NWRG Lake Sediments and Climate Change

Event status:
EVENT CLOSED
Professor Richard Chiverril will talk about his research into lake sediment and climate change.
An Urgency Grant was awarded from the Natural Environment Research Council to study lake sedimentary records to see if they provide an insight into how extreme the floods of 2015 were in Northern England.
The project will test the robustness of the lake sediment palaeoflood record and assess the role of climate change in these events. Researchers analyse and add to unique lake sedimentary archives for the English Lake District region spanning over a 600 year period which were developed by research teams at Liverpool, Durham and Southampton Universities.
The project will analyse the recent flood sedimentation across a variety of lake environments in the Lake District region and compare the sediment records that had accumulated before and after the recent flooding, and how they evolve in the post-flood period.
It comes in the wake of the extreme floods that hit Northwest England in December 2015 and highlighted the inadequacies of current flood return frequency models developed largely using short time series, records of river flows 30-50 years in duration.
This project aims to improve confidence in our existing lake sediment palaeoflood series by placing recent extreme floods in a longer term context, and to establish flood frequency models that use integrated sediment records and river flow data in flood risk management.
