  1. Talybont Flood Group TalybontFloodees 8th and 9th June 2012

  2. The event An intense low pressure system stalled over the catchment areas of the Rivers Leri and Ceulan. Over 190mm of rain fell in 36 hours on already saturated land. The resultant flooding was widespread and severe. 27 properties in Talybont were flooded and  the A487 through the village was closed for a number of hours.

  3. The event

  4. Our Problem The Leri/Ceulan catchment is a relatively small steep sided, funnel shaped catchment which reacts very quickly to rainfall. It ranges from over 1300ft to sea level

  5. Our Problem Hydrographs for the rivers Leri, Ystwyth, Clarach and Rheidol. The Leri exhibits a highly peaked graph which provides little opportunity for an adequate warning period.

  6. Our Problem

  7. Our Problem

  8. The Solution - Knowledge Two river gauges Leri and Ceulan Talybont Two remote rain gauges at top of catchment Farson digital webcams Talybont

  9. The Solution - Knowledge Expression of interest to the ‘Nature Fund’ Developing and testing a catchment-based approach for flood alleviation in upland Wales using ecosystem services Cobweb will play a central role in allowing us to collect information within the catchment and bring issues to the notice of the authorities

  10. The Solution - Knowledge Allow the community to participate in and be pro-active in its own monitoring of the catchment We will ‘own’ the information that will allow us to fight the flood risk.
