Effect of Climate Change on River Flows and Groundwater Recharge, A Practical Methodology: Trends in UK River Flows 1970-2002
Since the late 1980s the UK climate has suffered from a series of dry periods, such as the 1995 drought, and a number of severe floods, such as the flash flooding in Boscastle in August 2004. These events have raised concerns that climate change is causing an increase in the frequency and magnitude of extreme hydrological conditions.
The main objective for this report was to detect trends in river flows for the period 1970 to 2002. The report describes an analysis of 47 river flow records and 10 groundwater observational wells that aimed to detect any early signals of climate change due to changes in the seasonal water balance. Some short to medium term upward trends in autumn and winter river flow were identified but it is not possible, at this stage, to attribute these changes to climate change rather than natural climate variability.
The main benefit of the study is that it provides a framework for the water industry to periodically review trends in river flow and compare these with a range of possible future climate scenarios.
