SMART Seminar Series
April 24, 2019 @ 11:30 am - 12:30 pm
Presenter: Professor Shunqi Pan
Shunqi Pan is Professor of Coastal Engineering and Director of Hydro-environmental Research Centre at School of Engineering, Cardiff University. He has more than 25 years research experience in coastal engineering, ranging from physical and numerical modelling of coastal and estuarine processes, particularly with interaction with the nearshore coastal defense structures, as well as modelling of large-scale waves/tides/surge prediction under extreme conditions, resource characterization for marine renewable energy and the impact of climate change on coasts and estuaries in recent years.
Since 2000, he has been a Principal Investigator or Co-investigator for some 25 research projects funded by EPSRC, NERC and other sources, and secured more than £3m research funds. He has published more than 120 papers in international journals and conferences. He received the Halcrow Prize from the Institution of Civil Engineers (ICE) in 2007.
Currently, he is a member of the EPSRC peer-review college, an Associate Editor of Water Science and Engineering, and a member of the editorial board of China Ocean Engineering, having previously served in the editorial board of the Institution of Civil Engineers (ICE) Maritime Engineering Journal (2009-2012). He is an Environmental Partner member of the Chartered Institution of Water and Environmental Management (CIWEM). He also has developed strong international research collaborations, particularly in China, Taiwan and Japan.
Title: Coastal Reservoir for London’s water supply
According to UN-endorsed projections with global demand for fresh water to exceed supply by 40% by 2030, the Greater London in the United Kingdom is the one amongst the 11 cities most likely to run out of drinking water.
Currently, the Greater London has a population of 9 million, and the present water consumption is more than 2.6 billion litres/day, which is equivalent to 26 times of the Royal Albert Hall. The water is mainly supplied from Rivers Thames and Lee. However, the city is under increasing pressure from the shortage of water due to the population growth and climate change. By 2025, the city will experience the problems in its water supply, and it will have serious shortage of water resources by 2040. The average total discharge of both Thames and Lee rivers amounts merely 71 m3/s, of which approximately 20% will be used for the water demand of the city.
As a practical measure to mitigate the shortage of water resources, a coastal reservoir can be considered for the Great London by utilizing the Medway Estuary located in the south of the Thames estuary. In this talk, the detail of the numerical model based on TELEMAC-2D are described. The model results will show the impact of the closure of the Medway Estuary on the hydrodynamics, salinity distributions and water resources as the coastal reservoir is proposed. The feasibility and location of the water diversion from the Thames River to the coastal reservoir is also explored.
