Prof. Tom Baldock (Coastal and Ocean)

Please contact me if interested in undertaking a PhD at UQ in Coastal Engineering. Some potential projects are listed below, or you can form your own project. We have 3 new wave flumes with state of the art computer controlled wavemakers ready for use from September 2013. These will provide great opportunities for new experimental PhD projects.

Impact of Sea Level Rise on beaches

A long standing rule (the Bruun rule) to determine beach recession under sea level rise has never been rigorously tested. Using new wave flumes, this project would test this model and determine if it is correct for typical Australian beach conditions, and if not, why not. Novel beach nourishment techniques will also be tested to determine if they can mitigate sea level rise erosion.

Lagrangian measurement and modelling of nearshore hydrodynamics and sediment transport
Lagrangian measurements of hydrodynamics and sediment transport are extremely useful for developing process knowledge and modelling of coastal sediment transport, and UQ has pioneered recent advances. This project will extend this work using both laboratory and fieldwork, and combine the observations with numerical and analytical modelling.

Swash overtopping, setup and coastal inundation
Laboratory and field measurements will be used to consider the influence of overtopping of coastal barriers or beach berms on surf zone setup, and to quantify setup in the swash zone. The work will be useful for storm and cyclone surge predictions, coastal inundation and the modelling of coastal lagoons and creeks. Novel laboratory and field experiments will be carried out and the data compared to existing analytical and numerical models.

Dissipation of unsteady surf zone bores.

Current models for surf zone energy dissipation assume steady bores. This is not the conditions in reality. Our recent work suggests significant differences in the rate of energy dissipation for unsteady bores, which may lead to new models for surf zone waves. This project will be a combination of laboratory work and fieldwork using our new wave flumes and Gold Coast field site.

Theory of Momentum

Our group has pioneered new theory of momentum transfer between atmosphere and ocean. The transfer of momentum theory has not developed significantly since Miles’s work around mid-2000 century. Two publications in 2011 and 2012 have possibly set the direction for wind-wave research for the next decade or so. These two papers explains how wind-momentum impacted on the water surface is transferred downwards through the water column by Reynolds stresses, which were previously not thought to be generated by organised wave motion and how this additional momentum explains large storm surges when wind systems do not cross the coastline.

There are many possibilities for research in this area now, ranging from laboratory and field measurements to provide ideas on theory improvements through to applying this theory to storm surge modelling.

This project is conducted jointly by Dr Callaghan, Prof. Nielsen and Prof. Baldock

Prediction of wave propagation

Waves, with similar offshore parameters, propagate across the continental shelf to the surf zone and end up with different near-bed velocities (e.g., wave skewness and asymmetry). This project will apply various numerical models from simple analytical types through to RANS models to predict wave propagation and outside and inside surf zone near bed velocity. These predictions will be combined with field measurements (deep water, 20 metre depth and surf zone), to be collected during the project. Potential insights drawn from the modelling work combined with measurements are aimed at helping to improve near-bed velocity predictions.

This project is conducted jointly by Dr Callaghan, Prof. Nielsen and Prof. Baldock

Beach Erosion

Extreme beach erosion under climate change has been recently advanced by our group. The model promises much improved estimates however, there are many aspects that could be changed/modified to improve estimates. Possible improvements include simulation methods, tail shapes, application to other sites. As there are many different projects possible from this area of research, the project can include aspects from numerical modelling through to field data collection during large storms.

Wave interaction with ecosystems

Waves interact with many ecosystems including for example, salt marshes, coral reefs, sea grasses through applying physical forcing and through modulation of sediments (either in the water column or through transport). Our group has been successful in explaining such interactions for salt marshes and coral reef lagoons and reef flats. Further work is however required to better understand longer term trends and how environmental changes may influence these interactions.  The work would be undertaken in combination with ecologists to provide a whole of system understanding.

This project is conducted jointly by Dr Callaghan, Prof. Nielsen, Prof. Baldock and a group of Ecologists

Water exchange and mixing at the aquifer-ocean interface

Submarine groundwater discharge (SGWD) has been identified by International Geosphere-Biosphere Programme as an important contamination source for coastal marine and estuarine environments. Nutrient input associated with SGWD is threatening the Great Barrier Reef. Groundwater and seawater exchange driven by tides/waves at the shore contributes to SGWD significantly. However, no data of the water exchange rates exist. This project will measure time-varying groundwater flow and salinity distribution in the intertidal zone at two beaches to study near-shore water exchange and mixing. These unique data, providing basis for developing SGWD models, will improve the understanding and quantification of subsurface chemical fluxes to coastal waters.

