Hydrological modelling for Talybont Community Flood Group
- Richard Dallison - Consultant
Description
This work, undertaken as part of the non-financial support obligations of the Dŵr Uisce Project, saw the completion of hydrological modelling to aid with the identification of key areas of the Afon Leri catchment to target for future natural flood risk management measures. In addition, an investigation of the impact of tree planting on average and peak flows in the catchment was completed. A report, titled Sub-basin contributions to peak flows at Talybont in the Afon Leri catchment, and the potential impact of tree planting on streamflow, was produced detailing the results of the hydrological modelling. A summary of the report was also orally presented to key group stakeholders.
The keys aims of the work were to:
The keys aims of the work were to:
• Identify the main sub-basins/areas of the catchment that contribute to peak flow events, using the Soil and Water Assessment Tool (SWAT) hydrological model.
• Investigate the impact of tree planting as a form of natural flood risk management (NFRM), to reduce peak flows in key areas of the catchment, using the Land Use Change SWAT+ Toolkit (LUCST).
• Indicate sub-basins/areas of the catchment to target for future NFRM investigation/study.
• Provide next steps to the flood group in terms of further investigation of NFRM upstream of Talybont.
