  • It is well known that the simple gradient diffusion model fails in relation to many geophysical and industrial mixing processes where the important eddies are not infinitesimally small compared to the scales considered. Finite mixing length models are therefore an active area of research, e g Nielsen & Teakle (2004).

    The present project will be mainly experimental, studying concentration profiles of light (rising) versus heavy (sinking) particles with numerically similar rise/sinking velocities in the same flow.

  • Much of the sand which migrates along the beaches travels in suspension.

    The mechanisms which govern such sediment suspensions are therefore of interest.

    For some combinations of wave and sand parameters stratification plays an important role. That is, for these parameter combinations, the density of the water-sand-mixture near the bed is sufficiently increased to dampen the turbulence significantly.

    The thesis work involves litterature review and laboratory experiments.

  • Waves and tides in the ocean generate waves in the watertable near the coast which are of importance for water resource management in coastal areas.

    These groundwater waves are however not well understood.

    The thesis task involves measurements in a laboratory aquifer, data analysi and comparison with theories and datasets from the literature.

Possible Research Projects

Note for students: The possible research projects listed on this page may not be comprehensive or up to date. Always feel free to contact the staff for more information, and also with your own research ideas.

  • It is well known that the simple gradient diffusion model fails in relation to many geophysical and industrial mixing processes where the important eddies are not infinitesimally small compared to the scales considered. Finite mixing length models are therefore an active area of research, e g Nielsen & Teakle (2004).

    The present project will be mainly experimental, studying concentration profiles of light (rising) versus heavy (sinking) particles with numerically similar rise/sinking velocities in the same flow.

  • Much of the sand which migrates along the beaches travels in suspension.

    The mechanisms which govern such sediment suspensions are therefore of interest.

    For some combinations of wave and sand parameters stratification plays an important role. That is, for these parameter combinations, the density of the water-sand-mixture near the bed is sufficiently increased to dampen the turbulence significantly.

    The thesis work involves litterature review and laboratory experiments.

  • Waves and tides in the ocean generate waves in the watertable near the coast which are of importance for water resource management in coastal areas.

    These groundwater waves are however not well understood.

    The thesis task involves measurements in a laboratory aquifer, data analysi and comparison with theories and datasets from the literature.

  • The project will experimentally investigate the conditions under which tornado-like flows form naturally or may be triggered.

    Of special interest are

    1. Fire tornadoes, which act like 'a chimney without walls'
    2. Rotating plumes of nutrient rich water, venting from the seabed, which has the potential to sustain large-scale fish production if prevented from mixing too rapidly with surrounding water so that, it can get up to the light- and oxygen-rich environment above the thermocline.
    3. Oil-spils which, if made to rotate, will maintain enough buoyancy to come to the surface for easy cleanup
  • Beach morphodynamics: accretion, erosion and reshaping of beaches by waves will be studied broadly. The widely used but not easily defined concept of equilibrium profiles (morphoogy) will be investigated. Next the processes of change when the morphology is out of equilibrium will be studied. This includes, for a start, the time-scales of changes under regular versus irregular waves.

  • Coastal inlets are important elements of the environment, which often require management in order to prevent desease due to poor water quality or to prevent flooding. It is therefore very important to understand their natural dynamics in response to forcing by waves, tides and floods. This study will be based on recent progress by Thuy & Nielsen and make use of a large NSW government database as well as new detailed field work.

  • Wave runup generates important coastal hazards, from the riisk of fishermen getting washed off rocks to inundation and destruction of houses and road-infrastructure. While the runup process on (more or less) straight slopes like sandy beaches is fairly well understood, the runup on cliffs is not. Still the most spectacular cases of destructive runup come from cliff locations, e g, more than 50 houses were lost between 20 and 25m above sealevel on the island of Niue during Tropical Cyclone Heta in January 2004. Also, Sato et al, at Coastal Dynamics (2013) reported that the highest inundation levels associated with the 2011 Japanese tsunami, were found on cliff tops. This project incolves field measurements and associated instrument development as well as relevan theory.