Wave-induced transport and transformation of pollutants in coastal sediments

The sediments in many bays and estuaries in Australia are contaminated by pollutants due to discharge of waste from the river, groundwater and/or ocean outfall. These contaminants are however mobile and may return to the receiving water body through mass transfer processes near the sediment-water interface. As the contingent environmental regulations are reducing direct waste discharge to estuarine and coastal waters, the release of pollutants from contaminated sediments is becoming a primary concern for coastal water quality. On the other hand, the mobility of these pollutants may lessen the toxic impact on marine fauna. The aim of this study is to advance the much-needed general understanding of the fate of pollutants in contaminated sediments in coastal waters subject to wave actions using single-domain numerical models. We aim to develop a single-domain hydrodynamic model to simulate flows in the sediment and overlying water. This model will treat the sediment layer and the overlying water as a single domain and take into account the poro-elastic seabed behaviour, including the inertial and non-linear effects, and the wave-bed form interactions. A single-domain, multi-species transport model will also be developed and will be coupled with the hydrodynamic model and an existing chemical reaction model (Phreeqc-2). These models will allow us to study in detail the chemical release from the sediments to the overlying water body.

Finite mixing length modelling of turbulent diffusion

Our group has recently developed a new model for turbulent diffusion. The model promises much improved understanding and enhanced modelling of turbulent diffusion. Practical applications will range from rain snow and dust in the atmosphere through sediment and bubbles suspended in natural flows to various types of industrial reactors with turbulent flow. The work will be partly experimental, partly analytical and numerical modelling.

The contribution of onshore winds to coastal inundation

Our group has pioneered field measurements of wave setup. However the contribution from onshore winds to shoreline elevations during storms remains practically unknown. The project will involve field measurements of surf zone water levels and wind profiles.

Wave setup in river entrances

Field, laboratory and computer investigation for the purpose of developing proper tail-water conditions for Flood models. At the moment the profession is confused with respect to the possible contribution of wave setup. We know from field work at Brunswick Heads that for such fully trained rivers there is none. However this is not totally understood, cf Dunn et al (2000). The study would extend our experimental knowledge through partly trained entrances, e g Noosa, to completely untrained entrances.

Using dielectric spectroscopy to measure soil parameters:

Physical parameters of soils such as their strength and stiffness, which are dependent on the soil compaction, play an important role in Geotechnical Engineering in order to  characterise the soil behaviour.  Standardised procedures (for instance Proctor and Oedometer tests) have been introduced to investigate the mechanical soil parameters at different compaction and stress states.  The project involves an experimental investigation on these parameters for a broad range of fine-grained soils using standardised procedures.  Additionally, dielectric spectroscopy, as an upcoming investigation technique, will be applied to measure the dielectric properties during the standardised testing of soils.  This project intends to advance the knowledge of the coupled mechanical and dielectric soil properties.  You will have the chance to conduct standardised tests for the determination of mechanical parameters of soils in combination with the determination of the complex dielectric parameters.  This research project is an innovative approach in Geotechnical Engineering to combine mechanical, hydraulic and dielectric tests to increase the information from soil testing.  You will conduct mechanical testing in combination with dielectric measurements.  You will analyse the results and represent them in a graphical form.

Pore structure analysis of granular soils:

Erosion processes in soils are dependent on the pore constriction size distribution of the soil itself.  If the pore constrictions are large enough, particles can move from one pore to the other.  In this connection, the pore constriction defines the size of the ‘door’ through which a particle must pass to enter another ‘room’ or pore void.   There are many techniques available to calculate the pore constriction size distribution based on the grain size distribution of a soil.  A newly developed model based on a three-dimensional sphere packing algorithm allows for the introduction of the porosity to develop a more realistic pore constriction size distribution.  The aim of the project is the implementation of percolation tests which are then analysed using the introduced model.  The aim is to quantify the amount of fine particles which can be removed out of a soil which is in itself not ‘filter-stable’.  This means that the fine fraction of the soil could be removed from the solid skeleton.  This kind of erosion process, also called suffusion, is still not fully understood.  You have the chance to contribute to an ARC Discovery project dealing with the problem of erosion processes.  You will conduct physical column test and you will analyse them with the model available.

