human influences...
The settlement of Boscastle has been allowed to develop on a narrow flood plain on the west coast of England, where rainfall is often high. Early settlers would have been attracted by site factors such as the presence of a fresh water supply and access to a natural harbour. There are now around 1,000 permanent residents, most of who rely upon the situation of the settlement to provide tourist revenues (it is close to the South West Coast Path).
The rainfall hit at the worst time of year when the settlement population doubles to 2,000 as tourists arrive, many of who are following the South West Coast Path. Much higher levels of motor vehicle damage were also experienced, as a result of this influx. In addition, shops were carrying greater levels of stock than at other times of the year.
