Bank erosion research within the NERC LOIS project
Dear All,
Our bank erosion project within the UK LOIS (Land-Ocean
Interaction Study), funded by NERC, has now finished. A few
details follow which may be of interest.
Project title: Dynamics of bank sediment supply and suspended
sediment transport in lower river reaches and estuaries
(Principal Investigators: D.M.Lawler, J.R.West (Civ. Eng.) &
G.J.L.Leeks (CEH); Research Assistants/Graduate Students:
John Couperthwaite, James Grove (now Durham Univ.), Steve
Mitchell (now Halcrow Maritime; soon Brighton Univ.)).
Rationale: River banks can be key sediment sources in
drainage basins (as they were in our Yorkshire Swale/Ouse
basins in N. England). Knowledge of the rates, patterns and
dynamics of bank erosion events which release sediment and
contaminants to the fluvial system is fundamental, therefore, to
a complete understanding of the sediment transport regime,
including sediment and pollutant fluxes to estuaries. Much of
our work involved automatic monitoring of bank dynamics at
Ouse basin sites with the PEEP (Photo-Electronic Erosion
Pin) system. This helped to deliver clearer pictures of bank
erosion event TIMINGS, magnitudes and frequencies, in
relation to driving variables and turbidity pulses, and
strengthen process inferences.
The project papers below have now appeared, and others are
in preparation (mainly on the dynamics side):
