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

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.

The Solution - KnowledgeExpression 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

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.
