<h2 class="heading hide-accessible">Summary</h2>

Future climate projections predict significant changes in seasonal weather patterns. These will have profound effects on transport infrastructure. For example, rising sea-levels will damage coastal transport networks, increased heat will result in increased highway rutting and railway buckling, and changes in rainfall will result in increased transport earthwork failures. Much of existing transport infrastructure is not well-suited to cope with the increased demands due to climate change. Therefore disruption to transport networks is a significant threat. Thus, this project will study projected changes in climate and their effect on transport infrastructure. Then, new methodologies will be developed to make transport networks more resilient to climate change.

<h2 class="heading hide-accessible">Full description</h2>

Some transport engineering challenges associated with climate change include:   Rainfall:  Changes in rainfall and evapotranspiration result in changes in moisture levels within transport earthworks and subgrades.  This can result in geotechnical instabilities, slope collapse and increased rates of settlement.   Flooding:  An increased frequency of high-impact rainfall events will result in more frequent flooding of transport networks.  These events will reduce the stability of railway assets and cause washouts.   Sea-level rise: Rising sea levels cause overtopping of sea defences and also increased degradation of sea defence assets.   Storms: Increased storm frequency and intensity can cause high winds and sea swells.  High winds can result in transport vehicles being blown off their guideway (particularly elevated structures such as bridges and embankments) and debris blown onto the network.   Heat:  Temperature changes have cause the expansion of steel railway rails which can result in track buckling and thus derailments.  Increased heat also causes railway overhead lines to sag, increasing the likelihood of dewirements.  Also, it causes rutting of asphalt highway structures.   To address these issues this project will review a wide range of possible railway impacts due to climate change.  Based upon the review the candidate will identify their preferred area of climate change study and investigate it using a combination of numerical modelling and field data analysis.  Due to the novelty of the research and model development, there is the opportunity to write multiple world-leading, international journal papers on the subject.  Considering the international nature of the research, candidates will be expected to attend international conferences if required.

Applications will be considered on an ongoing basis.  Potential applicants are strongly encouraged to contact the supervisors for an informal discussion before making a formal application. We also advise that you apply at the earliest opportunity as the application and selection process may close early, should we receive a sufficient number of applications or that a suitable candidate is appointed. Please note that you must provide the following documents at the point you submit your application: <ul> <li>Full Transcripts of all degree study or if in final year of study, full transcripts to date</li> <li>Personal Statement outlining your interest in the project</li> <li>CV</li> </ul>

<h2 class="heading heading--sm">Entry requirements</h2>

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

<h2 class="heading heading--sm">English language requirements</h2>

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
