Dr Ross Stirling

Lecturer in Geotechnical Infrastructure

Background

PhD Studentships

I am actively seeking well qualified and motivated PhD candidates in the fields of Geotechnical Engineering and Hydrology with a particular focus on environmental geotechnics (soil-plant-atmosphere interaction, hydro-thermal energy and climate change impacts), slope and buried infrastructure, sensing and monitoring, Green Infrastructure and Sustainable Drainage Systems (SuDS). Please contact me for informal enquiries.

    Background & Research Interests

    My role at Newcastle since 2016 has been to co-ordinate the research activities of the National Green Infrastructure Facility (NGIF), part of the UK Collaboratorium for Research on Infrastructure and Cities (UKCRIC) network, situated at Newcastle Helix.

    Completed in September 2017, the National Green Infrastructure Facility is a ‘living lab’ for exploring how Green features such as planting and soils (natural and amended) help mitigate the effects of climate change in urban areas, making them more resilient and sustainable. This is a world-class facility hosting collaborative, full-scale, multi-disciplinary research into Sustainable Drainage Systems (SuDS), Green Infrastructure performance and fundamental soil-plant-atmosphere interactions.

    Prior to my involvement in the NGIF, I completed a PhD in numerical modelling of desiccation cracking in unsaturated, compacted clay fill in the field of infrastructure slope stability. I then worked simultaneously on two large EPSRC funded projects –iSMART and Assessing The Underworld. There, my role was primarily as an experimentalist (laboratory and full-scale). I continue to manage the BIONICS research facility - a trial infrastructure embankment which hosts a number of innovative techniques to monitor the slope asset condition (e.g. PRIME and SlopeALARMS) as well as a comprehensive suite of buried and meteorological sensors and associated extensive dataset.

    My laboratory interests revolve around the cyclic wetting-drying behaviour of clays - specifically geotechnical properties (e.g. Soil water retention curves (SWRC), tensile and shear strength testing and small-large strain stiffness testing), geophysical techniques (i.e. resistivity) and imaging (Digital Image Correlation, Environmental-SEM and XRCT). My work also centres on understanding geotechnical deterioration mechanisms across the scales of infrastructure performance, from the soil element itself up to the network, strategic level. Through my involvement with iSMART and ATU, I have helped to develop ideas of progressive asset deterioration in the infrastructure slope and buried utility contexts, assets upon which the future resilience of our cities relies.

    Consultancy 

    I am actively engaged in geotechnical design consultancy and have worked with Electrokinetic Ltd on several slope stabilisation sites for Highways England in Cambridgeshire.  Electrokinetic Ltd provides solutions for remediating unstable slopes and dewatering slurries and sludges based on patented electrokinetic geosynthetic technology. They are recipients of numerous ICE awards owing to the outstanding sustainability credentials that electro-osmotic remediation brings.

    Together with the Environment Agency, I am supervising bank stability monitoring and analysis project on the River Tyne. The purpose of this work is to identify sustainable remediation methods that exploit coupled hydro-mechanical mechanisms to provide green, aesthetic solutions.  

    Qualifications

    • BSc (Hons) - Geology - Durham University 2008
    • MSc - Geotechnical Engineering - Newcastle University 2009
    • PhD - Multiphase modelling of desiccation cracking in compacted soils - Newcastle University 2014 (pdf)

    -        Development of a pseudo-discrete continuum finite difference model (FLAC) capable of capturing two-phase flow within a porous media subject to mechanical and hydrological boundary conditions and a tension failure criterion. Additionally, this work saw the design and development of an apparatus to establish the variable (un)saturated soil tensile strength.
