storms. Several design iterations were modelled to minimise the potential for impacts of site. Modelling results for the final design showed an overall decrease in flood levels and flood extent offsite with minimal change in flood velocity and flood behaviour.

The Challenge

Development of a solar farm was proposed at Yarranlea on the Darling Downs in Queensland. Due to concerns of the potential impact of the development on the behaviour of two identified overland flow paths in the region, a flood impacts assessment was required.
