Fact Sheet How Dams Work
Fact sheet How dams work December 2015 In South East Queensland, our drinking water is predominantly Flood mitigation sourced from dams, which collect run-off rainwater from our catchments and store it. Our dams provide a safe, secure and At its most basic level, flood mitigation is capturing water and cost-effective water supply, as well as help to mitigate floods. then releasing it at a slower rate, with the aim of minimising river levels downstream of the dam. When dams fill, they are designed to pass the excess water into the creek or river system they are built on. What is Full Supply Level? Dam release notification service The Full Supply Level of a dam is the approved water storage level of the dam for drinking and/or irrigation purposes. Seqwater offers a free dam release notification service, which provides subscribers with notifications when gated dams For un-gated dams, if inflows result in the water level rising release water or un-gated dams are spilling. above the Full Supply Level, the water will spill out of the dam. This spilling cannot be controlled. Subscribers to Seqwater’s dam release notification service will also be notified when higher outflows are occurring from For our gated dams (Wivenhoe, Somerset and North Pine), if a spilling dam due to high inflows resulting from rainfall in the inflows result in the water level rising above the Full Supply catchment. Level, Seqwater will make controlled releases for either flood mitigation or to protect the safety of the dam. These notifications advise caution downstream due to potential hazards to people and property. -

The construction of the dam involved the placement of around 4 million cubic metres of earth and rock fill, and around 140,000 Wivenhoe Dam was designed and built as a multifunctional cubic metres of concrete in the spillway section. Excavation facility. The dam was built upstream of the Brisbane River, of 2 million cubic metres of earth and rock was necessary to 80 kilometres from Brisbane City. At full supply level, the dam construct the spillway. holds approximately 2,000 times the daily water consumption needed for Brisbane. The Brisbane Valley Highway was relocated to pass over the dam wall, while 65 kilometres of roads and a number of new Wivenhoe Dam, along with the Somerset, Hinze and North Pine bridges were required following construction of the dam. -

Brisbane River Catchment Flood Study Monte Carlo Hydraulic Analysis Mitchell Smith1, Bill Syme2, Rory Nathan3
Brisbane River Catchment Flood Study Monte Carlo Hydraulic Analysis Mitchell Smith1, Bill Syme2, Rory Nathan3 1Senior Engineer, BMT WBM, Brisbane, Australia E-mail: [email protected] 2Senior Principal, BMT WBM, Brisbane, Australia 3Associate Professor, University of Melbourne, Melbourne, Australia The Brisbane River catchment is large (~15,000 km2), of which roughly half flows into Wivenhoe Dam. Rainfall across the catchment is temporally and spatially highly variable and antecedent conditions and initial dam levels significantly vary year-to-year. The influence of Wivenhoe Dam and the joint probability complexities of flows from Lockyer Creek and Bremer River rule out conventional approaches for deriving AEP flood events. To capture this variability a calibrated 1D hydraulic flood model was used to simulate 11,340 Monte Carlo flood events from downstream of Wivenhoe Dam through to Brisbane to derive AEP flood levels. An innovative process was developed to extract a representative set of 60 events grouped into 11 ensembles for the 11 AEPs from the 1 in 2 to 1 in 100,000. 1. INTRODUCTION Completed in February 2017, the Brisbane River Catchment Flood Study (BRCFS) (BMT WBM, 2017) (Aurecon, 2015) assessed the flood behaviour of the Brisbane River below Wivenhoe Dam, including the lower sections of major tributaries Lockyer Creek and the Bremer River (refer Figure 1). The study represents one of the most comprehensive hydrologic and hydraulic modelling assessments undertaken in Australia to date. The BRCFS’s major objective: The estimation of probabilistic riverine flood information for eleven Annual Exceedance Probabilities (AEPs), ranging from the 1 in 2 to the 1 in 100,000 AEP. -

Investigation of Scour Mitigation Methods for Critical Road Structures
University of Southern Queensland Faculty of Engineering and Surveying Investigation of Scour Mitigation Methods for Critical Road Structures A dissertation submitted by Peggy Chou Pei-Chen in fulfilment of the requirements of ENG4111 and ENG4112 Research Project towards the degree of Bachelor of Engineering (Honours) (Civil) Submitted October, 2016 Supervisor: Weena Lokuge and Buddhi Wahalathantri i Abstract The flood events that occurred in 2011 and 2013 in Queensland are notable for their devastating outcomes and damages to critical road structures. Bridges are necessary for the local community to travel and provide disaster relief during times of need. Therefore, it is important to identify methods that prevent bridge scour. To identify these countermeasures, a literature review of critical infrastructure scour prevention method was conducted. Methods that are appropriate were then analysed using the hydraulics software HEC-RAS. The Tenthill Creek Bridge was chosen as the framework of the analysis. Bridge scour depths were modelled and each method was compared. Combined with the HEC-RAS analysis, the feasibility analysis shows that a combination of collaring, riprap and wing walls is the most cost effective in decreasing the scour depths at piers and abutments. ii University of Southern Queensland Faculty of Engineering and Surveying ENG4111 Research Project Part 1 & ENG4112 Research Project Part 2 Limitations of Use The Council of the University of Southern Queensland, its Faculty of Engineering and Surveying, and the staff of the University of Southern Queensland, do not accept any responsibility for the truth, accuracy or completeness of material contained within or associated with this dissertation.
