About this event

Join this free evening lecture on Monday 27 February, when Nigel Pontee will present his award-winning work on the impact of managed realignment design on estuarine water levels.

Realignment schemes can make a valuable contribution to sustainable coastal management, potentially offering social and economic benefits as well as environmental gains. However, these schemes can have an impact on water levels in estuaries.

Changes in water levels may also be accompanied by changes in flow speeds, which can in turn impact on erosion/accretion and morphology within an estuary. Changes in water levels can also potentially have impacts on flood risk and the extent of internationally protected intertidal habitats.

At this lecture delegates will:

  • Explore the factors that influence changes in water levels and learn how to design schemes successfully
  • Discuss the potential for managed realignments to increase water levels within an estuary
  • Look at the various breach options that were explored in the design of a managed realignment scheme in south west England
  • Hear about the the impacts of the different scheme options on estuarine water levels as predicted by hydrodynamic modelling

The lecture will be followed by a questions and answers session. Discussions will then continue at the commentary drinks reception.