Risk assessment and cost-effectiveness analysis of rehabilitating open cut coal mine spoil areas:

Risk assessment and cost-effectiveness analysis techniques are becoming an essential tool in defending the choice of rehabilitation strategy for open cut mines.  An existing risk assessment and cost-effectiveness analysis tools developed for the rehabilitation of open cut coal mine spoil areas will be applied to different mine site domains, and the cost-effectiveness of different rehabilitation strategies assessed.

Laboratory wick drain model experiments:

This is a continuation of a research project commenced in 2009 with the commissioning of a purpose-built laboratory apparatus.  Wick drains are routinely used at low-lying soft soil sites requiring the addition of fill to bring them above a design flood level.  Their purpose is to speed-up consolidation of the soft soils under the weight of the fill.  Theoretically, they should increase the rate of consolidation by several orders of magnitude.  However, in practice they only speed-up consolidation by at most 10 times.  The laboratory wick drain model experiments are aimed at explaining why this is so.

Numerical analysis of laboratory wick drain model results (Dr Dorival Pedroso is co-supervisor)

The purpose of this research project is to validate and calibrate available numerical analyses against the results of laboratory wick drain model experiments to improve their predictive capability for field application.

Comparison of laboratory vs. field SWCC data (Dr Dorival Pedroso is co-supervisor)

The Soil Water Characteristic Curve (SWCC) is a key relationship for describing the behaviour of unsaturated geomaterials.  It is conventionally determined in the laboratory, but SWCC data can also be collected from field samples.  Comparisons between laboratory and field SWCC data can show dramatic differences, due to the effects of material structure and cementation in the field, which may be destroyed on sampling and sample preparation for laboratory testing.  The aim of this project is to research this further.

Comparison of alternative methods for estimating the total, osmotic and matric suction of soils

Soils can exist under suction.  By definition, the matric or capillary suction is zero at and below the water table, while the osmotic and hence total suctions can have finite values both above and below the water table, depending on the salinity of the pore fluid.  There are several methods available for measuring soil suctions and the aim of the research project is to compare the results obtained by different methods.

Adding value to closed coal mine workings in the growth corridor of the Ipswich Coalfields

Closed coal mines in the vicinity of urban and industrial growth corridors have the potential to have value added by targeted engineering design and construction.  This research project, in collaboration with industry, will seek opportunities to add value to closed coal mines to allow a higher level of post-mining development than is possible through conventional mine site rehabilitation.

Optimising the earthworks involved in reshaping open strip coal mine spoil piles

Surface coal mining by dragline leaves a legacy of surface disturbance in the form of spoil piles.  The rehabilitation of spoil pile areas involves substantial earthworks, which constitute the major cost of rehabilitation.  Minimising the amount of earthworks required minimises the cost of rehabilitation.  Typically, spoil piles are reshaped from the angle of repose of the spoil (about 37 degrees) to a constant angle of less than 10 degrees.  An alternative strategy would be to reproduce, as closely as possible, the pre-mining distribution of slope angles and lengths, which can be determined from pre-mining topographic plans.  By comparing the pre-mining and post-mining topographic plans, it is possible to determine the minimum earthworks required to mimic the general pre-mining landform.

Mine haul road pavement design, construction and maintenance (Dr Alexander Scheuermann is co-supervisor)

Mine haul roads are unpaved and must carry huge loads at high speed and be constructed of the available mine spoil or waste rock.  There is a need to optimise their design, construction and maintenance, and make them most cost-effective.  This project will potentially involve conventional and non-destructive testing of haul road pavements, and pavement materials, and the development of improved design, construction and maintenance methods and predictive monitoring

Settlement of high coal mine spoil (Dr Marek Zbik is co-supervisor)

Self-weight, saturation and weathering-induced settlement of high coal mine spoil.  This will be a laboratory-based study carried out at a range of scales on scalped (large-sized particles removed) coal mine spoil materials of various types.  Testing will include dry, wet-up and saturated large-size consolidometer and large size direct shear box testing, and small-scale testing under more controlled conditions.  The project lends itself to a future undergraduate thesis or Masters project.

