BBC says 'Good management of waterways is an essential part of the fight against some of the extreme weather the UK has suffered in past years. In 2012 the country saw record levels of rainfall in some areas with about 8,000 homes flooded, and yet earlier in the year hosepipe bans followed a period of drought.'

Meteorologists are warning that extremes of weather may increase as global temperatures slowly rise, and the Environment Agency has pointed out that modelling suggests that a changing climate could reduce some summer river flows by up to 80% in the next 40 years.

LIsten to the slie show to hear Dr Dylan Bright, of the Westcountry Rivers Trust, talking about a three-year, £4m project of restoration work on river catchments across the South West of England and the ways in which this can help stabilise the country's water supply.

The conceptual models are used to illustrate the relationships between three common restoration measures (riparian buffer instalment, instream mesohabitat improvement, weir-removal), its effects on instream environmental key variables, and eventually the impact of changing variables on benthic algae, macrophytes, benthic invertebrates and fish.
