This project examined the surface water management rehabilitation options to allow Iluka to complete the Catchment Mining Rehabilitation Plan (CMRP). This work involved both hydrologic modelling to determine flow rates for a range of ARI events and hydraulic modelling to identify the pattern and distribution of flow for each ARI event.

We developed designs for rehabilitation and construction of creeks, gullies and waterways and provided recommendations for field studies to examine erodibility of the landscape and the effectiveness of erosion controls.  This work advanced the understanding between the pre-mining and post-mining (lowered) landscape to identify potential erosion impacts to the surface water features.