Behaviour of clay-rich coal tailings (Dr Marek Zbik is co-supervisor)

Problematic clay-rich coal mine tailings: Scale-up of vane shear tests.  The study will be based at three different scales: Chemical Engineering laboratory, Geomechanics laboratory and field at a mine site.  Testing will include the use of vane rheometer, a small-scale vane shear device, and field vane shear.  The study aims to characterise the in situ shear strength with that observed by rheology and vane shear testing (remoulded and undisturbed) under a range of testing conditions (steady and dynamic).

Auger displacement piling (Dr Alex Scheuermann is co-supervisor)

Analysis of the behaviour of auger displacement piles (ADP) in cohesive soil.  Auger displacement piles have been used as foundation elements for structures or for soil improvement (rigid inclusions) of foundations of embankments and concrete slabs for many decades.  Over the last decade this technique has grown rapidly due to its effectiveness and the fact that no spoil is generated during the installation process.  Different from conventional bored piles, ADP's displace the soil laterally during the installation process, which results in higher pile capacities in granular and cohesive soils.  The displacement process of ADPs in cohesive soils has been investigated in detail by UQ since 2008.  From July 2012 until February 2013 field tests with full-scale piling equipment will be carried out at Lawnton (Northern suburbs of Brisbane) as the key component of this research project.  The aim of the field tests is in to measure installation effects, stresses and displacements in the soil during the installation of auger displacement piles.  Your main activities for this project will involve the calibration and analysis of test data from the TDR, inclinometers and piezometers.

Dam break wave: theoretical analyses

Dam break waves have been responsible for numerous losses of life: e.g., the catastrophes of the St Francis dam (USA 1928) and of the Malpasset dam (France 1959). Another situation is the bombing of the Ruhr dams by the "Dam Busters" during Word War II on 16/17th May 1943. Related situations include flash flood runoff in ephemeral streams, debris flow surges and tsunami runup on dry coastal plains. In all cases, the surge front is a sudden discontinuity characterised by extremely rapid variations of flow depth and velocity. Dam failures motivated basic studies on dam break wave, including the milestone contribution by RITTER (1892) following the South Fork (Johnstown) dam disaster (USA, 1889). Physical modelling of dam break wave is relatively limited despite a few basic experiments. Theoretical modelling has also been limited despite someoustanding contributions.
In this project, some basic dam break wave applications are reviewed, and new analytical solutiona of the dam break wave are developed for Newtonian and non-Newtonian thixotropic fluid.

Energy dissipation and air entrainment on stepped spillways

In the last few decades, a number of experimental investigations of stepped spillways took placewith a focus on the energy dissipation and air-entrainment processes on stepped spillways. Dimensional analysis and dynamic similarity considerations highlighted the potential for scale effects in small-size laboratory studies.  Herein a physical study is performed on a relatively large size stepped spillway channel. Several stepped chute configurations are tested. Detailed air-water flow measurements are conducted systematically for a range of flow conditions at large Reynolds The relationship between rate of energy dissipation and turbulence levels is investigated.

Unsteady open channel flow: physical modelling

In an open channel, a sudden drop in free-surface elevation is associated with the development of a negative wave. While some simple analytical solution is widely described in textbooks, little research was conducted to date on the unsteady turbulence properties beneath negative waves. A series of new physical experiments will be conducted in a rectangular channel. The unsteady free-surface profile and turbulence characteristics will be measured in a negative wave propagating upstream against an initially steady flow using non-intrusive acoustic displacement meters, video imagery and acoustic Doppler velocimetry (ADV).

Fish passage in culverts: hydraulic engineering

This project will review the design of culvert to facilitate fish passage. After a review of the literature, the project will focus on desings suitable to the Australian environment ad the Australian fauna.

Hydrodynamics of tidal bores

When a river mouth has a flat, converging shape and when the tidal range exceeds 6 to 9 m, the river may experience a tidal bore {http://www.uq.edu.au/~e2hchans/tid_bore.html}. A tidal bore is basically a series of waves propagating upstream as the tidal flow turns to rising. It is a positive surge. As the surge progresses inland, the river flow is reversed behind it. New research into the unsteady hydrodynamics of tidal bores and postive surges will be investigated in a large-size physical model.

