The valley has been flooded many times , most seriously in the Boscastle flood of 2004 when significant channel erosion occurred . ( Heavy rainfall for 7 hours over a wide area in the afternoon of 16 August 2004 led to severe flooding and structural damage . ) The agricultural use and fast drainage within the catchment areas of the Valency and Jordan are related to the extent of the Boscastle flooding
