Dr Sangaralingam Ahilan is a research fellow at the Centre for Water Systems in the College of Engineering Mathematics and Physical Sciences.  He received the bachelor degree in civil engineering from University of Moratuwa, Sri Lanka; Master of Applied Science degree in Engineering hydrology from National University of Ireland, Galway and Ph.D. from University College Dublin, Ireland.  Dr Ahilan has worked in a number of water and environmental research projects in Ireland and UK.

Dr Ahilan took part in Irish National Flood Studies Update programme as part of his Ph.D. research.  In this research, he investigates influences of floodplain attenuation effects on Irish flood estimation procedures.  In the Ireland, he took part in the EU Water Framework Directive (HYDROFOR, SILTFLUX) and the EU Bathing Water Directive projects (Smart Coasts) involved in field sampling of the Irish rivers and sea, water quality analysis and statistical modelling.  

In the UK, Ahilan’s research work is centred on the sustainable urban flood risk management in the UK cities.  He worked in the EPSRC funded 'Blue-Green Cities' and SESAME research projects.  As part of the Blue-Green Cities project, he investigates the long-term performance of sustainable drainage systems using detailed hydrological and hydro-morphodynamic modelling.  In the SESAME project, he has contributed to the agent-based modelling to understand the interactions of the small medium enterprises with suppliers and customers during and the aftermath of the flooding. At present Ahilan studies the potential of rainwater harvesting system to provide non-potable water supply and flood resilience for UK cities and, the flexible design of the urban infrastructures to achieve urban flood resilience in an uncertain future.
