I am looking for a talented individual with an inquisitive mind, interested in undertaking a challenging PhD project in my Auckland research group. Ideally, applicants will have outstanding academic records from a top University and are highly motivated to take on a new challenge. You can read more about my Water-worked Environments Research Group here http://water.auckland.ac.nz/. I am committed to provide a research environment that allows young researchers to grow. You are part of a growing research team that values diversity and creativity.
Project description – start March 1, 2015, or earliest thereafter:
The research is a collaborative effort with scientists from the Department of Computer Science. Up until now there has been no suitable measurement equipment available to undertake an experimental laboratory study to observe, quantify and better understand surface/sub-surface sediment dynamics of gravel beds. We are in the unique position to capture for the first time the detailed grain roughness for natural gravel-bed evolution, allowing us to study the integral role individual sediment particles play in multiscale transport phenomena. We use our world’s leading close-range 3D stereo-vision (3DSV) system. The experiments are designed to spatially and temporally decompose the evolution of the structured sediment bed to contribute to the overall project goal of enhancing our insight into the dynamic processes that take place at the interface between flow and mobile boundary at the grain scale. The main outcomes of the projects are to quantitatively describe the detailed grain-scale dynamics of fluvial bed roughness for various flow conditions under steady as well as unsteady flow. New frameworks of sediment transport mechanics are needed to better calibrate sediment transport computational models, which can then be incorporated into morphodynamic models used by practitioners to forecast sediment transport and channel morphology changes.