Hydraulic engineering of stepped chutes. Application to stepped spillway design

In recent years, the design floods of a number of dams were re-evaluated and the revised flows were often larger than those used for the original designs. In many cases, occurrence of the revised design floods would result in dam overtopping because of the insufficient storage and spillway capacity of the existing reservoir. A number of overtopping protection systems were developed for embankments and earthfill dams. These include concrete overtopping protection systems , timber cribs, sheet-piles, riprap and gabions, reinforced earth, Minimum Energy Loss weirs, and the precast concrete block protection systems developed by the Russian engineers. New physical tests will be a conducted ina a large-size facility to optiise present design guidelines.

Hydraulic design of energy dissipators for hydraulic structures

The optimum design of stepped spillway & energy dissipation systems can provide aneconomical solution for additional water resources & more efficient water distribution systems. Applications range from rural to large water systems including urban drainage networks. Their turbulence characteristics & energy dissipation performances are critical issues that are poorly understood. This project aims to gain new expert knowledge & to develop new radical design guidelines for the design of energy dissipators used for spillway, water supply & drainage systems. This will be achieved through an undergraduate thesis (preferably in a group of 2).

Turbulent mixing in sub-tropical estuaries

Turbulent mixing in sub-tropical estuaries Dispersion of matter in natural river systems is of considerable importance, particularly in relation to the transport of nutrients, sediment and toxicants into ecosystems as a result of stormwater runoff and wastewater discharges. The project aims to improve our basic understanding of turbulent mixing and the influence of anthropogenic releases in small subtropical estuaries, and to develop improved predictive models to assist with the management and monitoring of natural ecosystems. This will be achieved through a Ph.D. research project integrating basic water engineering and environmental sciences. The project is part of an active cross-institutional multidisciplinary research effort involving researchers from the School of Civil Engineering (UQ) and from Industry.

 Experimental study of the similitude between air and water wake flows downstream of a cylinder

Roughness and scale effects applied to pollutant dispersion Predicting pollutant dispersion in both transportation systems (cars, planes) and in environmental flows is particularly interesting for the purpose of public health and protecting ecosystems. Namely, pollution of outside air was classified as a carcinogenic agent in 2013. This is the reason why more studies have to be undertaken to improve our knowledge of this topic. To date, the dynamics of nanoparticles ejected from exhaust pipes of conventional engines is still not well understood. By assessing their behaviour, the goal is to avoid (as far as possible) some of their negative impacts and to provide technological solutions to reduce their emissions and to give/put forward new recommendations. Studying dispersion of pollutants in coastal or estuarine environments should bring in-depth knowledge of key parameters controlling their displacements and thus give adapted answers to maritime pollution. It is worthwhile to note that the common point between these two applications, except for the environmental aspect, is turbulence. Indeed, particles from exhaust gas and pollutant/sediment in coastal environments are released in turbulent flows whose dynamics are affected by turbulent structures associated with these flows . Better knowledge of the turbulence flow properties (intensity, length and time scales) is then required to identify key parameters having a major impact on the dynamics of the particles .

In this context, the proposed research work involves the University of Queensland (Department of Civil Engineering) and ESTACA (CERIE). Previous exchanges between Hubert Chanson (UQ) and Frederic Murzyn (ESTACA) since 2002 have pointed out some strong and common research fields including environmental two-phase flows. The aim of this new research project is to extend and enhance this collaboration through a PhD research project dealing  with pollutant dispersion in turbulent flows.

Stochastic modelling of convective wind hazard

Convective wind storms cause significant damage to buildings and infrastructure throughout the world. Understanding the risk they pose is therefore of utmost importance if these damages are to be mitigated. This project aims to better quantify the wind hazard these events pose by developing a physical event-based stochastic modelling approach that can be used to estimate convective wind risk (including uncertainty) throughout Australia. The project will involve development of, for example, new methods to stochastically simulate convective wind fields and storm tracking behaviour.

Characterisation of non-stationary wind loads on structures

Non-stationary wind storms such as downbursts and tornadoes are responsible for damage to buildings and infrastructure throughout the world. Despite this, the precise manner by which they load structures is still unclear. This project aims to experimentally investigate the fundamental way that non-stationary, non-boundary layer wind fields load simple structures. A primary responsibility for the successful student will be the implementation of a small multi-fan wind tunnel.
