Water Engineering



You can find below an overview of the research we do, classified in four main categories. You can alternatively explore the research we do by academic. Also, check out our Hydraulics Facilities.


Low head hydropower

New hydropower converters are under development which can use head differences below 2.5 m as a source of renewable energy. Unlike conventional turbine technology, these systems can be used in a cost effective and ecologically acceptable way. Two prototypes built and monitored in the EU FP7-funded project Hylow have shown efficiencies  from 75-85%. Tests show that the converters can be used successfully in conjunction with fish and sediment passages. Work to expand the area of application and to improve the technology is continuing.



Environmental Fluid Mechanics

Research areas include the interaction between Turbulent Boundary Layers with groups of fixed or moving bodies (e.g. wind farms or fish schools); prediction of local scour around bridge piers and off-shore structures; development of numerical models to simulate free surface flows for urban and coastal flooding; flow resistance and sediment transport in geophysical flows; mathematical modelling of open channel morphodynamics .


Hydrology and water resources

EPSRC-funded research on surface zone infiltration into engineered clay slopes has shown that climate change will lead to increased risk of instability. Aquifer recharge modelling shows that water tables may fall between 1-2 m by the end of the century in the UK. Coastal flood risk is being evaluated for new nuclear power stations in the UK, and for Bangladesh as part of the NERC/DFID ‘Ecosystems for Poverty Alleviation’ programme. The first Windows version of CROPWAT was written in Southampton for the UN’s    Food and Agricultural Organisation. This software is being used worldwide for regional water resources evaluation.
