Hydraulic modelling of global rivers has become an important tool in assessing environmental issues such as flood risk, navigation and hydroelectric power. Due to the scale of the modelling task and limited data available for most of the globe, these models employ approximations in their representations of the river channels. However, the applicability and usefulness of these approximations has not yet been demonstrated.
This PhD will focus on identifying better representations for complex braided channels in these large scale, simple-geometry based models, by investigating the detailed hydraulics of navigable reaches of the Congo River through 2D or 3D computational fluid dynamics. Detailed modelling will be undertaken for short representative reaches where bathymetry data are available from an existing project. Experiments with simplifications of the channel representation and flow physics can then be compared to the detailed modelling in order to identify useful model approximations and the cost to model accuracy.
In addition, there will be an opportunity to study the derivation of approximate river bathymetry from optical remote sensing. The feasibility of this has been demonstrated in a pilot project for a small area where measured bathymetry is available. It will be possible to apply this to a larger reach and use the detailed numerical models developed for this PhD to understand how this approximate bathymetry affects model accuracy.
By the end of the PhD, the student will have strong skills in numerical modelling, remote sensing, and analysis, all highly sought after in both academic and commercial sectors. The project has the potential to make a significant difference to a growing and important field of global river modelling.

How to apply
To apply for a Leeds Anniversary Research Scholarship, you must submit two separate applications forms:
Research degree application: first of all you, you must apply for a research degree online through the university's website. Please state clearly in the research information section that the PhD you wish to be considered for is the 'Numerical modelling of the Congo River’s complex braided channel hydraulics and remote sensing of its bathymetry’ as well as Dr Mark Trigg as your proposed supervisor. You will receive an acknowledgement email which will include your Student ID Number within 24 hours of submitting your application.
Leeds Anniversary Research Scholarship application: once you are in receipt of a Student ID Number, you must then apply for funding by the deadline by completing the Leeds Anniversary Research Scholarships form. Applications for this scheme are now open. Please download the application form for further details.
For International Applicants, please note that you must have met the English Language requirements by the closing date of Wednesday 1 June 2016 to be eligible for the Leeds Anniversary Research Scholarship.
