Upper Brisbane River Bank Stabilisation
The Water & Carbon Group prepared a riparian revegetation plan, with revegetation data overlaid onto a range of catchment improvement designs, such as re-profiling. The overall project design work forms part of a delivery package for SEQ Water to put to tender.
Project Summary
The Water & Carbon Group were engaged by Alluvium Consulting in 2015 to undertake site assessments and identify opportunities for restoration. Riparian vegetation planting plans were then prepared and approved by Seqwater that included treatments for re-profiled river banks. In 2016, WCG partnered with GWT Earthmoving and were successful in being awarded 2 bank stabilisation projects at Lower Cressbrook. The civil works were shortly undertaken, followed by plantings. Both sites have continued to be monitored and maintained by the Water & Carbon Group over the past 3 years.
Throughout recent years, the Lower Cressbrook area has been affected heavily by floods, particularly in 2011. A large amount of damage has been caused to the Upper Brisbane River banks as a result, leaving several river banks in need of restoration and stabilisation in preparation for any similar events in the future.

Solution
The Water & Carbon Group undertook site assessments before developing riparian revegetation planting plans which were then approved by Seqwater. This included high density plantings graded throughout the river banks reintroducing structural complexity (including native grasses/groundcovers) in order to reinstate biodiverse riparian zones. Civil works and planting was initiated at two sites between August and October 2016 with monitoring and maintenance to occur over 3 years.
Outcomes
As of 2018, the project is still ongoing with regular monitoring and maintenance taking place. The project appears to be exceeding expectations despite being affected by additional flooding, frost damage and seasonal dry weather. Despite the setbacks, the project has been completed to an extremely high quality, whilst staying within its budget and time constraints.
