Use of advanced numerical simulation for future flood resilience

This study aims to research the potential flood resilience methods and designs for future coastal structures and regions.

This study aims to research the potential flood resilience methods and designs for future coastal structures and regions. These proposed designs and methods of flood resilience need to be evaluated and proven to be viable to be taken into practice in specific wave conditions and geography. To achieve this aim, the numerical modelling can be an appropriate tool to simulate how different coastal structures and systems influence the flood wave transmission and flood water depth. Thus, the objectives of this study are to use numerical modelling effectively to construct the flooding scenario so as to investigate and evaluate the performance of the flooding resilience design.

Project outline

To analyse and evaluate the performance of flooding resilience structures, a stable and accurate numerical method is necessary. This study will use the software, OpenFOAM, to investigate the flooding resilience issues by analysing wave-structure interaction problems.

OpenFOAM is a C++ toolkit of classes for writing computational continuum mechanics codes. This research will use it to calculate CFD problems by Navier-Stokes equation, which is the core methodology of the whole study.


This research will investigate innovative designs for the protection of flooding from flood resilience aspects by considering environmental impact, sustainability and feasibility. Meanwhile, to simulate accurate flooding scenario, the practical scale simulation should be considered. Thus, the attempt of compiling external numerical model into OpenFOAM to accomplish effective large-scale simulation will be one objective of the research.


The impacts on buildings, energy and water infrastructure of climate change have a vital implication for the building environment. Flooding is one of the most serious risks which will increase due to the extreme weather and perhaps more vitally expanding urbanisation. This situation has been realized by structure engineers gradually. Meanwhile, traditional protection for flooding changes original geometry and increases building costs. This study is based on the flood resilience concept to deal with flooding issues to find out effective and sustainable solutions.
