Dr Thomas Kjeldsen

MSc PhD

Profile

Thomas Kjeldsen graduated from the Technical University of Denmark with a MSc (1997) and PhD (2002), specialising in water resources engineering, before moving to the United Kingdom.

Following a year working as a consulting hydrologist, he spent a decade working as a research scientist at the Natural Environment Research Council's (NERC) Centre for Ecology & Hydrology (CEH), where he headed research into hydrological extremes.

Thomas has also spent time as a research assistant at the University of KwaZulu-Natal (South Africa) and is a visiting researcher at the National Chungbuk University (South Korea) with strong links to the Korean Institute of Construction Technology (KICT).

Thomas is an editor of the European Geophysical Union's (EGU) online open access journal Hydrology and Earth System Science.

Thomas joined the University of Bath in September 2013.

Research

Thomas's research focuses mainly on the use of mathematical and statistical modelling of environmental and hydrological systems, with emphasis on predicting extreme hydrological events such as floods and droughts. He led the scientific development underpinning the current UK industry standard methods for flood frequency analysis.

Current research efforts aim to understand the effect of environmental change (climate change, urbanisation, land-use management) on water resources systems, and he is pioneering research into risk and uncertainty analysis of extreme events.

An important aspect of his research is to maximise impact by ensuring that the research results can be translated into practical tools for use by public, private and academic institutions involved in environmental management. This requires close collaboration with external partners from government and industry.

Thomas has worked with external stakeholders, including: consulting engineering companies, water utilities, the UK Government (Defra and the Environment Agency), the European Environment Agency, and the South Korean Ministry of Lands, Transport and Maritime Affairs.

Current research projects include:

  • 2013-2016: Changes in urbanisation and its effects on water quantity and quality from local to regional scale (NERC grant NE/K002317/1)
  • 2012-2016: Development of Korean Advanced Technology for Hydrologic Analysis (Expert panel member on Collaborative project with Korean Ministry of Lands, Transport & Maritime Affairs, and National Chungbuk University, Korea)
  • 2010-2014: European procedures for flood frequency estimation (COST Action ES0901, Dr Kjeldsen is the Chair).
