Flood Consequence Assessment, Llangadog

developmentadvicemapIt has been proposed to re-build a demolished unit behind the Telegraph Inn Llangadog, for office and storage space. Due to the proximity of the site to both the River Tywi and the Bran river, it was essential that a flood consequence assessment was undertaken, in order to forecast likely levels for the river in different return periods. Using HECRAS points supplied by Natural Resources Wales, Francis Sant estimated what the river levels are expected to be during a 1 in 100, and a 1 in 1000 event, while also considering  the impact climate change may have on these levels. It was suggested to raise the floor level as well as incorporate flood proof design while building.
