On 16 August 2004, exceptionally intense and prolonged storm conditions centred over the North Cornwall coast and the headwaters of Bodmin Moor generated extreme flooding in and above the coastal villages of Boscastle and Crackington Haven. The event – which wreaked havoc and damage, but led to no direct loss of life – captured considerable media attention. “What happened? Why there? How? How unusual was it? What’s the risk of it happening again, there and elsewhere? What’s being done? [and yes] Is climate change to blame?” style questions peppered the press, and occupied the minds of many, at the time and after. This paper addresses the “what happened?” question. It reports on a flood forensics study carried out for the Environment Agency by HR Wallingford, with support from Halcrow, Royal Haskoning, The Met Office, CEH Wallingford and others. The event, from storm to runoff to flood to impact, has been reconstructed using best available evidence and applying best possible analyses (meteorological, hydrological and hydraulic). Propagation mechanisms – and features like the reported “walls of water” observed during the event - are investigated with a numerical model calibrated against evidence of peak water levels. Estimates are provided of the peak flow and peak water levels experienced, and their probabilities; these place the event amongst the most extreme ever to have occurred in the region and in the UK.

Using the Teachit Geography template, this sorting exercise provides a framework for investigating cause of, effect of and response to the 2004 Boscastle flood.
The flood on 16 August 2004 in Boscastle in Cornwall was the worst in local memory and an Environment Agency report concluded that it was among the most extreme ever experienced in Britain.
There was a combination of human and physical causes contributing to a series of effects and impacts. The responses to the flood were both short and long term. Sort statements to show these causes, effects and responses, e.g. loss of businesses, water gauging stations were installed, Boscastle is at the confluence of three rivers, etc.
