Project title

Extreme summer flooding and ecosystem processes in Glacier Bay, Alaska.

Project overview

Under climate change, extreme events including heavy rainfall and subsequent flooding are predicted to increase in frequency/magnitude. However, historically, studies associated with climate change have focussed on general long term trends in change, routinely ignoring the increased potential for extreme events. Flooding can cause a range of negative impacts to river ecosystems but surprisingly few studies have compared pre- and post-flood response. Timing of flooding is also thought to play a major role in the significance of impacts, yet there is limited field data addressing the role seasonal variation in the effects of flooding. The summer of 2014 saw significant, prolonged, heavy rainfall in SE Alaska resulting in a number of large, atypical, flooding events.


This project aims to address the question of the short-term geomorphic and ecological effects and rate of recovery relative to long term (30 years+) pre-flood datasets collected following glacier retreat. Alongside this, the project will compare the impacts of cumulative summer flooding with that of a 1 in 100 year winter flood that occurred in 2005.
