Receptor and Consequence

21st April 1947 was associated with serious flooding at Annan, Scotland with waves reportedly over 6 ft. [1.8 m] high during an abnormally high tide (Hickey, 1997) This was attributed to a south-easterly gale with maximum wind speeds at Renfrew airport around 61 knots [31 m/s] and averaging 35 knots [18 m/s]. The loading station of a cement store on Port St. was submerged by 6 ft. [1.8 m] of water, and there was serious flooding at the mouth of the River Annan. Extensive, deep flooding was also reported at Welldale where over 20 m2 were affected. On 22nd April 1947 there was continued flooding, with “deep” flood water reported at Welldale (Hickey ,1997). During 23rd April 1947, it is reported that large tracts of land were flooded in the Solway Firth (Hickey, 1997). Near the River Sark the floodwater affected agricultural land 0.5 miles [0.8 km] from the shore. In Annan, local roads alongside the harbour were once again inundated (from the previous two days). Examining meteorological data it is clear that the floods from 21st–22nd April 1947 are associated with the same storm. The inundation reported for 23rd April 1947 may have been from those events, or possibly as a result of a storm that followed quickly after.
